2010-02-08mac80211_hwsim: add fake hw scan handlerJohannes Berg
For debugging hardware scan trigger/complete functionality, it was useful to have code in hwsim that pretends to do a hardware scan. This code could be extended to actually do the scan, but for now it was sufficient for me to only pretend. Since hwsim was written to ease debugging, it only makes sense to add it to it permanently.

2010-02-03b43: Fix throughput regressionLarry Finger
Commit c7ab5ef9bcd281135c21b4732c9be779585181be entitled "b43: implement short slot and basic rate handling" reduced the transmit throughput for my BCM4311 device from 18 Mb/s to 0.7 Mb/s. The basic rate handling portion is OK, the problem is in the short slot handling. Prior to this change, the short slot enable/disable routines were never called. Experimentation showed that the critical part was changing the value at offset 0x0010 in the shared memory. This is supposed to contain the 802.11 Slot Time in usec, but if it is changed from its initial value of zero, performance is destroyed. On the other hand, changing the value in the MMIO register corresponding to the Interframe Slot Time increased performance from 18 to 22 Mb/s. A BCM4306/3 also shows dramatic improvement of the transmit rate from 5.3 to 19.0 Mb/s. Other changes in the patch include removal of the magic number for the MMIO register, and allowing the slot time to be set for any PHY operating in the 2.4 GHz band. Previously, the routine was executed only for G PHYs.

2010-01-25b43: Workaround circular locking in hw-tkip key update callbackMichael Buesch
The TKIP key update callback is called from the RX path, where the driver mutex is already locked. This results in a circular locking bug. Avoid this by removing the lock. Johannes noted that there is a separate bug: The callback still breaks on SDIO hardware, because SDIO hardware access needs to sleep, but we are not allowed to sleep in the callback due to mac80211's RCU locking.

ath9k currently forces hw->max_rate_tries to 4 to work around rate control inefficiencies. This has some negative side effects, such as rate_control_send_low also using a maximum of 4 tries, which could negatively affect reliability of unicast management frames.

The aggregation (and possibly other) station flags were not being set, which limited the size of aggregation blocks and reduced throughput at high rates. >From Johannes: """ Due to Wey-Yi's patch to use the set-channel command when the channel changes while associated, we don't get a full new RXON. Therefore, we don't re-set the rxon-station either. However, under some circumstances that apparently have gotten more likely mac80211 will first set up the BSS info, then add the station and then switch to an HT channel type. Therefore, the check for "priv->current_ht_config.is_ht" in iwl_rxon_add_station() will hit false and not fill in the HT information. However, that check can just be removed, which is the easiest fix for all this, because the HT capa struct is always there, just could possibly have the ht_supported member set to false.

2010-01-25iwlwifi: cleanup spectrum measurement command supportReinette Chatre
In iwlagn the support for spectrum measurement command has been disabled since v2.6.29 without any requests for it. In addition to this when this command is indeed enabled it has been found to trigger firmware SYSASSERT on at least 4965 and 5100 hardware (see http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1952 ). Since then this code has been bitrotting and cannot just be enabled without porting. Remove support for spectrum measurement command from iwlagn. It can be added back if there is a future need and the firmware problem it triggers has been fixed. Support for the spectrim measurement notification remains as it has been enabled all the time. In addition to this remove the 3945 spectrum measurement command Kconfig option and make this command always supported. The code added by this enabling is minimal and only run when user triggers a spectrum measurement request via sysfs. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
