2011-04-28wl12xx: support FW TX inactivity triggersArik Nemtsov
In AP mode we register for the MAX_TX_RETRY and INACTIVE_STA events. Both are reported to the upper layers as a TX failure in the offending stations. In STA mode we register only for the MAX_TX_RETRY event. A TX failure is interpreted as a loss of connection. Support for IEEE80211_HW_REPORTS_TX_ACK_STATUS has been removed to avoid the inherent race condition of a mac80211 TX failure counter in addition to the FW counter.

2011-04-26cfg80211: fix regresion on reg user timeoutLuis R. Rodriguez
The patch "cfg80211: add a timer for invalid user reg hints" introduced a regression for the case where a secondary identical regulatory hint from a user is sent. What would happen is the second hint would schedule delayed work in to catch a timeout but since we are never processing it given that the hint was already applied we'd always hit the timeout and and restore regulatory settings back to world regulatory domain. This is fixed by simply avoiding sheduling work if the hint was already applied. Tested-by: Felix Fietkau <nbd@openwrt.org> Reported-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Luis R.

2011-04-26p54: implement multicast filterChristian Lamparter
"For best CPU usage and power consumption, having as few frames as possible percolate through the stack is desirable. Hence, the hardware should filter as much as possible." Note: Not all firmwares include the multicast filter feature and the stack does not filter them either. The ARP filter on the other hand was dropped from the patch since it does not work correctly: Quote from: Max Filippov <jcmvbkbc@gmail.com> <http://www.spinics.net/lists/linux-wireless/msg67466.html> "In the ARP case, when there's no other traffic on p54spi, all ARP requests are dropped. But if there's some egress traffic from p54spi, filter seems to work correctly: only ARP requests that match filter pass through. In the multicast case filter seems to work correctly, but it treats broadcast as subject to that filtering too. By default only 01:00:5e:00:00:01 gets into priv->mc_maclist, so we miss all broadcasts. These two filters seem to interfere: - if we set ARP filter and multicast filter without bc => we miss all ARPs if there's no egress traffic; - if we set ARP filter and multicast filter with bc or don't set mc filter at all => we get all ARPs. This effect does not depend on filter setup order." Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Tested-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: John W.

2011-04-26ath9k_hw: Fix Tx IQ Calibration hang issue in AR9003 chipsRajkumar Manoharan
On AR9003 chips, doing three IQ calibrations will possibly cause chip in stuck state. In noisy environment, chip could receive a packet during the middle of three calibrations and it causes the conflict of HW access and the eventual failure. It also causes IQ calibration outliers which results in poor Tx EVM. The IQ Cal procedure is after resetting the chip, run IQ cal 3 times per each cal cycle and find the two closest readings and average of two. The advantage of running Tx IQ cal more than once is that we can compare calibration results for the same gain setting over multiple iterations. Most of the cases the IQ failures were observed after first pass. For the AR9485 and later chips, Tx IQ Calibration is performed along with AGC cal. But for pre-AR9485 chips, Tx IQ cal HW has to be separated from the rest of calibration HW to avoid chip hang. After all calibrations are done in HW, we can start SW post-processing. By doing this way, we minimize the SW difference among all chips. The order of calibration (run IQ cal before other calibration) is also needed to avoid chip hang for chips before AR9485. This issue was originally observed with AR9382. During the issue kernel log was filled with following message ath: timeout (100000 us) on reg 0xa640: 0x00000001 & 0x00000001 != 0x00000000 ath: timeout (100000 us) on reg 0xa2c4: 0x00158dd9 & 0x00000001 != 0x00000000 ath: Unable to reset channel (2412 MHz), reset status -5 ath: Unable to set channel Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.
