Backporting the IEEE80211_TXQ_STOP_NETIF_TX stuff doesn't seem that problematic either, but I'm not convinced it's worth it, and I suppose somebody whose driver actually uses it on those kernels would better take a look - I'm not familiar with all the drivers in detail, and iwlwifi doesn't use it yet there. johannes
