p54: redo rx_status into skb->cb

mac80211: push rx status into skb->cb

2009-07-10T18:57:54+00:00

Within mac80211, we often need to copy the rx status into skb->cb. This is wasteful, as drivers could be building it in there to start with. This patch changes the API so that drivers are expected to pass the RX status in skb->cb, now accessible as IEEE80211_SKB_RXCB(skb). It also updates all drivers to pass the rx status in there, but only by making them memcpy() it into place before the call to the receive function (ieee80211_rx(_irqsafe)). Each driver can now be optimised on its own schedule. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

p54: tx refused but queue active

2009-07-08T19:24:30+00:00

In the mainline kernel, p54usb will fail because the TX queue length can become < 0. This problem has been reported as Bugzilla #13725. The failure is expressed by the following message in the logs: WARNING: at net/mac80211/tx.c:1325 ieee80211_tx+0x23c/0x298 [mac80211]() Hardware name: HP Pavilion dv2700 Notebook PC tx refused but queue active This problem has been recently observed in the wireless-testing tree, where a full solution is being tested. That fix is too invasive for 2.6.31-rcX, but the simple change supplied here will prevent the failure. Signed-off-by: Larry Finger Signed-off-by: John W. Linville

p54: call p54_wake_free_queues on every p54_free_skb and p54_rx_frame_sent

2009-05-06T19:15:05+00:00

Currently queues are stopped when their length reaches their length limit, but are restarted only when the size of freed range of packet buffer is not less than the size of the largest possible packet. This causes permanent queue stop on radio visibility loss in the middle of ping series: there is plenty of room in the packet buffer, but it is never freed more than 3 (size of 'best effort' queue) * 288 (ping packet plus headers) bytes at once.

mac80211: unify config_interface and bss_info_changed

2009-05-06T19:14:36+00:00

The config_interface method is a little strange, it contains the BSSID and beacon updates, while bss_info_changed contains most other BSS information for each interface. This patch removes config_interface and rolls all the information it previously passed to drivers into bss_info_changed. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

p54: fix ps-poll delivery in ap mode

p54: deactivate broken powersave function (part 2)

2009-04-22T20:57:15+00:00

This patch deactivates powersave in station mode. It does not work correctly yet, so the code does more harm than good. (I split the original patch and sent part of it for 2.6.30, which didn't have the IEEE80211_HW_BEACON_FILTER flag. -- JWL) Reported-by: Johannes Berg Signed-off-by: Christian Lamparter Signed-off-by: John W.
