I don't think this patch will work. When a beacon is updated and we then send out multicast frames it's typically been quite a while since the beacon was sent which can be quite bad for PS stations. I tried something like this once and it didn't really work at all, ARP requests went unanswered pretty much. > Looking at Johannes's docs, I don't see anything that seems > to relate to "implement sequence numbering for frames with the > IEEE80211_TX_CTL_ASSIGN_SEQ flag (or ask the hardware to do it for > those frames)". Anyone know how to ask the hardware to do that? It does that, but for legacy reasons iwlwifi makes it depend on whether the frame is QoS or not without checking the flag. It also assigns its own seqnos to qos frames ... > I also don't see anything for "When sending probe response frames, > the timestamp must be adjusted by the hardware or firmware." But, > I didn't look too hard -- maybe I missed it? That is normally not required to be programmed specifically, but I don't know in this case. johannes PS: you sent this patch as linville@xxxxxxxxxxxxxxxxxx
