which platform does this affect?

Sorry I missed this question earlier. These changes specifically target the Arista 7800r3a* linecards; e.g.,

• x86_64-arista_7800r3a_36d2_lc
• x86_64-arista_7800r3a_36d_lc
• x86_64-arista_7800r3a_36dm2_lc
• x86_64-arista_7800r3a_36p_lc
• x86_64-arista_7800r3ak_36d2_lc
• x86_64-arista_7800r3ak_36dm2_lc

@arlakshm , can you check if this is needed?

@lguohan and @arlakshm these changes are necessary for the Wolverine line cards to address some race conditions with fabric initialization as well corner cases during transceiver insertions. Let us know if you have any additional questions.

@lguohan @yxieca, can you help merge this PR. This is needed for chassis

[yxieca]

@kenneth-arista does this change affect any platform other than 7800? @arlakshm can you assess if we can take this change to chassis branch only?

[kenneth-arista]

We can close this PR in favor of merging #19338 instead
