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 can be done by loading the p54common
module with the nohwcrypt=1 parameter.

v2->v3:
- fixed modparam_nohwcrypt typo
(Yes, v2 never compiled :( )
