2.6.22 merge plan (removing ioctls)

[Dan Williams]

Libertas is already in 2.6.22, but is going to get removed if we don't
clean up the ioctl situation.  Since we have perhaps a day or so, the
default case will be to simply remove the ioctl and add it back later,
or move its functionality to somewhere else.

The problem is that (a) the existing ioctls look pretty badly planned,
(b) many of them can be folded into WEXT calls, and (c) these are _ABI_
and if they get upstream must be preserved for a long time.

Mesh ioctls will be preserved by default.  All others are subject to
yanking (again, for now) unless somebody gives some really, really good
reasons why they should stay, and why OLPC needs them in the next few
weeks.  Again, they can get added back later, or merged in somewhere
else, and this is only for the 2.6.22 merge.

Javier; do we use the 'nullpktinterval' in a meaningful way right now?
