2011-08-22bcma: implement BCM4331 workaround for external PA linesRafał Miłecki3-1/+43
We need to disable ext. PA lines for reading SPROM. It's disabled by default, but this patch allows using bcma after loading wl, which leaves workaround enabled.

2011-08-22mac80211: Tear down BA session on BAR tx failureHelmut Schaa1-0/+18
As described at [1] some STAs (i.e. Intel 5100 Windows) can end up correctly BlockAcking incoming frames without delivering them to user space if a AMPDU subframe got lost and we don't flush the receipients reorder buffer with a BlockAckReq. This in turn results in stuck connections. According to 802.11n-2009 it is not necessary to send a BAR to flush the recepients RX reorder buffer but we still do that to be polite. However, assume the following frame exchange: AP -> STA, AMPDU (failed) AP -> STA, BAR (failed) The client in question then ends up in the same situation and won't deliver frames to userspace anymore since we weren't able to flush its reorder buffer. This is not a hypothetical situation but I was able to observe this exact behavior during a stress test between a rt2800pci AP and a Intel 5100 Windows client. In order to work around this issue just tear down the BA session as soon as a BAR failed to be TX'ed.

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: remove eeprom txgain override for minor version < 19Marek Lindner1-4/+1
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.

When a PREQ or PREP is received from an intermediate node, it contains useful information for path selection but it doesn't include the originator's sequence number. Therefore, when updating the mesh path to that intermediate node, we should not set the MESH_PATH_SN_VALID flag.

2011-08-09rt2x00: Fix PCI interrupt processing race on SMP systemsHelmut Schaa5-95/+64
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.

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.
