Two users of ar9170 devices have now reported their cards
have been programmed with a regulatory domain of 0x8000.
This is not a valid regulatory domain as such these users were
unable to use these devices. Since this doesn't seem to be
a device EEPROM corruption we must treat it specially. It
may have been possible the manufacturer intended to use 0x0
as the regulatory domain and that would ultimately yield
to US but since we cannot get confirmationf or this we
default this special case to one of our world regulatory
domains, specifically 0x64.

Many Nokia handsets support a Phonet interface to the cellular modem
via a vendor-specific USB interface. CDC Phonet follows the
Communications Device Class model, with one control interface, and
and a pair of inactive and active data alternative interface. The later
has two bulk endpoint, one per direction.
This was tested against Nokia E61, Nokia N95, and the existing Phonet
gadget function for the Linux composite USB gadget framework.

A pointer to mac_sonic_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
Various other functions that are called by mac_sonic_probe need to move
to .devinit.text, too.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Adding support for BCM8727 - a dual port SFP+ PHY. That includes verification of
the optic module vendor and part number - the list of approved modules resides
on the nvram and the module is verified by the FW. Since not all users would
like to use this verification feature, it can be disabled. The default behavior
is to issue a warning if the module is not approved, but still allow using it -
but it is also possible to disable the link if the module is not approved.

For AP mode we must tune ANI specially for 2 GHz and
for 5 GHz. We mask in only the flags we want to toggle
on ath9k_hw_ani_control() through the ah->ani_function
bitmask, this will take care of ignoring changes during
ANI reset which we were disabling before.

some time ago in ath9k by 3f53dd64f1,

That only affects TKIP but it's easiest to just disable that and

This changes the power_level file to adhere to the "one value
per file" sysfs rule. The user will know which power level was
requested as it will be the number just written to this file. It
is thus not necessary to create a new sysfs file for this value.
In addition it fixes a problem where powertop's parsing expects
this value to be the first value in this file without any descriptions.

netxen: fix deadlock on dev close
The tx ring accounting fix in commit cb2107be43
("netxen: fix tx ring accounting") introduced intermittent
deadlock when inteface is going down.
This was possibly combined effect of speculative tx pause,
calling netif_tx_lock instead of queue lock and unclean
synchronization with napi which could end up unmasking
interrupt.
