2011-08-24ath9k: Fix rx overrun interrupt stormRajkumar Manoharan
Whenever RXEOL is received, both RXORN and RXEOL got cleared to avoid rx overrun interrupt storm. This was handled only for edma chips. The same scenario was also observered with AR9280, doing frequent channel type switch b/w HT20/40 with bidi traffic that is causing failure to stop rx dma. This patch clears the RXEOL & RXORN interrupts for all chips. ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 DMADBG_7=0x000062c0 ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath9k/recv.c:532 ath_stoprecv+0x110/0x120 [ath9k]() Call Trace: [<ffffffff8104a55a>] warn_slowpath_common+0x7a/0xb0 [<ffffffff8104a5a5>] warn_slowpath_null+0x15/0x20 [<ffffffffa0560380>] ath_stoprecv+0x110/0x120 [ath9k] [<ffffffffa055e6fa>] ath_reset+0x6a/0x200 [ath9k] Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

2011-08-24ath9k_hw: Fix exceed transmission burst-time of 5GHzRajkumar Manoharan
The WAR which adds extra delimiters when using RTS/CTS with aggregation and non-enterprise AR9003 chips. This extra padding is done after doing all the 4ms limit checks and hence the total aggregate sizes are exceeding the allowed duration.

2011-08-22mwl8k: Traffic to clients gets affected when one client leaves a cyrpto bssNishant Sarmukadam
When a client disassociates from a crypto enabled bss, data traffic to other clients connected to the bss is stalled. This was due to a boolean variable used to keep track if HW crypto is enabled i.e. if set key has been called to add a key. This flag was being reset every time delete key was called e.g when a station leaves the bss. Once the flag is reset, rx status flags were not being set for connected clients which disrupts traffic to these clients. Fix this issue by not resetting the flag since we do not need to reset this flag during the life time of the bss. Signed-off-by: Nishant Sarmukadam <nishants@marvell.com> Signed-off-by: John W.

b43_op_config and b43_op_bss_info_changed apply many settings by directly writing to hardware registers. These settings are lost as soon as the core is restarted and the initvals are reloaded.

2011-08-12ath9k: avoid sending a-mpdu packets to sleeping stationsFelix Fietkau

2011-08-12ath9k: remove eeprom txgain override for minor version < 19Marek Lindner
ath9k_hw_4k_get_eeprom() overrides the eeprom value for txgain if the minor version is not 19 or above with a value of 0. ar9002_hw_init_mode_gain_regs() relies on this information to determine whether this is a high power wifi card or not. The override caused the driver to always use the 'normal' power tables even for high power devices if their minor version was not high enough. Thus leading to reduced power output. This isn't needed for the AR9285; the check originated with the AR9280 setup code which requires the EEPROM version check.

2011-08-09rt2x00: Fix PCI interrupt processing race on SMP systemsHelmut Schaa
When toggle_irq is called for PCI devices to disable device interrupts it used tasklet_disable to wait for a possibly running tasklet to finish. However, on SMP systems the tasklet might still be scheduled on another CPU. Instead, use tasklet_kill to ensure that all scheduled tasklets are finished before returning from toggle_irq. Furthermore, it was possible that a tasklet reenabled its interrupt even though interrupts have been disabled already. Fix this by checking the DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts during tasklet processing. While at it also enable/kill the TBTT and PRETBTT tasklets in the toggle_irq callback and only use tasklet_kill in stop_queue to wait for a currently scheduled beacon update before returning.

2011-08-09libertas: disable functionality when interface is downDaniel Drake
Modify the driver so that it does not function when the interface is down, in preparation for runtime power management. No commands can be run while the interface is down, so the ndo_dev_stop routine now directly does all necessary work (including asking the device to disconnect from the network and disabling multicast functionality) directly. power_save and power_restore hooks are added meaning that card drivers can take steps to turn the device off when the interface is down. The MAC address can now only be changed when all interfaces are down; the new address will be programmed when an interface gets brought up. This matches mac80211 behaviour. Also, some small cleanups/simplifications were made in the surrounding device handling logic. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
