There was some confusion concerning the units of the beacon interval.
The driver assumed that it was in msec where it was in TU - so fix that.
Skip over dtim was capped by 300TU where it should be by 306TU.
It should also be subjected to several conditions:
Not a DFS channel, dtim period < 10, and the multicast wake-lock
is off.  Concerning multicast lock - there is an implementation gap
in the supplicant, so just leave a TODO.

Fix this by storing the command only when it was also sent.

Reading the temperature directly from the hardware, without the help
of the firmware, is a complex process and is not entirely the same for
different hardware.  Also, some NICs don't easily allow access to the
sensors when the firmware is not running, which would add even more
complexity to the code.

To reduce the code complexity and to avoid code duplication between
the firmware and the driver, boot the firmware briefly to read the
current temperature while in CT kill mode.

Avoid that by only updating the quota command when there are any

Using the LQ table which is initially set according to
the rssi could lead to EAPOLs being sent in high legacy
rates like 54mbps.
It's better to avoid sending EAPOLs in high rates as it reduces
the chances of a successful 4-Way handshake.
Avoid this and treat them like other mgmt frames which would
initially get sent at the basic rate.
