p54: connect to 11w protected networks
Previously, it was not possible to connect to
networks which requires 11w to be supported by
the stations.
Note:
As all current (and old) firmwares corrupt
incoming, protected management frames, the
decryption offloading needs to be disabled.
This will be done automatically if needed.
