Log message:
While setting up the basic rate bitmask for iwm's firmware, if the AP does
not specify basic rates for either the CCK or OFDM set, add just the most
basic rate to that set (1 Mbit/s in case of CCK, 6 Mbit/s in case of OFDM).
This behaviour matches what code comments seem to imply.
The previous code would add all possible basic rates in such cases.
So if all basic rates were CCK only, the code would add all possible OFDM basic
rates on top. Then the firmware would send some frames at too high rates, e.g.
RTS frames would be sent at 24Mbit/s which is a bit risky on noisy channels.
