3a643d244f rt2x00: Fix in_atomic() usage
rt73usb and rt2500usb used in_atomic to determine
if a configuration step should be rescheduled or not.
Since in_atomic() is not a valid method to determine
if sleeping is allowed we should fix the way this is handled
by adding a new flag to rt2x00.

In addition mark LED class support for the drivers broken
since that also uses the broken in_atomic() method but
so far no solution exists to have LED triggers work only
in scheduled context.

866a050384 rt2x00: Fix rate detection for invalid signals
It has been observed on rt2500pci hardware that some
frames received with signal 0x0C do not have the OFDM
flag set.

Signals can have 2 meanings:
 1) The PLCP value
 2) The bitrate * 10

For rt2500pci (1) is for frames received with a OFDM rate,
and (2) is for frames received with a CCK rate.
But 0x0C is a invalid bitrate value but is a valid PLCP
value for 54Mbs (obvious OFDM rate).
This means that it is possible that the hardware does not
set the OFDM bit correctly under all circumstances.
This results in rt2x00 failing to detect the rate and
mac80211 triggering a WARN_ON() and dropping the frame.

To bypass this, print a warning when such a frame is received,
and reset the rate to the lowest supported rate for the current band.

fab7d4a2b1 mac80211: filter scan results on unusable channels
When you have an AP on channel 13, it will currently often enough
be listed in scan results even when the regulatory domain restricts
to channels 1-11. This is due to channel overlap. To avoid getting
very strange failures, don't show such APs in the scan results. The
failure mode will now go from "I can see the AP but not associate"
to "I can't see the AP although I know it's there" which is easier
to debug.

This problem was first really noticed by Jes Sorensen.

  also don't blindly get the counters when associating. Getting the
  counters then the user asks via WEXT for them is good enought.
* don't set wstats.discard.fragment with log.rxfrag, because the latter is
