#### 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 - [X] 202012 #### Description for the changelog Support new SKU under the name of SN2700-D40C8S8
