Has anybody else seen if_rum die when you try to transmit a file over
a TCP connection ?

If I try to print across the network, upload a file with ftp or anything
else of that general tenor, if_rum seems to hang the output queue and
stops transmitting packets.

Restarting wpa_supplicant mostly resolves the issue, but it does not
on its own discover the problem.

According to tcpdump(8), packets are still received.

Any ideas ?
