Jouni Malinen 5ce00d09c0 GAS server: Add support for Protected Dual of Public Action frames
When GAS is used with PMF negotiated, Protected Dual of Public Action
frames are expected to be used instead of Public Action frames, i.e.,
the GAS/ANQP frames are expected to be encrypted. Add support for this
different category of Action frames being used for GAS. The payload
after the Category field is identical, so the only change is in using
the Category field based on what was received in the request frames. For
backwards compatibility, do not enforce protected dual to be used on the
AP side, i.e., follow what the station does.
