+/*
+ *	Description:
+ *	a) Optical transceiver EEPROM read/write transactions are just like
+ *		the at24 eeproms managed by the at24.c i2c driver
+ *	b) The register/memory layout is up to 256 128 byte pages defined by
+ *		a "pages valid" register and switched via a "page select"
+ *		register as explained in below diagram.
+ *	c) 256 bytes are mapped at a time. 'Lower page 00h' is the first 128
+ *	        bytes of address space, and always references the same
+ *	        location, independent of the page select register.
+ *	        All mapped pages are mapped into the upper 128 bytes
+ *	        (offset 128-255) of the i2c address.
+ *	d) Devices with one I2C address (eg QSFP) use I2C address 0x50
+ *		(A0h in the spec), and map all pages in the upper 128 bytes
+ *		of that address.
+ *	e) Devices with two I2C addresses (eg SFP) have 256 bytes of data
+ *		at I2C address 0x50, and 256 bytes of data at I2C address
+ *		0x51 (A2h in the spec).  Page selection and paged access
+ *		only apply to this second I2C address (0x51).
+ *	e) The address space is presented, by the driver, as a linear
+ *	        address space.  For devices with one I2C client at address
+ *	        0x50 (eg QSFP), offset 0-127 are in the lower
+ *	        half of address 50/A0h/client[0].  Offset 128-255 are in
+ *	        page 0, 256-383 are page 1, etc.  More generally, offset
+ *	        'n' resides in page (n/128)-1.  ('page -1' is the lower
+ *	        half, offset 0-127).
+ *	f) For devices with two I2C clients at address 0x50 and 0x51 (eg SFP),
+ *		the address space places offset 0-127 in the lower
+ *	        half of 50/A0/client[0], offset 128-255 in the upper
+ *	        half.  Offset 256-383 is in the lower half of 51/A2/client[1].
+ *	        Offset 384-511 is in page 0, in the upper half of 51/A2/...
+ *	        Offset 512-639 is in page 1, in the upper half of 51/A2/...
+ *	        Offset 'n' is in page (n/128)-3 (for n > 383)
+ *
+ *	                    One I2c addressed (eg QSFP) Memory Map

+ * Mix this utility code with some glue code to get one of several types of

+ *
+ *   -	GPIO/parport bitbangers.  Provide chipselect() and txrx_word[](),
+ *	expanding the per-word routines from the inline templates below.
+ *
+ *   -	Drivers for controllers resembling bare shift registers.  Provide
+ *	chipselect() and txrx_word[](), with custom setup()/cleanup() methods
+ *	that use your controller's clock and chipselect registers.
+ *
+ * Some hardware works well with requests at spi_transfer scope:
+ *
+ *   -	Drivers leveraging smarter hardware, with fifos or DMA; or for half
+ *	duplex (MicroWire) controllers.  Provide chipselect() and txrx_bufs(),
+ *	and custom setup()/cleanup() methods.
+ */
+
+/*
+ * The code that knows what GPIO pins do what should have declared four
+ * functions, ideally as inlines, before including this header:
+ *
+ *  void setsck(struct spi_device *, int is_on);
+ *  void setmosi(struct spi_device *, int is_on);
+ *  int getmiso(struct spi_device *);
+ *  void spidelay(unsigned);
+ *
+ * setsck()'s is_on parameter is a zero/nonzero boolean.
+ *
+ * setmosi()'s is_on parameter is a zero/nonzero boolean.
+ *
+ * getmiso() is required to return 0 or 1 only. Any other value is invalid
+ * and will result in improper operation.
+ *
+ * A non-inlined routine would call bitbang_txrx_*() routines.  The
+ * main loop could easily compile down to a handful of instructions,
+ * especially if the delay is a NOP (to run at peak speed).
+ *
+ * Since this is software, the timings may not be exactly what your board's
+ * chips need ... there may be several reasons you'd need to tweak timings
+ * in these routines, not just to make it faster or slower to match a
+ * particular CPU clock rate.

+# SONiC ECMP Calculator
+
+## Description
+An equal cost multipath (ECMP) is formed when routing table contains multiple next hop addresses for the same destination IP address.
+ECMP will load balance the outbound traffic between the IP interfaces. 
+The purpose of ECMP calculator is to calculate which IP interface ECMP will choose and return the physical interface packet will egress from. 
+Packet is defined by a JSON file given as an argument to the tool.
+
+## Usage notes
+1.  ECMP calculator performs its calculations based on the current operational state of the router. In order to calculate the egress port, it fetches routes from HW. Routes exist in HW only for next hops with a resolved ARP.
+2.  ECMP calculator supports only routed packets.
+-   IPv4/IPv6 TCP/UDP packets
+-   IPinIP and VXLAN encapsulated packets
+3.  Changes done in the packet classification (e.g. ACL, PBR) are not taken into consideration during calculation.
+
+## Command line interface
+1.  User shall enter syncd container to run ECMP calculator.
+2.  User shall provide the following input parameters:
+- JSON file describing a packet
+- Ingress port (e.g. "Ethernet0", must pe a physical interface)
+- Debug option for debug purposes (optional)
+- VRF name (optional)
+3.  Usage example:
+```
+$ docker exec -it syncd bash
+$ /usr/bin/ecmp_calc.py -i Ethernet0 -p ./packet.json -v Vrf_red
+Egress port: Ethernet4
+```
+```
+$ docker exec -it syncd bash
+$ /usr/bin/ecmp_calc.py -h
+usage: ecmp_calc.py [-h] -i INTERFACE -p PACKET [-v VRF] [-d]
+
+ECMP calculator
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -i INTERFACE, --interface INTERFACE
+                        Ingress interface
+  -p PACKET, --packet PACKET
+                        Packet description
+  -v VRF, --vrf VRF     VRF name
+  -d, --debug           Flag for debug
+
+```
+
+## Packet JSON
+1.  Numbers in packet JSON must be in base-ten.
+2.  For packets with single header, outer header shall be provided.
+3.  The following table defines the structure of a packet JSON file.
+
+| ecmp_hash |             |       |             |             |        |                                                                                  |

 ## Mellanox non-upstream linux kernel patches ##
 
-To include non-upstream patches into the sonic-linux image during build time, this folder must contain a patch archive.
-
-### Structure of the patch archive
-
-  1. It should contain a file named series. series should provide an order in which the patches have to be applied
-  ```
-  admin@build-server:/sonic-buildimage/src/sonic-linux-kernel$ cat linux-5.10.103/non_upstream_patches/series
-  mlx5-Refactor-module-EEPROM-query.patch
-  mlx5-Implement-get_module_eeprom_by_page.patch
-  mlx5-Add-support-for-DSFP-module-EEPROM-dumps.patch
-  ```
-  2. All the patches should be present in the same folder where series resides.
-  3. Developers should make sure patches apply cleanly over the existing patches present in the src/sonic-linux-kernel .
-  4. Name of the tarball should match with the one specified under EXTERNAL_KERNEL_PATCH_TAR
+To include non-upstream patches into the sonic-linux image during build time, the `INCLUDE_EXTERNAL_PATCHES=y` flag has to be provided. By default, the directory pointed by EXTERNAL_KERNEL_PATCH_LOC will be used and it must follow the following structure. To use a publicly accessible tar of the non-upstream patches, also provide the `EXTERNAL_KERNEL_PATCH_URL` variable 
+

-### Include the archive while building sonic linux kernel
+  1. It should contain a file named series.patch. This should contain a diff that is applied on the sonic-linux-kernel/patch/series file. The diff should include all the non-upstream patches.
+  2. All the patches should be present in the patches folder
+  3. Developers should make sure patches apply cleanly over the existing patches present in the src/sonic-linux-kernel .
+
+
+### Include the non upstream patches while building sonic linux kernel
+
+Set `INCLUDE_EXTERNAL_PATCHES=y` using `SONIC_OVERRIDE_BUILD_VARS` to include these changes before building the kernel.
+- Eg: `NOJESSIE=1 NOSTRETCH=1 NOBUSTER=1 make SONIC_OVERRIDE_BUILD_VARS=' INCLUDE_EXTERNAL_PATCHES=y ' target/debs/bullseye/linux-headers-5.10.0-12-2-common_5.10.103-1_all.deb`
 
-Set `INCLUDE_EXTERNAL_PATCH_TAR=y` using `SONIC_OVERRIDE_BUILD_VARS` to include these changes before building the kernel.

+Subject: [PATCH] mlxsw: core_hwmon: Fix variable names for hwmon attributes
+
+Replace all local variables 'mlwsw_hwmon_attr' by 'mlxsw_hwmon_attr'.
+All variable prefixes should start with 'mlxsw' according to the naming
+convention, so 'mlwsw' is changed to 'mlxsw'.

+
+Extend MTMP (Management Temperature Register) with new field specifying
+the slot index. The purpose of this field is to support access to MTMP
+register for reading temperature sensors on modular systems.
+For non-modular systems the 'sensor_index' uniquely identifies the cage
+sensors, while 'slot_index' is always 0. For modular systems the
+sensors are identified by:
+- 'slot_index', specifying the slot index, where line card is located;
+- 'sensor_index', specifying cage sensor within the line card.

+Subject: [PATCH] mlxsw: reg: Extend MGPIR register with new slot fields
+
+Extend MGPIR (Management General Peripheral Information Register) with
+new fields specifying the slot number and number of the slots available
+on system. The purpose of these fields is:
+- to support access to MPGIR register on modular system for getting the
+  number of cages, equipped on the line card, inserted at specified
+  slot. In case slot number is set zero, MGPIR will provide the
+  information for the main board. For Top of the Rack (non-modular)
+  system it will provide the same as before.
+- to provide the number of slots supported by system. This data is
+  relevant only in case slot number is set zero.

+From: Vadim Pasternak <vadimp@nvidia.com>
+Date: Tue, 14 Dec 2021 10:57:27 +0200
+Subject: [PATCH] mlxsw: core: Extend port module data structures for line
+ cards
+
+The port module core is tasked with module operations such as setting
+power mode policy and reset. The per-module information is currently
+stored in one large array suited for non-modular systems where only the
+main board is present (i.e., slot index 0).
+
+As a preparation for line cards support, allocate a per line card array
+according to the queried number of slots in the system. For each line
+card, allocate a module array according to the queried maximum number of
+modules per-slot.

+Subject: [PATCH] mlxsw: core: Move port module events enablement to a separate
+ function
+
+Use a separate function for enablement of port module events such
+plug/unplug and temperature threshold crossing. The motivation is to
+reuse the function for line cards.

+Subject: [PATCH] mlxsw: core_hwmon: Split gearbox initialization
+
+Split gearbox initialization in two functions - the first one is to be
+used for gearbox configuration validation, the second for creation of
+gearbox related hwmon attributes, if any.
+
+Currently, mlxsw supports gearbox hwmon attributes corresponding to the
+objects discovered on the main board. Same hwmon attributes could be
+also discovered on line cards. While the initialization flow for main
+board and for line cards is the same, the configuration flow is
+different.
+
+The purpose of this patch is to allow reusing of initialization flow by
+main board and line cards.

+Subject: [PATCH] mlxsw: core_hwmon: Extend internal structures to support
+ multi hwmon objects
+
+Currently, mlxsw supports a single hwmon device and registers it with
+attributes corresponding to the various objects found on the main
+board such as fans and gearboxes.
+
+Line cards can have the same objects, but unlike the main board they
+can be added and removed while the system is running. The various
+hwmon objects found on these line cards should be created when the
+line card becomes available and destroyed when the line card becomes
+unavailable.
+
+The above can be achieved by representing each line card as a
+different hwmon device and registering / unregistering it when the
+line card becomes available / unavailable.
+
+Prepare for multi hwmon device support by splitting
+'struct mlxsw_hwmon' into 'struct mlxsw_hwmon' and
+'struct mlxsw_hwmon_dev'. The first will hold information relevant to
+all hwmon devices, whereas the second will hold per-hwmon device
+information.

+Date: Tue, 14 Dec 2021 10:57:31 +0200
+Subject: [PATCH] mlxsw: core_hwmon: Introduce slot parameter in hwmon
+ interfaces
+
+Add 'slot' parameter to 'mlxsw_hwmon_dev' structure. Use this parameter
+in mlxsw_reg_mtmp_pack(), mlxsw_reg_mtbr_pack() and
+Use mlxsw_reg_mtmp_slot_index_set() routines.
+For main board it'll always be zero, for line cards it'll be set to
+the physical slot number in modular systems.

+Subject: [PATCH] mlxsw: core_hwmon: Extend hwmon device with gearbox mapping
+ field
+
+Add gearbox mapping field to 'mlxsw_hwmon_dev' structure. It should
+provide the mapping for gearbox sensor indexes, given gearbox number.
+For main board mapping is supposed to be always sequential, while for
+line cards on modular system it could be non-sequential.

+Subject: [PATCH] mlxsw: core_thermal: Extend internal structures to support
+ multi thermal areas
+
+Introduce intermediate level for thermal zones areas.
+Currently all thermal zones are associated with thermal objects located
+within the main board. Such objects are created during driver
+initialization and removed during driver de-initialization.
+
+For line cards in modular system the thermal zones are to be associated
+with the specific line card. They should be created whenever new line
+card is available (inserted, validated, powered and enabled) and
+removed, when line card is getting unavailable.
+The thermal objects found on the line card #n are accessed by setting
+slot index to #n, while for access to objects found on the main board
+slot index should be set to default value zero.
+
+Each thermal area contains the set of thermal zones associated with
+particular slot index.
+Thus introduction of thermal zone areas allows to use the same APIs for
+the main board and line cards, by adding slot index argument.

+Subject: [PATCH] mlxsw: core_thermal: Split gearbox initialization
+
+Split gearbox initialization in two routines - the first one is to be
+used for gearbox configuration validation, the second for creation of
+gearbox related thermal zones if any.
+
+Currently, mlxsw supports gearbox thermal zones corresponding to the
+main board. For system equipped with the line cards assembled with the
+gearboxes, thermal zones will be associated with the gearboxes found on
+those line cards.
+
+While the initialization flow for main board and for line cards is the
+same, the configuration flow is different.
+
+The purpose of this patch is to allow reusing of initialization flow by
+main board and line cards.

+Subject: [PATCH] mlxsw: core_thermal: Extend thermal area with gearbox mapping
+ field
+
+Add gearbox mapping field 'gearbox_sensor_map' to
+'mlxsw_thermal_module' structure. It should provide the mapping for
+gearbox sensor indexes, given gearbox number. For main board mapping is
+supposed to be always sequential, while for line cards on modular
+system it could be non-sequential.

+From: Vadim Pasternak <vadimp@nvidia.com>
+Date: Wed, 22 Dec 2021 08:57:27 +0000
+Subject: [PATCH] devlink: add support to create line card and expose to user
+
+Extend the devlink API so the driver is going to be able to create and
+destroy linecard instances. There can be multiple line cards per devlink
+device. Expose this new type of object over devlink netlink API to the
+userspace, with notifications.

+Subject: [PATCH] devlink: implement line card provisioning
+
+In order to be able to configure all needed stuff on a port/netdevice
+of a line card without the line card being present, introduce line card
+provisioning. Basically by setting a type, provisioning process will
+start and driver is supposed to create a placeholder for instances
+(ports/netdevices) for a line card type.
+
+Allow the user to query the supported line card types over line card
+get command. Then implement two netlink command SET to allow user to
+set/unset the card type.
+
+On the driver API side, add provision/unprovision ops and supported
+types array to be advertised. Upon provision op call, the driver should
+take care of creating the instances for the particular line card type.
+Introduce provision_set/clear() functions to be called by the driver
+once the provisioning/unprovisioning is done on its side. These helpers
+are not to be called directly due to the async nature of provisioning.
+

+Subject: [PATCH] devlink: add port to line card relationship set
+
+In order to properly inform user about relationship between port and
+line card, introduce a driver API to set line card for a port. Use this
+information to extend port devlink netlink message by line card index
+and also include the line card index into phys_port_name and by that
+into a netdevice name.

+
+devlink: introduce line card devices support
+
+Line card can contain a device. For example, this can be a gearbox with
+flash. This flash could be updated. Provide the driver possibility to
+attach such devices to a line card and expose those to user. Leverage
+the existing devlink flash update mechanism and allow driver to pass a
+custom "component name" string identifying the line card device to
+flash.

+Subject: [PATCH] mlxsw: core: Extend driver ops by remove selected ports op
+
+In case of line card implementation, the core has to have a way to
+remove relevant ports manually. Extend the Spectrum driver ops by an op
+that implements port removal of selected ports upon request.

+
+For each port get slot_index using PMLP register. For ports residing
+on a linecard, identify it with the linecard by setting mapping
+using devlink_port_linecard_set() helper. Use linecard slot index for
+PMTDB register queries.

+
+Add APIs mlxsw_env_sensor_map_init() and mlxsw_env_sensor_map_fini(().
+The purpose of the first one is to allocate and create thermal sensors
+mapping for temperature sensors, presented within the main board or
+line card. It obtains mapping information from the Management
+Temperature Extended Capabilities Register, by specifying the relevant
+device by the number of a slot at which this device is located. Slot
+zero is used for the main board. The second API just free allocated
+memory.
+The motivation is to create dynamic mapping for gearbox thermal sensors
+access.

+Subject: [PATCH] mlxsw: core: Introduce flash update components
+
+Introduce an infrastructure allowing to have multiple components for
+flashing purposes that can be registered from inside the driver. Convert
+the existing "no component" flash update to use the new infra.

+Subject: [PATCH] mlxsw: core_linecards: Implement line card device flashing
+
+Generate flash component name and register it internally within mlxsw
+for flashing. Also, propagate the component name to devlink core which
+exposes the information about device being flashable and the component
+name to use to the user. Implement flashing using MDDT register and
+mlxfw.

+Subject: [PATCH] mlxsw: core_thermal: Add interfaces for line card
+ initialization and de-initialization
+
+Add callback functions for line card thermal area initialization and
+de-initialization. Each line card is associated with the relevant
+thermal area, which may contain thermal zones for cages and gearboxes
+found on this line card.
+
+The line card thermal initialization / de-initialization APIs are to be
+called when line card is set to active / inactive state by
+got_active() / got_inactive() callbacks from line card state machine.
+
+For example thermal zone for module #9 located at line card #7 will
+have type:
+mlxsw-lc7-module9.
+And thermal zone for gearbox #2 located at line card #5 will have type:
+mlxsw-lc5-gearbox2.
+
+For now the slot index is always 0 and field 'name' of the structure
+'mlxsw_hwmon_dev' is empty. For line card this field is supposed to
+be initialized to 'lc#n', when line card in slot #n is enabled.
+
+Add validation of modules number found on main board in function
+mlxsw_thermal_modules_init(). On modular system this counter might be
+zero.

+Subject: [PATCH] mlxsw: core_hwmon: Add interfaces for line card
+ initialization and de-initialization
+
+Add callback functions for line card 'hwmon' initialization and
+de-initialization. Each line card is associated with the relevant
+'hwmon' device, which may contain thermal attributes for the cages
+and gearboxes found on this line card.
+
+The line card 'hwmon' initialization / de-initialization APIs are to be
+called when line card is set to active / inactive state by
+got_active() / got_inactive() callbacks from line card state machine.
+
+For example cage temperature for module #9 located at line card #7 will
+be exposed by utility 'sensors' like:
+linecard#07
+front panel 009:	+32.0C  (crit = +70.0C, emerg = +80.0C)
+And temperature for gearbox #3 located at line card #5 will be exposed
+like:
+linecard#05
+gearbox 003:		+41.0C  (highest = +41.0C)

+Subject: [PATCH] mlxsw: minimal: Prepare driver for modular system support
+
+As a preparation for line cards support:
+- Allocate per line card array according to the queried number of slots
+  in the system. For each line card, allocate a port mapping array
+  according to the queried maximum number of ports available in system.
+  Port mapping array includes port object handle, local port number and
+  module number.
+- Extend port creation APIs with 'slot_index' argument.
+- Extend port structure with slot index and module offset for this slot
+  index.
+
+For main board, slot will always be set to zero and these APIs will work
+as before. For the ports located on line cards, slot should be set to the
+physical slot number, where line card is located in modular systems.

+Subject: [PATCH] mlxsw: i2c: Add support for system events handling
+
+Extend i2c bus driver with interrupt handler to support system specific
+hotplug events, related to line card state change.
+Provide system IRQ line for interrupt handler. Line Id could be
+provided through the platform data if available, or could be set to the
+default value.
+Handler is supposed to be set by "mlxsw" driver through bus driver init()
+call.

+Subject: [PATCH] mlxsw: minimal: Add system event handler
+
+Add system event handler for treating line card specific signals on
+modular system. These signals indicate line card state changes, like
+line card activation or de-activation.
+When such signals are received, driver should create or destroy "hwmon"
+"thermal" and module info objects, associated with line card in a slot,
+for which signal has been received.

+Subject: [PATCH] platform: mellanox: Introduce support for next-generation
+ 800GB/s ethernet switch.
+
+Introduce support for Nvidia next-generation 800GB/s ethernet switch - SN5600.
+SN5600 is 51.2 Tbps Ethernet switch based on Nvidia Spectrum-4 ASIC.
+It can provide up to 64x800Gb/s (ETH) full bidirectional bandwidth per port
+using PAM-4 modulations. The system supports 64 Belly to Belly  2x4 OSFP cages.
+The switch was designed to fit standard 2U racks.
+
+Features:
+- 64 OSFP ports support 800GbE - 10GbE speed.
+- Additional 25GbE - 1GbE service port on the front panel.
+- Air-cooled with 3 + 1 redundant fan units.
+- 1 + 1 redundant 3000W or 3600W PSUs.
+- System management board is based on Intel Coffee-lake CPU E-2276
+  with secure-boot support.

+Subject: [PATCH] teamd: lacp: set port to disabled state during removal
+
+Currently, the disabled state is set only after port is removed from
+team master in kernel. Team driver puts the port netdevice down right
+away. In some cases, there is nice to send LACPDU to the partner with
+flags set accordingly for the disabled port.
+
+Introduce "port_removing" op and call it right before kernel
+is asked to remove the port. Implement the op in LACP runner
+to disable the port which leads to proper LACPDU send.
