* ath9k: make DFS detector pools SMP safeZefir Kurtisi2012-04-23

* rt2x00: Use GFP_KERNEL for rx buffer allocation on USB devicesHelmut Schaa2012-04-23
| | | | | | | | | | | Since the RX path on USB devices is handled in process context we can use GFP_KERNEL for RX buffer allocation. This should reduce the likelihood of allocation failures.

* mac80211: don't set mesh peer ht caps if ht disabledThomas Pedersen2012-04-23
| | | | | | | | | | Blindly setting ht caps on a mesh peer's station entry would result in MCS rates being used by the rate control algorithm even if no ht had been configured.

* mac80211: refactor mesh peer initializationThomas Pedersen2012-04-23
| | | | | | | | | | | | This patch unifies the previous two paths toward mesh peer creation a bit. It also fixes a bug where a peer's changing rates or HT mode wouldn't register on leaving and then returning to the mesh with a sta entry still present. Also clean up locking and clear possibly stale ht cap. Signed-off-by: Thomas Pedersen <thomas@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: fix TX power reporting on AR9003 chipsGabor Juhos2012-04-23
| | | | | | | | | | | | | | | | | | | | | | The current code unconditionally reads the target power values for all modes from the EEPROM. However In 'ar9003_hw_set_power_per_rate_table' the regulatory caps are applied only on a mode specific subset of the power values. The reported TX power level is calculated from the maximum of the power values. Because some of these values are uncapped in certain cases, the reported TX power will be wrong. On the older chipset, we don't have such problems because only the mode specific subset of the power levels are retrieved from the EEPROM on those. Do the same for the AR9003 chips to fix the issue.

The idea is to let users scan on the current operating channel without interrupting normal traffic more than absolutely necessary (changing power level might reset some hardware, for instance).

* iwlwifi: improve TX cache footprintJohannes Berg2012-04-18
| | | | | | | | | | | | | | | | | | Having cmd[], meta[] and skbs[] as separate arrays in the TX queue structure is cache inefficient as we need the data for a given entry together. To improve this, create an array with these three members (allocate meta as part of that struct) so we have the data we need together located together improving cache footprint. The downside is that we need to allocate a lot of memory in one chunk, about 10KiB (on 64-bit) which isn't very efficient.

* mwifiex: corrections in timestamp related codeAmitkumar Karwar2012-04-17
| | | | | | | | | | | | | | | | | | | | | | | | We get two timing related fields for each bss from firmware in scan results. 1) timestamp - Actual timestamp information in probe response/beacon 2) network_tsf - firmware's TSF value at the time the beacon or probe response was received. Both are needed while associating by firmware. The patch takes care of following things. 1) We should pass "timestamp" to cfg80211_inform_bss(), but currently "network_tsf" is being provided. This error is corrected here. 2) Rename "network_tsf" to "fw_tsf" 3) Make use of u64 variable instead of an array of u8/u32 to save parsed "timestamp" information. 4) Use timestamp provided to stack in scan results using cfg80211_inform_bss() while associating. (bss->tsf) 5) Allocate space to save fw_tsf in "priv" of cfg80211_bss and retrieve it while associating.

| | | | | | | | | | | | | | | | | | As described at http://article.gmane.org/gmane.linux.kernel.wireless.general/86084 libertas is taking a long time to load because it loads firmware during module loading.

Remove the ability to reprogram internal device memory with a different firmware from the USB driver (we don't know of any users), and simplify the OLPC firmware loading quirk to simply placing the OLPC firmware at the top of the list (we don't know of any users other than OLPC). Move lbs_get_firmware() into its own file. These simplifications should have no real-life effect but make the upcoming transition to asynchronous firmware loading considerably less painful.

* rt2x00: Don't let mac80211 send a BAR when an AMPDU subframe failsAndreas Hartmann2012-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are connection stalls or very poor throughputs with rt2800 hardware using 802.11n in AP mode since patch "mac80211: retry sending failed BAR frames later instead of tearing down aggr"[1][2]. Since rt2800 hardware is not able to correctly report the tx status of BAR frames, this patch removes as workaround the existing error handling on AP side, which lets mac80211 send a BAR when an AMPDU subframe fails. As a result, most wifi clients (aside from Intel STAs on Windows) instead will timeout now the reorder buffer and request the lost frame again. The correct solution would be, to tear down BA session on AP side. This patch was born on the basis of "[RFT] rt2x00: Tear down BA session on QoS frame failure"[3]. Thanks to Helmut Schaa for his support!
