The kfree_skb() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

This patch supports handling for printout different chipnames between
atusb and rzusb. The rzusb contains an at86rf230 and atusb an at86rf231
transceiver.

This patch removes the hardware auto acknowdledge flag which indicates
that the transceiver supports this handling. This flag is never
evaluated inside mac802154 and all transceivers should support this
handling by default per hardware.

Atusb uses the at86rf231 transceiver so we can use the same calculation
for txpower settings for it.

With this function we can set individual bits in the registers if needed.
With the old SR_VALUE macro we could only set one bit in the register
which was ok for some scenarios but not for all. With this subreg write
function we can now set more bits defined by the mask while not touching
the rest.
We start using it for the current SR_VALUE use case and will use it more
in upcoming patches.

Since firmware version 0.2 we use AACK handling directly in the firmware.
Inform the stack that the hardware supports and uses it.

Together with mainlining the driver we released a first public binary version
of the device firmware. This is version 0.2. With this change we warn users
who run outdated versions of the firmware. While we have not seen problems
with it yet (thus no error, but a warning only) it would be better to run the
released and tested firmware. You can find released versions here:

This patch adds support for the atusb transceiver.
The current driver supports basic functionality only. Possible further
tasks would be to sync functionality with the at86rf230 driver, because
the atusb use internally an at86rf231 transceiver. Some of these
features need a firmware update like AACK and ARET handling.
I did small changes to this driver to work with xmit_async callback and
setting of a random extended perm address.
