BUG in ath9k_tx

BUG in ath9k_tx

[Ben Greear]

I am running 2.6.36-rc4-wl+, with Johannes's sta_info_get_bss patch,
my ath9k rxfilter patch, and Felix's bssid-mask patch.

I had created two un-encrypted STA interfaces.  I was messing with another
machine, trying to get a sniffer working when this happened.

I saw this a few days ago as well, but didn't get a chance to get a good
stacktrace.
