* [intfsorch] Enable ipv6 proxy ndp along with proxy arp (sonic-net#3045)

* [intfsorch] Enable ipv6 proxy ndp along with proxy arp

setting SAI_VLAN_ATTR_UNKNOWN_MULTICAST_FLOOD_CONTROL_TYPE to
SAI_VLAN_FLOOD_CONTROL_TYPE_NONE when proxy arp is enabled. This fixes a
bug where ipv6 NS packets were flooding ports with duplicate packets. We
now set multicast flood type to none.

* Fix multi VLAN neighbor learning (sonic-net#3049)

What I did

When adding a new neighbor, check if the neighbor IP has already been learned on a different VLAN. If it has, remove the old neighbor entry before adding the new one.

Why I did it
On Gemini devices, if a neighbor IP moves from an active port in one VLAN to a second VLAN, then back to the first VLAN (with 3 different MAC addresses), orchagent will crash. Even though the MAC address of the last move is different from the first MAC address, orchagent believes the last MAC address to already be programmed in the hardware and tries to set an attribute of the entry which doesn't exist.

* Add basic fabric link monitoring counters and states handling.

* [Mellanox] Fix inconsistence in the shared headroom pool initialization (sonic-net#3057)

* Fix inconsistence in the shared headroom pool initialization

* Why I did it

During initialization, if SHP is enabled

the buffer pool sizes, xoff have initialized to 0, which means SHP is disabled
but the buffer profiles already indicate SHP
later on the buffer pool sizes are updated with off being non-zero
In case the orchagent starts handling buffer configuration between 2 and 3, it is inconsistent between buffer pools and profiles, which fails Mellanox SAI sanity check.
To avoid it, it indicates SHP enabled by setting a very small buffer pool and SHP sizes

* [acl] Add IN_PORTS qualifier for L3 table (sonic-net#3078)

* Apply IN_PORTS qualifiier for L3 table

Why I did it
IN_PORTS qualifier was allowed for L3 table in 202012 release and below. Changes in sonic-net#1982 removed that support leading to regression in some of our testcases. The following error was observed
ERR swss#orchagent: :- validateAclRuleMatch: Match SAI_ACL_ENTRY_ATTR_FIELD_IN_PORTS in rule RULE_1 is not supported by table DATAACL

* [bulker] add support for neighbor bulking (sonic-net#2768)

Adding support for sai_neighbor_api_t bulking in bulker.h

* [buffermgrd] Move switch-statement outside of if-statement in BufferMgr::doTask (sonic-net#3055)

* [buffermgr] Moved switch statement outside of if-statmement in Buffermgr::doTask

The switch statement which would normally erase buffer events was moved
to be inside the if-statement which would only enter if the event is a
SET event. This was introduced in commit e5329c39.

This would cause an infinite loop, since non-set events would never be
erased.

The switch statement has now been moved to occur outside the if,
allowing for non-set commands to be processed.

* [portsorch] process only updated APP_DB fields when port is already   created (sonic-net#3025)

* [portsorch] process only updated APP_DB fields when port is already created

What I did

Fixing an issue when setting some port attribute in APPL_DB triggers serdes parameters to be re-programmed with port toggling. Made portsorch to handle only those attributes that were pushed to APPL_DB, so that serdes programming happens only by xcvrd's request to do so.

* [Copp]Refactor coppmgr tests (sonic-net#3093)

What I did
Refactoring coppmgr mock tests

Why I did it
After migration to bookworm, coppmgr tests started failing due to the use of sudo commands.

* Revert "[acl] Add IN_PORTS qualifier for L3 table (sonic-net#3078)" (sonic-net#3092)

This reverts commit 9d4a3ad.

* [orchagent] TWAMP Light orchagent implementation (sonic-net#2927)

* [orchagent] TWAMP Light orchagent implementation. (sonic-net#2927)
* What I did
Implemented the TWAMP Light feature according to the SONiC TWAMP Light HLD(sonic-net/SONiC#1320).

* Clang format change. (sonic-net#3080)

What I did
This PR has no real code change. It is purely clang formatting. It only applies to the P4Orch codes.
Commands that I run:
find orchagent/p4orch -name *.h -o -name .cpp | xargs clang-format -i -style="{BasedOnStyle: Microsoft, DerivePointerAlignment: false}"

find orchagent -name response_publisher -o -name return_code.h | xargs clang-format -i -style="{BasedOnStyle: Microsoft, DerivePointerAlignment: false}"

* Adding extern_learn flag with fdb entry so that Kernel doesn't age out the MAC

* [Fdbsyncd] Adding extern_learn flag with fdb entry so Kernel doesn't age out

What I did
extern_learn flag is added while programming the fdb entry into the Kernel. This will make sure that kernel doesn't age out the fdb entry. (#15004)

How I did it
A flag extern_learn will be passed while programing the fdb entry. (#15004)

How to verify it
Tested MAC add/del to the Kernel from the local FDB entry. (#15004)

What I did
This PR is to fix sonic-net/sonic-buildimage#18719

When ACL rule is created for the first time, a flex counter is created and registered. When the same ACL rule is being updated, the FlexCounter created before is not removed, and another FlexCounter is created and registered.

Why I did it
Fix the issue that FlexCounter is duplicated when updating existing ACL rule.
