Why I did it

Upgrade the xgs SAI version on 202511 to 14.3.0.0.0.0.21.0 (17.0 and 18.0 are subsumed by 19.0):

  • 14.3.0.0.0.0.19.0: TH6C-B1 SDK fixes (also folds in 17.0 + 18.0 incremental fixes)
  • 14.3.0.0.0.0.20.0: CSP CS00012458649 â�� Uplift SDK-457303 to SAI 14.3
  • 14.3.0.0.0.0.21.0: Uplift SONIC-123420 â�� Lots of RX Signal Detect Invalid Port ERRs throughout operation (matches CSP CS00012461973)
Work item tracking
  • Microsoft ADO (number only): 38131319
