fnic_set_port_id() - set the port_ID after successful FLOGI. : local port. : assigned FC_ID. : received frame containing the FLOGI accept or NULL.

This is called from libfc when a new FC_ID has been assigned. This causes us to reset the firmware to FC_MODE and setup the new MAC address and FC_ID.

It is also called with FC_ID 0 when we're logged off.

If the FC_ID is due to point-to-point, fp may be NULL.
