When PF establishes a connection with Switch Manager, it receives
a logic port range from SM, and registers certain logic ports from
that range, then a default VID will be send back from SM. This whole
transaction needs to be finished in dev_init, otherwise, in dev_start
the interrupt setting will be changed according to RX queue number,
and probably will cause this transaction failed.
