2014-06-05at76c50x: fix scan does not work with latest mac80211Andrea Merello
since commit 3afc2167f60a327a2c1e1e2600ef209a3c2b75b7 scan in not working anymore, due to mac80211 requires rx frequency status information. This patch makes the driver report this information. While NOT scanning this is straightforward. While scanning the firmware performs RF sweep and we cannot track the actual tuning frequency, so this is guessed by parsing beacons and probe responses. This should be enough for ensuring functionality.

The .init() callback was the first function called by the common bus function brcmf_bus_start(). Given that it is not really necessary and the bus layer can call it before calling the brcmf_bus_start() function.

2014-05-29brcmfmac: make chandef_to_chanspec() function staticArend van Spriel
The function chandef_to_chanspec() was added by brcmfmac: determine chanspec from struct cfg80211_chan_def info The struct cfg80211_chan_def contains additional info to derive the bandwidth and side-band information of the chanspec. This patch adds chandef_to_chanspec() function used in IBSS join and starting AP operation. However, it introduced a sparse warning because the function is only called from within the source file wl_cfg80211.c.

2014-05-29brcmfmac: reduce log level for invalid scheduled scan requestArend van Spriel
When a regular scan does not return any networks user-space does request a scheduled scan without any matchset or ssid. This can not be handled by the firmware so we return -EINVAL. However, as this request is done let us not add an error message to the log.

2014-05-29at76c50x-usb: Make WEP encryption working.Andrea Merello
Currently the driver uses HW encryption. Whenever mac80211 calls the set_key() callback the driver restarts the whole HW configuration procedure, in order to set (also) the new WEP key. However, by doing this, it causes the card to loose association information, and the HW becomes unable to communicate with the BSS. This patch adds support for sending another HW command, that sets only the wep key, instead of resetting all. Mac80211 key-set requests are thus handled via this new command.

2014-05-29at76c50x-usb: Don't perform DMA from stack memoryAndrea Merello
Loading the driver with DMA debugging enabled makes the kernel to complain about the ehci driver trying to perform DMA from memory from the stack. [ 9848.229514] WARNING: CPU: 1 PID: 627 at lib/dma-debug.c:1153 check_for_stack+0xa4/0xf0() [ 9848.237678] ehci-pci 0000:00:04.1: DMA-API: device driver maps memory fromstack [addr=ffff88006c80da01] This is due to at76c50x-usb driver passing buffers allocated on the stack to the USB layer, that attempts DMA. This occurs is several places. This patch fixes the problem by allocating those buffers via kmalloc. Since this adds some kfree() before leaving a couple of functions, I caught the occasion to clean-up the exit path on error.

2014-05-29ath9k: avoid passing buffers to the hardware during flushFelix Fietkau
The commit "ath9k: fix possible hang on flush" changed the receive code to always link rx descriptors of processed frames, even when flushing. In some cases, this leads to flushed rx buffers being passed to the hardware while rx is already stopped. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
