2009-05-28p54: Use SKB list handling helpers instead of by-hand code.David S. Miller

2009-05-06p54: call p54_wake_free_queues on every p54_free_skb and p54_rx_frame_sentMax Filippov
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.

2009-05-06mac80211: unify config_interface and bss_info_changedJohannes Berg
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.

2009-04-22p54: fix ps-poll delivery in ap modeChristian Lamparter
PS-Polled frames must be sent with OUT_NOCANCEL flag set, or the firmware will reject all of them, at the station is still blacklisted. Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-04-22p54: deactivate broken powersave function (part 2)Christian Lamparter
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 <johannes@sipsolutions.net> Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W.

2009-04-22p54: utilize all available key slots for decryption offloadChristian Lamparter
This patch takes care of outstanding TODOs: /* TODO: some devices have 4 more free slots for rx keys */ Now the driver can utilize all available key slots instead of just 4. Obviously, this helps most in AP/IBSS(/MESH) mode, when we have to use more different keys. Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W.

2009-04-22p54: more SoftLED updatesChristian Lamparter
This patch hopefully finishes the SoftLED code: - It adds two more LEDs (rx and radio). (the FW claims it can support up to 16 LEDs, but I doubt that any vendor put more than 4 on a board) - update the LEDs in a _delayed_ workqueue. No one reported any more crashes. (see: "PATCH] p54: fix race condition in memory management") So we can stop burning the mm code.

2009-03-16p54: fix iwconfig txpower offChristian Lamparter
Disabling the receiver logic with P54_FILTER_TYPE_RX_DISABLED is not supported by all firmwares. However we have an alternative: hibernation.

2009-01-29p54: upgrade memrecord to p54_tx_infoChristian Lamparter
mac80211 reserves 24 bytes in skb->cb for the driver. So far, we only used them to keep track of used and free device memory. But p54spi will need a slice of it, as well as the stuck frame detection.

2009-01-29p54: refactor p54_alloc_skbChristian Lamparter
Old firmwares had no problems processing frames which filled eighth of the memory window. However we have to be a bit more careful with fat frames when we talk to new firmwares. Apart from that, I confess the old logic was a bit weird and not very sophisticated. Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
