Why I did it

Add new SKU for SN2700 Mellanox system that supports the following port configuration:
8 X 100G
40 X 50G
8 X 10G

How I did it

Add new Folder - "Mellanox-SN2700-D40C8S8" under /sonic-buildimage/device/mellanox/x86_64-mlnx_msn2700-r0/
that contains the relevant files supporting this SKU

the buffers are based on SKU: D48C8 . Later on it will be configured specific for this SKU

How to verify it

Bring up the image, run "show interface status" and make sure that all ports are up and reflect the following requirement:
Port 1/3 will be used as 4x10G
Port 2/4 - Not exist (blocked since 1 and 3 split to 4)
Port 7/8/9/10/23/24/25/26 will used as 100G
All other ports will be used as 2x50G

Which release branch to backport (provide reason below if selected)

  • 201811
  • 201911
  • 202006
  • 202012

Description for the changelog

Support new SKU under the name of SN2700-D40C8S8
