[PATCH net-next 13/15] net/mlx5: E-Switch, defer rep load while SD LAG is not active

[Tariq Toukan]

From: Shay Drory <shayd@xxxxxxxxxx>

On an SD device, vport representors are not functional until the SD
group is combined and shared FDB is active. Skip both the initial load
and the reload path in that window; reps are loaded as part of the SD
LAG activation flow once it becomes active.
