2011-02-14p54: sort channel list by frequency instead of channel indexChristian Lamparter
Some channel indices of the low 5GHz band clash with those of the 2.4GHz band. Therefore we should go with the channel's center frequency. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-02-14zd1211rw: move async iowrite16v up to callersJussi Kivilinna
Writing beacon to device happen through multiple write command calls. zd_usb_iowrite16v uses synchronous urb call and with multiple write commands in row causes high CPU usage. Make asynchronous zd_usb_iowrite16v_async available outside zd_usb.c and use where possible. This lower CPU usage from ~10% to ~2% on Intel Atom when running AP-mode with 100 TU beacon interval.

2011-02-14zd1211rw: use async urb for write commandJussi Kivilinna
Writing beacon to device happen through multiple write command calls. zd_usb_iowrite16v uses synchronous urb call and with multiple write commands in row causes high CPU usage. This patch makes zd_usb_iowrite16v use asynchronous urb submit within zd_usb.c. zd_usb_iowrite16v_async_start is used to initiate writing multiple commands to device using zd_usb_iowrite16v_async. Each URB is delayed and submitted to device by next zd_usb_iowrite16v_async call or by call to zd_usb_iowrite16v_async_end. URBs submitted by zd_usb_iowrite16v_async have URB_NO_INTERRUPT set and last URB send by zd_usb_iowrite16v_async_end does not. This lower CPU usage when doing writes that require multiple URBs.

2011-02-14zd1211rw: correct use of usb_bulk_msg on interrupt endpointsJussi Kivilinna
zd1211rw is using usb_bulk_msg() with usb_sndbulkpipe() on interrupt endpoint. However usb_bulk_msg() internally corrects this and makes interrupt URB. It's better to change usb_bulk_msgs in zd1211rw to usb_interrupt_msg for less confusion. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W.

2011-02-08Bluetooth: ath3k: Avoid duplication of codeRogério Brito
In commit 86e09287e4f8c81831b4d4118a48597565f0d21b, to reduce memory usage, the functions of the ath3k module were rewritten to release the firmware blob after it has been loaded (successfully or not). The resuting code has some redundancy and the compiler can potentially produce better code if we omit a function call that is unconditionally executed in ,---- | if (ath3k_load_firmware(udev, firmware)) { | release_firmware(firmware); | return -EIO; | } | release_firmware(firmware); | | return 0; | } `---- It may also be argued that the rewritten code becomes easier to read, and also to see the code coverage of the snippet in question.

2011-02-04ath9k: add additional checks for the baseband hang detectionFelix Fietkau
Since even with the latest changes the false positive issue of the baseband hang check is not fully solved yet, additional checks are needed. If the baseband hang occurs, the rx_clear signal will be stuck to high, so we can use the cycle counters to confirm it. With this patch, a hardware reset is only triggered if the baseband hang check returned true three times in a row, with a beacon interval between each check and if the busy time was also 99% or more during the check intervals.

2011-02-04ath: Fix clearing of secondary key cache entry for TKIPJouni Malinen
All register writes to the key cache have to be done in pairs. However, the clearing of a separate MIC entry with hardware revisions that use combined MIC key layout did not do that with one of the registers. Add the matching register write to the following register to make the KEY4 register write actually complete. This is mostly a fix for a theoretical issue since the incorrect entry that could potentially be left behind in the key cache would not match with received frames. Anyway, better make this code clean the entry correctly using paired register writes. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-02-04zd1211rw: batch beacon config commands togetherJussi Kivilinna
Beacon config function writes beacon to hw one write per byte. This is very slow (usually taking more than 100ms to finish) and causes high CPU usage when in AP-mode (kworker at ~50% on Intel Atom N270).

2011-02-04zd1211rw: add beacon watchdog and setting HW beacon more failsafeJussi Kivilinna
When doing tx/rx at high packet rate (for example simply using ping -f), device starts to fail to respond to control messages. On non-AP modes this only causes problems for LED updating code but when we are running in AP-mode we are writing new beacon to HW usually every 100ms. Now if control message fails in HW beacon setup, device lock is kept locked and beacon data partially written. This can and usually does cause: 1. HW beacon setup fail now on, as driver cannot acquire device lock. 2. Beacon-done interrupt stop working as device has incomplete beacon. Therefore make zd_mac_config_beacon() always try to release device lock and add beacon watchdog to restart beaconing when stall is detected. Also fix zd_mac_config_beacon() try acquiring device lock for max 500ms, as what old code appeared to be trying to do using loop and msleep(1).

This causes tx-packet to be passed back to upper layer after next packet has been transfered and tx-packets might end up coming come out of monitor interface in wrong order vs. rx. Because of this when enable AP-mode, hostapd monitor interface would get packets in wrong order causing problems in WPA association. So don't use mac->ack_pending when in AP-mode.
