* introduces #define's for subscription event bitmask values
* add a function to search for a specific element in an IE

This patch moves all firmware load responsibility into the interface-specific
code and gets rid of the firmware pointer in the generic card structure. It
also removes 3 fairly unecessary callbacks: hw_register_dev, hw_unregister_dev,
and hw_prog_firmware. It also makes the init sequence from interface
probe functions more logical, as there are paired add/remove and start/stop
calls into generic libertas code.
Because the USB driver code uses the same TX URB callback for both firmware
upload (where the generic libertas structure isn't initialized yet) and for
normal operation (where it is), some bits of USB code have to deal with
'priv' being NULL. All USB firmware upload bits have been changed to not
require 'priv' at all, but simply the USB card structure.

To activate monitor mode,
echo mode > /sys/class/net/{ethX,mshX}/device/libertas_rtap
where mode is the hex mask that specifies which frames to sniff (in short, 0x1
for data, 0x2 for all management but beacons, 0x4 for beacons). Any non zero

Introduce libertas_fw_index_to_data_rate and libertas_data_rate_to_fw_index

than a rate array.
The firmware requires the 4 basic rates to have the MSB set, but most
other stuff doesn't, like WEXT and mesh ioctls. Therefore, only set the MSB
on basic rates when pushing rate arrays to firmware instead of doing a ton
of (rate & 0x7f) everywhere.

With this patch, scanning with mshX interface will only return mesh networks. To
differentiate them, a specific mesh IE in beacons/probe responses is used. This
IE has been introduced in firmware release 5.110.14. Note:
Even though there can be at most a single mesh per channel, this scan might
return several networks in the same channel.
If all nodes in a mesh network are associated to an AP, they won't produce
beacons/probe responses, thus the network will not be listed. This will be fixed
in future firmware releases.
Scan on ethX interface is not filtered, so it will list both mesh and non-mesh

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.
It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.
The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.

device will listen to.
The anycast address range is C0:27:C0:27:C0:XX where XX goes from 00 to 1F (or
0 to 31 in dec). The value to write on anycast_mask will specify which
addresses the device listens to. Bits in a 32 bit int are numbered from 0
(least significative bit) to 31. A specific address ending in YY will be
listened to if bit YY in the value is set to one.
Examples:
0x00000000 : do not listen to any anycast address
0xFFFFFFFF : listen to every anycast address from :00 to :1F
