We had 0x9912 but AR_PHY_SPECTRAL_SCAN is 0x9910. By using the

to move forward with hardware reset on ar9271 on the ath9k_htc

The CAPI interface incorrectly assumed that CAPI messages would always
start at the beginning of the data buffer: fix by treating DATA_B3
messages as the link layer header to their payload data. This fix
changes the way acknowledgement information is propagated through the
hardware specific modules and thereby impacts the ISDN4Linux variant
of the driver, too.
Also some assumptions about methods not being called from interrupt
context turned out to be unwarranted; fix by using dev_kfree_skb_any()
wherever non-interrupt context isn't guaranteed.

In mii monitor mode, bond_check_dev_link() calls the the ioctl
handler of slave devices. It stores the ndo_do_ioctl function
pointer to a static (!) ioctl variable and later uses it to call the
handler with the IOCTL macro.
If another thread executes bond_check_dev_link() at the same time
(even with a different bond, which none of the locks prevent), a
race condition occurs. If the two racing slaves have different
drivers, this may result in one driver's ioctl handler being
called with a pointer to a net_device controlled with a different
driver, resulting in unpredictable breakage.
Unless I am overlooking something, the "static" must be a
copy'n'paste error (?).

Devices with loadable firmware must have their firmware reloaded
after the system resumes from sleep, but the request_firmare()
API is not available at this point in the resume flow because
tasks are not yet running, and the system will hang if it is
called. Work around this issue by only calling request_firmware()
for a device's first firmware load, and cache a copy of the pointer
to the firmware blob for that device, so that we may reload firmware
images even during resume.
