Make sure we don't store the table offsets for min and cur power levels,
store the 0.25dB values instead. This way we don't clamp the tx power level
to max (because now cur_pwr holds the 0.25dB value, not the table offset) after
re-using cur_pwr on reset.

For the upcoming tpc changes, the driver needs
to provide sensible max output values for each
supported channel.

And while the eeprom always had a output_limit
table, which defines the upper limit for each
frequency and modulation, it was never really
useful for anything... until now.

Note: For anyone wondering about what your card
is calibrated for: check "iw list".

Earlier scan command was postponed by 20msec multiple times to give
preference to Tx traffic until we find empty wmm queue.

There is a corner case in which wmm queue becomes empty immediately
after processing the packet(before 20msec) and there may be next
packet coming after some time. In this case we should not resume scan
operation.

We will use new flag to check Tx traffic and resume scan operation
only if there is no traffic for 200msec.

Drivers that load firmware from their probe routine have problems with the
latest versions of udev as they get timeouts while waiting for user
space to start. The problem is fixed by using request_firmware_nowait()
and delaying the start of mac80211 until the firmware is loaded.

To prevent the possibility of the driver being unloaded while the firmware
loading callback is still active, a completion queue entry is used.
