disregard that tree, its there just for historical purposes now.

I've noted elsewhere that what we need to do is to backport these
patches from linux-next:

22bedad3ce112d5ca1eaf043d4990fa2ed698c87 net: convert multicast list
to list_head
2f787b0b76bf5de2eaa3ca3a29d89123ae03c856 mac80211: Ensure initializing
private mc_list in prepare_multicast()

You can get compat-wireless working by reverting these patches (to
what does apply). Its what I would do to backpor t it. We cannot add
the new stuff as the new stuff relies on new changes to internal data
structures, so the way to properly backport this is to ifdef around
the new code and add the reverted code for older kernels.

I haven't had time to do this yet as it involves changes not only on
mac80211 but also on a few other drivers like libertas, etc. It should
be fairly easy to do just haven't had time yet.
