2013-01-11mwifiex: update config_bands during infra associationAmitkumar Karwar2-14/+15
Currently "adapter->config_bands" is updated during infra association only if channel is provided by user in "iw connect" command. config_bands is used while preparing association request to calculate supported rates by intersecting our rates with the rates advertised by AP. There is corner case in which we include zero rates in supported rates TLV based on previous IBSS network history, which leads to association failure. This patch fixes the problem by correctly updating config_bands.

2013-01-09ath9k: add spectral scan featureSimon Wunderlich10-1/+653
Adds the spectral scan feature for ath9k. AR92xx and AR93xx chips are supported for now. The spectral scan is triggered by configuring a mode through a debugfs control file. Samples can be gathered via another relay debugfs file. Essentially, to try it out: echo chanscan > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl iw dev wlan0 scan cat /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan0 > samples echo disable > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl This feature is still experimental. The special "chanscan" mode is used to perform spectral scan while mac80211 is scanning for channels. To allow this, sw_scan_start/complete() ops have been added. The patch contains code snippets and information from Zefir Kurtisi and information provided by Adrian Chadd and Felix Fietkau.

2013-01-07mwl8k: Handle watchdog event with highest prioriryYogesh Ashok Powar1-0/+19
Currently, command path waits till all the tx host queues are empty. Whenever watchdog event is raised, firmware expects driver to destroy ampdu queues immediately. This requires corresponding commands i.e. mwl8k_cmd_get_watchdog_bitmap and mwl8k_destroy_ba to be sent without waiting for the tx queues to be completely empty. Use "watchdog_event_pending" to ensure the above mentioned two commands are sent down immediately.
