This patch fixes a bug in Rate Scaling. When moving from SISO to MIMO we
need to choose the lowest higher rate, instead of choosing the highest in MIMO.
No doing this can lead to a high packet loss in the highest rate in MIMO,
leading not to move MIMO although lower in MIMO could give a better TPT.

If certain commands were in-flight when the card was pulled or the

work queue was in turn blocked on the current command being canceled,
which didn't happen. Fix that.

Remove driver specific RFKILL configuration options
and make the rt2x00lib version depend on CONFIG_RFKILL

be enabled when RFKILL was enabled.
This also fixes some bugs where RFKILL wasn't initialized

This patch makes usage of the results from disconnected antenna alg to
know how many antennas are connected.
It also synchronizes between the chain noise alg and the W/A that
disables power management during association. All the antennas must be
enables during the chain noise algorithm. Hence, power management is
restored only after the completion of the algorithm.
In the future, we will need to update the AP that we don't support MIMO
if there is only one antenna connected. We also need to update the rate
scaling algorithm.

Note: To inject management frames with encryption, HW crypto support
must be disabled using the "swcrypto=1" modparam (or "swcrypto50=1"

adapters integrated into the NVidia MCP55 chipsets fail to work in kexeced

during ->shutdown(), it cannot be brought back into D0 after kexec (ref.
http://marc.info/?l=linux-kernel&m=121900062814967&w=4). Therefore, only
