From: Colin Ian King <colin.k...@canonical.com>
The mask of 0xff and right shift of 8 bits on ret always results in
a value of 0 for TxPowerLevelCCK. I believe this should be a mask of
0xff00, however I do not have the hardware at hand to test this out,
so there is a distinct possibility I may be wrong on this.
