hi,
just soliciting opinions for removal of NATM (sys/netnatm).
it has been bitrotting away for what looks like years, never
gets compiled (not even by ALL kernels) and given its condition
I doubt it is used by anyone anywhere.
is there a process to be followed for removing it? is there a
reason to keep it around?
No objection means ok to remove? :)
here's the patch to remove netnatm and en(4). let me know if I missed
anything otherwise I'll commit soon.

- * so we must remember to look at this RX VCI/slot later, but we can't
- * put it back on the hardware service list (since that isn't allowed).
- * so we instead save it on the software service list. it would be nice
- * if we could peek at the VCI on top of the hwservice list without removing
- * it, however this leads to a race condition: if we peek at it and
- * decide we are done with it new data could come in before we have a
- * chance to remove it from the hwslist. by the time we get it out of
