These new attributes are provided to allow that to be done easily, i.e.,
the driver will request the firmware to add the extra IEs (WPS/P2P IE)
to the frames that need them. Whenever the IEs change, a _SET_BEACON
command is used to update the IE contents (just like we do with the full
Beacon template). I'm assuming here that the driver (or well, firmware)
is building rest of the IEs both based on internal knowledge of the
channel and security policy (the newly added attributes). This is
similar to how WPS is normally run with many drivers that use private
WEXT ioctls and the new attributes allow them to move to nl80211 more
easily.
