There is documentation for the net80211 subsystem in section 9 of the
man pages.

This diagnostic indicates the driver lacks support to push multicast
filtering to the h/w.  This can be fixed either by fixing the driver (if
the h/w is capable) or by adding s/w multicast filtering support in the
kernel to handle it instead.  When the latter is done then the net80211
code can be changed to enable that functionality when the driver lacks
support for pushing the multicast list into the h/w.

This issue has been discussed numerous times but noone has stepped up to
fix the ALLMULTI support.
