This updates ath5k to calibrate the noise floor similar to the way it is done in the madwifi hal and ath9k. Of note: - we start NF measurement at the same time as AGC calibration, but do not actually read the value until the periodic (long) calibration - we keep a history of the last few values read and write the median back to the hardware for CCA - we do not complain if NF calibration isn't complete, instead we keep the last read value.

During rename of the driver from wl12xx to wl1251 the spi device name was accidentally left as wl12xx. Rename it to wl1251 which is the proper name of the driver. Signed-off-by:

It might be the case that __cfg80211_disconnected() has already cleaned up wdev->current_bss() for us. The old code didn't catch that situation and didn't warn needlessly. Signed-off-by:

We cannot be in PS mode when running PLT tests, so we need to make sure we're in active mode. Also, we need to clear up the rx_counter when we stop PLT, otherwise it could cause problems when entering PLT again. Signed-off-by:

Several memory allocation related failure cases were not properly handled by the driver - the result was that in low memory conditions booting of a corrupted FW could be attempted - and user space would not get proper failure code. Signed-off-by:

Add support for IPv4 ARP filtering in the driver. This will dramatically reduce the number of unnecessary interrupts by the device in conqested networks. This patch is based on a similar patch to wl1251 by Janne Ylälehto. Cc: Janne Ylälehto <janne.ylalehto@nokia.com> Signed-off-by:

Fixed checking of status of the received packet. On wl1251 status is in the flags field of the descriptor, on wl1271 there is a separate status field. Signed-off-by:

This switches the iwlwifi driver to use paged skb from linear skb for Rx buffer. So that it relieves some Rx buffer allocation pressure for the memory subsystem. Currently iwlwifi (4K for 3945) requests 8K bytes for Rx buffer. Due to the trailing skb_shared_info in the skb->data, alloc_skb() will do the next order allocation, which is 16K bytes. This is suboptimal and more likely to fail when the system is under memory usage pressure. Switching to paged Rx skb lets us allocate the RXB directly by alloc_pages(), so that only order 1 allocation is required. It also adjusts the area spin_lock (with IRQ disabled) protected in the tasklet because tasklet guarentees to run only on one CPU and the new unprotected code can be preempted by the IRQ handler. This saves us from spawning another workqueue to make skb_linearize/__pskb_pull_tail happy (which cannot be called in hard irq context). Finally, mac80211 doesn't support paged Rx yet. So we linearize the skb for all the management frames and software decryption or defragmentation required data frames before handed to mac80211. For all the other frames, we __pskb_pull_tail 64 bytes in the linear area of the skb for mac80211 to handle them properly. Signed-off-by:

We were using the join command to change some settings when the stack asked us to do it. In many cases they were not needed (and could cause potential problems), so they were removed. In other cases there are ACX commands that can be used instead of using join to reconfigure. Signed-off-by:

We shouldn't use a join command to change the filter settings while associated. The right way to do it is to use ACX_RX_CFG. Signed-off-by:
