Why I did it

Two changes needed in sonic-swss to support 1.6T.

  • The parsePortSpeed and parsePortAdvSpeeds functions validate speeds against min/max values
  • Update FLR calculation for 200G SerDes rate

How I did it

  • Changed max speed to 1.6T
  • Added 200G lane_speed to the FLR calculation

How to verify it

We cannot yet as the hardware does not exist
