And we do not know if we will ever receive the frame. Hence we cannot re-use the xid as we would risk data corruption if the xid had been re-used and the timed out frame would be received after that. So we need to quarantine the xid until the lport is reset. Yes, I know this will (eventually) deplete the xid pool. But for now it's the safest method.
