We started testing with two AR9380 NICs today (one AP, the other STA).
I applied Felix's skb optimization patch, and the ath9k memleak fix patch
on top of 3.3.7+.
The system has 2GB RAM, but it is 32-bit kernel, so not all
is available to the networking code... That said, the OOM
killer kills VNC and such.
Anyway, I'll try some memleak debugging to see if
I can find any leaks. It seems to me that we should
not actually OOM just by trying to transmit too fast
on a station interface :P
well, there's that:

It might not fix the bug, but it can save you time to confirm
that is not related to this particular skb leak.
Ok, I will try this.
The leak this might fix is some ack logic up in mac80211?
Seems like we could also use some atomic counters to keep
track of number of outstanding mac80211-alocated skbs with this
and be worried if this number grows and grows?
Thanks,
Ben
