This patch fixes a regression which was introduced by:
"carl9170: split up carl9170_handle_mpdu"
Previously, the ieee80211_rx_status was kept on the
stack of carl9170_handle_mpdu. Now it's passed into
the function as a pointer parameter. Hence, the old
memcpy call needs to be fixed.

As described in the documentation of bcma_wflush16 in drivers/net
/wireless/brcm80211/brcmsmac/types.h some PCIe controllers of Broadcom
SoCs are broken. The PCIe controller on these SoCs are mostly used to
connect some additional wifi device to the SoC and some of these wifi
devices are supported by brcmsmac.
For my BCM43224 connected to the broken PCIe controller of the BCM4718 I
need an extra read after write in brcms_b_write_objmem() to prevent a
Data bus error. This fixes the problem reading tsf_random later.

Commit "ath9k: Fix the 'xmit' debugfs file" changed the
the array size of ath_stats.txstats to IEEE80211_NUM_ACS,
which is wrong because the HW queue number is used to
update the statistics. Revert back to using ATH9K_NUM_TX_QUEUES.

Recent versions of udev cause synchronous firmware loading from the
probe routine to fail because the request to user space times out.
The original fix for b43legacy (commit a3ea2c7) moved the firmware
load from the probe routine to a work queue, but it still used synchronous
firmware loading. This method is OK when b43legacy is built as a module;
however, it fails when the driver is compiled into the kernel.
This version changes the code to load the initial firmware file
using request_firmware_nowait(). A completion event is used to
hold the work queue until that file is available. The remaining
firmware files are read synchronously.

This adds support for bcma wifi core revision 17 which is found on
BCM4716/4717/4718 SoCs. The firmware version 610.812 for brcmsmac found
in linux-firmware does not support these cores, but a firmware
generated with b43-fwcutter from the proprietary broadcom wireless
driver works with these chips. This wifi core contains a revision 5
N-PHY and a revision 7 radio of type 0x2056.

This reverts commit f74b9d365ddd33a375802b064f96a5d0e99af7c0.
Turns out reverting commit a240dc7b3c7463bd60cf0a9b2a90f52f78aae0fd
"ath9k_hw: Updated AR9003 tx gain table for 5GHz" was not enough to
bring the tx power back to normal levels on devices like the
Buffalo WZR-HP-G450H, this one needs to be reverted as well.
This revert improves tx power by ~10 db on that device

Inspection of the pci_read_config_dword() function showed it can
