2013-01-07brcmfmac: assure USB dongle firmware is reset upon module unloadArend van Spriel
Upon unloading the brcmfmac module the USB firmware should be reset as the device remains powered. The reset assures a known device state when a new brcmfmac driver load is being done.

Both the rtt2x00usb_eeprom_read and the ioremap functions are allowed to fail, however their return values are not checked in the read_eeprom functions in the rt2800{pci,usb} drivers.

Some 3-column initval arrays have wrong comments. The column of these arrays is indexed by the 'freqIndex' variable in 'ar5008_hw_process_ini' which only depends on the actual band. The 'initvals' tool from 'qca-swiss-army-knife' prints the correct comment lines for these arrays, since commit 'atheros-initvals: fix comments for non-fastclock 3-column tables' however the comments were not refreshed in ath9k.

2013-01-03mac80211: split TX aggregation stop actionJohannes Berg
When TX aggregation is stopped, there are a few different cases: - connection with the peer was dropped - session stop was requested locally - session stop was requested by the peer - connection was dropped while a session is stopping The behaviour in these cases should be different, if the connection is dropped then the driver should drop all frames, otherwise the frames may continue to be transmitted, aggregated in the case of a locally requested session stop or unaggregated in the case of the peer requesting session stop. Split these different cases so that the driver can act accordingly; however, treat local and remote stop the same way and ask the driver to not send frames as aggregated packets any more. In the case of connection drop, the stop callback the driver is otherwise supposed to call is no longer required. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-01-03nl80211/mac80211: support full station state in AP modeJohannes Berg
Today, stations are added already associated. That is inefficient if, for example, the driver has no room for stations any more because then the station will go through the entire auth/assoc handshake, only to be kicked out afterwards. To address this a bit better, at least with drivers using the new station state callback, allow hostapd to add stations in unauthenticated mode, just after receiving the AUTH frame, before even replying. Thus if there's no more space at that point, it can send a negative auth frame back. It still needs to handle later state transition errors though, of course.
