Ok looked a bit more at this. I don't see a leak, but I think the
txbufs aren't getting reaped. Otherwise, we should reenable the queues
when we get back 40 TX completion interrupts.
I'm a bit short on time to track it down, but one thing to try is
commenting out the following from ath5k_beacon_send (will break buffering
but you can test non-ps clients):
skb = ieee80211_get_buffered_bc(sc->hw, sc->vif);
while (skb) {
ath5k_tx_queue(sc->hw, skb, sc->cabq);
skb = ieee80211_get_buffered_bc(sc->hw, sc->vif);
}
