2010-06-25iwlwifi: name change from signal protection flagWey-Yi Guy
This bit need to be set for both RTS/CTS or CTS-to-self protection, if CTS-to-self is used, then uCode will check the RXON_FLG_SELF_CTS_EN status. Change the name from TX_CMD_FLG_RTS_CTS_MSK to TX_CMD_FLAG_PROT_REQUIRE_MSK to match the behavior of the bit setting. Also update comments to reflect which hardware uses which of the TX command flags. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>

2010-06-25iwlwifi: set TX_CMD_FLAG_PROT_REQUIRE_MSK in tx_flagWey-Yi Guy
When building tx command, always set TX_CMD_FLAG_PROT_REQUIRE_MSK for 5000 series and up. Without setting this bit the firmware will not examine the RTS/CTS setting and thus not send traffic with the appropriate protection. RTS/CTS is is required for HT traffic in a noisy environment where, without this setting, connections will stall on some hardware as documented in the patch that initially attempted to address this: commit 1152dcc28c66a74b5b3f1a3ede0aa6729bfd48e4 Author: Wey-Yi Guy <wey-yi.w.guy@intel.com> Date: Fri Jan 15 13:42:58 2010 -0800 iwlwifi: Fix throughput stall issue in HT mode for 5000 Similar to 6000 and 1000 series, RTS/CTS is the recommended protection mechanism for 5000 series in HT mode based on the HW design. Using RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment, it also prevent uCode encounter TX FIFO underrun and other HT mode related performance issues. For 3945 and 4965, different flags are used for RTS/CTS or CTS-to-Self protection. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
2010-06-25iwlwifi: fix multicastJohannes Berg
commit 3474ad635db371b0d8d0ee40086f15d223d5b6a4 Author: Johannes Berg <johannes.berg@intel.com> Date: Thu Apr 29 04:43:05 2010 -0700 iwlwifi: apply filter flags directly broke multicast. The reason, it turns out, is that the code previously checked if ALLMULTI _changed_, which the new code no longer did, and normally it _never_ changes. Had somebody changed it manually, the code prior to my patch there would have been broken already. The reason is that we always, unconditionally, ask the device to pass up all multicast frames, but the new code made it depend on ALLMULTI which broke it since now we'd pass up multicast frames depending on the default filter in the device, which isn't necessarily what we want (since we don't program it right now). Fix this by simply not checking allmulti as we have allmulti behaviour enabled already anyway.

In preparation for a TX power setting interface in the nl80211, change the .set_tx_power function to use mBm units instead of dBm for greater accuracy and smaller power levels. Also, already in advance move the tx_power_setting enumeration to nl80211. This change affects the .tx_set_power function prototype. As a result, the corresponding changes are needed to modules using it. These are mac80211, iwmc3200wifi and rndis_wlan.

2010-06-24at76c50x-usb: Extract bssid from authentication frameSebastian Smolorz
The driver at76c50x-usb is unable to authenticate with an AP since kernel 2.6.31 for the following reason: The join command of the firmware needs to be sent with the right bssid before any transmission can start. Before kernel 2.6.31 mac80211 informed its drivers about the changing bssid early enough for at76c50x-usb but during the development of 2.6.31 mac80211's behaviour changed. Now a new bssid is set after the association. This patch changes the tx routine of the driver at76c50x-usb in such a way that a new bssid is extracted from an authentication frame and the join command with that bssid is processed.

2010-06-23ath9k: Fix bug in starting aniVasanthakumar Thiagarajan
There are few places where ANI is started without checking if it is right to start. This might lead to a case where ani timer would be left undeleted and cause improper memory acccess during module unload. This bug is clearly exposed with paprd support where the driver detects tx hang and does a chip reset. During this reset ani is (re)started without checking if it needs to be started. This would leave a timer scheduled even after all the resources are freed and cause a panic. This patch introduces a bit in sc_flags to indicate if ani needs to be started in sw_scan_start() and ath_reset(). This would fix the following panic. This issue is easily seen with ar9003 + paprd.
