[Arista] [201811] Add Arista-7260CX3-D96C16 HWSKU (#10034)
Browse files Browse the repository at this point in the history 
Why I did it
This was an ask by Microsoft to provide:
7260 config.bcm file for hardware sku Arista-7260CX3-D92C16 (Named Arista-7260CX3-D96C16).

There are 16 100G uplinks:
Ethernet13-20/1
Ethernet45-52/1

All other ports are breakout to 2 50G ports.

How I did it
Copied existing Arista-7260CX3-D108C8 HWSKU and altered the bcm.config and port_config.ini files.

How to verify it
The new 100G ports do come up with a 201811 image using this HWSKU.
