0112c9e9e8 libertas: Improvements on automatic tx power control via SIOCSIWTXPOW.
iwconfig txpower can now be used to set tx power to fixed or auto. If set to
auto the default firmware settings are used.

The command CMD_802_11_PA_CFG is only sent to older firmware, as Dan Williams
noted the command was no longer supported in firmware V9+.

90d7795e15 iwlwifi: fix searching for best rate in new search column
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.

71b35f3abe libertas: clear current command on card removal
If certain commands were in-flight when the card was pulled or the
driver rmmod-ed, cleanup would block on the work queue stopping, but the
work queue was in turn blocked on the current command being canceled,
which didn't happen.  Fix that.

as one can see on the huge jump, it's very plausible that firmware does not report the

04816448d8 iwlwifi: use the results from disconnected antenna algorithm
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.

Handle station IDs of transmitted packets when in monitor mode, and

This makes injection work on iwl4965 and iwl5000. Tested on both cards.

Note: To inject management frames with encryption, HW crypto support
must be disabled using the "swcrypto=1" modparam (or "swcrypto50=1"
for iwl5000). Otherwise most management frames won't be transmitted.

 * no problems anymore with packages > 1399 octets (without lowering the MTU).
 * monitor mode finally works on USB for more than just a few seconds.
