Approach What is the motivation for this PR? After config mux state active EthernetXX, the first toggle might not be able to be succeeded as xcvrd has a chance to fail to setup the gRPC connection as the route changed by muxorch needs time to work. Signed-off-by: Longxiang Lyu lolv@microsoft.com How did you do it? The state change sequence after linkmgrd boots up and receives a mux config active: (unknown, unknown, up) --> config mux active --> (unknown, active, up) --> mux state unknown[as xcvrd could not setup gRPC connection] --> (unknown, unknown, up) --> probe mux state, return unknown --> (unknown, unknown, up) Once linkmgrd reaches (unknown, unknown, up), it will keep probing the mux till xcvrd returns either active or standby: if the probe result is active, we need an extra toggle to active to let show mux status shows active. if the probe result is standby, we also need an extra toggle to active to notify the gRPC server the port is standby and let show mux status shows active. How did you verify/test it?

After
config mux state active EthernetXX, the first toggle might not be able to be succeeded asxcvrdhas a chance to fail to setup the gRPC connection as the route changed bymuxorchneeds time to work.Signed-off-by: Longxiang Lyu lolv@microsoft.com
How did you do it?
The state change sequence after
linkmgrdboots up and receives a mux config active:(unknown, unknown, up) --> config mux active --> (unknown, active, up) --> mux state unknown[as xcvrd could not setup gRPC connection] --> (unknown, unknown, up) --> probe mux state, return unknown --> (unknown, unknown, up)
Once
linkmgrdreaches (unknown, unknown, up), it will keep probing the mux tillxcvrdreturns either active or standby:if the probe result is active, we need an extra toggle to active to let
show mux statusshows active.if the probe result is standby, we also need an extra toggle to active to notify the gRPC server the port is standby and let
show mux statusshows active.How did you verify/test it?
Any platform specific information?
