2010-10-11wl1251: create a copy of wl12xx_80211.h for wl1251Kalle Valo
In preparation of moving wl1251 out from drivers/net/wireless/wl12xx create a separate copy of wl12xx_80211.h. This file should not even exist, we should instead use generic ieee80211 definitions. This will be fixed in the future so that the file can be removed. Signed-off-by: Kalle Valo <kvalo@adurom.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-11carl9170: A-MPDU frame type filterChristian Lamparter
In the past, carl9170 has been plagued by mysterious ghosts. e.g.: wlan4: deauthenticated from 02:04:d8:3c:ac:c1 (Reason: 0) Apparently, the AP sent us a bogus deauthentication notification. But upon closer inspection the "management frame" turned out to be a corrupted scrap of an unsuccessful A-MPDU. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.

2010-10-11carl9170: remove stale rx error pathChristian Lamparter
The total/fatal error bit was erroneously prefixed with AR9170_RX_ERROR instead of AR9170_RX_STATUS. Luckily, the hardware specification confirmed that the 0x80 flag will never be set for mac->error. So, it was always just a dead branch. This patch also imports the latest version of shared wlan.h header from the firmware git.

2010-10-11mac80211: Update mesh constants to approved IEEE ANA valuesSteve deRosier
This patch updates IEEE802.11 mesh constants to be consistent with newly approved values. It modifies some values, as well as adds many new constants in preparation for updating mesh code to the current 802.11s drafts. ANA numbers were taken from: https://mentor.ieee.org/802.11/dcn/09/11-09-0031-12-0000-ana-database-assigned-number-authority.xls A few notes are in order: 1. This will break backwards compatibility with existing Linux kernels as over-the-air constants have changed. 2. Some old and obsolete constants have been retained for now as the mesh code itself hasn't been updated yet to the new 802.11s draft. This was desired to keep the existing mesh scheme working until it can be updated. Adding the approved values is the first step in updating the mesh code. 3. Obsolete constants have been clearly marked. 4. All ANA approved 802.11s constants have been added. Signed-off-by: Steve deRosier <steve@cozybit.com> Signed-off-by: John W.

2010-10-11ath9k: implement channel utilization stats for surveyFelix Fietkau
Results for the active channel are updated whenever a new survey dump is requested, the old data is kept to allow multiple processes to make their own channel utilization averages. All other channels only contain the data for the last time that the hardware was on the channel, i.e. the last scan result or other off-channel activity. Running a background scan does not clear the data for the active channel. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-10-11Revert "wireless: Use first phyX name available when registering phy devices."Johannes Berg
This reverts commit 5a254ffe3ffdfa84fe076009bd8e88da412180d2. The commit failed to take into account that allocated wireless devices (wiphys) are not added into the device list upon allocation, but only when they are registered. Therefore, it opened up a race between allocating and registering a name, so that if two processes allocate and register concurrently ("alloc, alloc, register, register" rather than "alloc, register, alloc, register") the code will attempt to use the same name twice.

2010-10-07iwlagn: add temperature offset calib for 6000g2Shanyu Zhao
6000g2 devices need to have temperature offset calibration. The runtime uCode needs to receive the calibration results just like BB and LO calibration.

2010-10-07iwlagn: fix default calibration table sizeShanyu Zhao
iwlagn driver uses the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as the chain noise reset calibration index and IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE+1 as the chain noise gain calibration index, if not specified by the TLV value in the new firmware format. However, this is broken if we need to add more calibrations like the temperature offset calibration because we increased IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE by 1. To fix this issue, define IWL_DEFAULT_STANDARD_PHY_CALIBRATE_TBL_SIZE and use it as the calibration index instead. We still keep the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as a sanity check for the TLV value given by ucode.
