My apologies. Now that it's established that this problem is
specific to the "ath" driver, and not to more general FreeBSD
networking code, I'll restrict future postings to "freebsd-mobile" only.

I've seen the problem happen on two different machines, with two
different interface cards (although both with Atheros chipsets):
Machine1:
%dmesg | fgrep ath

No, unfortunately there's nothing specific that seems to reproduce
this - just some communication to and/or from a remote client.

If there's anything specific that I can run (at the time I see the
problem) that may help identify the problem, please let me know.
Thanks for taking the time to look into this.
