The Host AP mode in Prism 2/2.5/3 provides for a somewhat special
situation.. It does actually allow sending of (almost) arbitrary packets
and management frames in AP mode. In other words, it should be possible
to create a mac80211-based AP mode driver for Prism 2/2.5/3 to replace
the AP side of the Host AP driver. Whether anyone has enough interest
and time to do that is another question, though.

As far as station functionality is concerned, I would agree that
mac80211 is not a good target for the Host AP driver. If AP side were to
be made available as a mac80211-based driver, it could make more sense
to merge station side from the Host AP driver into orinoco or some kind
of combination of the driver. However, having two different drivers for
same hardware issue would not go anywhere with this.

One of the problems here is that the hardware is question is quite old
and for many practical purposes obsolete, so finding people to work on
this can get difficult. I can certainly come up with much better uses
for my time.. ;-)
