2014-04-22b43: N-PHY: fix selection of init & calib valuesRafał Miłecki
Logic in specs and our code was wrong. Init and calibration values for newer cards depend on radio revision, not PHY revision. To make code clearer, change tables names to include "radio" or "phy".

For PCIe, aggregate more AMSDU packets till PCIe TXBD is full.

2014-04-22wil6210: relaxed check for BACK start sequenceVladimir Kondratiev
Sometimes, due to the race between Rx path and WMI_BA_STATUS_EVENTID WMI event, few frames may be passed to the stack before reorder buffer allocated. Then, after BACK establishment, it start getting frames with sequence number ahead of SSN, and it get interpreted as missing frames. Then, BACK mechanism will wait for missing frames; data traffic will be stopped. In case of interface configured for DHCP, this data delay causes DHCP failure. Relax checking for sequence number; use sequence of 1-st frame handled by the buffer as SSN for this buffer. This is work-around, real fix should be done when proper BACK mechanism implemented.

2014-04-22rtl8180: be paranoid in stopping unused queues.Andrea Merello
HW should never attempt to perform DMA for unused queues. For rtl8187se this is ensured by setting a dedicated register at init time, before enabling TX. In rtl8180/5 the register is only written at the first TX (because in rtl8180/5 it serves also to kick DMA for used queues). This should be enough, but it's worth to add a register write at init time, before enabling TX. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-04-22rtl8180: add parentheses to REG_ADDR macrosAndrea Merello

2014-04-22rtl8180: fix enabled interrupt mask for rtl8187seAndrea Merello
When preparing the bitfield to write to HW register, the high-priority queue error interrupt bit is set two times, and the beacon queue TX-OK interrupt is not enabled. Currently this have no functional impact because the high-priority queue is not used at all, and the beacon queue is not used yet. This patch removes high-priority queue bits and it adds the beacon queue missing bit. It removes also the management queue bits because it is not used. This was found by static code analyzer.

2014-04-22ath9k: add a recv budgetTim Harvey
Implement a recv budget so that in cases of high traffic we still allow other taskets to get processed. Without this, we can encounter a host of issues during high wireless traffic reception depending on system load including rcu stall's detected (ARM), soft lockups, failure to service critical tasks such as watchdog resets, and triggering of the tx stuck tasklet. The same thing was proposed previously by Ben: http://www.spinics.net/lists/linux-wireless/msg112891.html The only difference here is that I make sure only processed packets are counted in the budget by checking at the end of the rx loop.
