lpfc: Fix the FLOGI discovery logic to comply with T11 standards
Fix the FLOGI discovery logic to comply with T11 standards
We weren't properly setting fabric parameters, such as R_A_TOV and E_D_TOV,
when we registered the vfi object in default configs and pt2pt configs.
Revise to now pass service params with the values to the firmware and
ensure they are reset on link bounce. Required reworking the call sequence
in the discovery threads.
