Why I did it

This PR is to add buffer configurations for 3 Arista-7060x6 HWSKUs

  • Arista-7060X6-64PE-O128S2
  • Arista-7060X6-64PE-P32O64
  • Arista-7060X6-64PE

Different buffer configuration files are loaded for different roles

  • buffers_default_lt2.json if subtype == lowerspinerouter
  • buffers_default_ft2.json is type == fabricspinerouter
Work item tracking
  • Microsoft ADO 32548218

How I did it

  1. Add new configuration files
  2. Select right file according to device type and subtype

How to verify it

Change is verified on a physical testbed by generating buffer configurations.
