new if_sk locking patch...

Ok, I just happen to pick up a Belkin F5D5005 Gige card.  (I couldn't
resist at $25.)  They were nice enough to include Linux drivers on the
CD (yeh!) which made it much easier for me to find out what driver it
was compatible with.  It didn't take much time to get the card working.

Of course, once I had the card working I was getting soooo many LOR's
that my serial console was overloaded.  I took Doug White's patch and
modified it a little.  I left in the recursion since I wanted to get
it working first.

So, here it is attached, and availabe at:
http://people.freebsd.org/~jmg/if_sk.diff

I don't get any LOR's w/ this patch and debug.mpsafenet=1.  I didn't
try using it as a module though.  (Hence I don't know if kldload/kldunload
works.)

Test it out and let me know how it works for you.

Thanks!
