Um... yes, that would probably work. But it's subtle enough that it
bothers me. And if it *did* cause any strange issues, it's a rare case
and would be hard to reproduce/debug. Is it *really* necessary, just to
speed up the vcc close? I'm inclined to stick with the 'KISS' approach.
(Note that the card->tx_skb[port] skb isn't on the queue any more; you'd
do that bit separately and not in the skb_queue_walk() loop.)
