with the `#ifdef notyet' case immediately above.

Garrett,
Here are some patches for the rate limiting code. It should be faster,
and in particular it doesn't leak malloc'd memory any more when rate_limit'ing
a phyint.
It now uses an mbuf chain at each vif, instead of the static queue array.
This means that the MAXQSIZE is now variable per vif (although there is no
interface to change it other than a debugger); this is an area for more
experimentation.

the code up to the minimum standards for inclusion in FreeBSD.

inconsistenly so now it gets done when it is initialized.

the lookup fails. Updated callers to deal with this. Call in_pcblookuphash
instead of in_pcblookup() in in_pcbconnect; this improves performance of
UDP output by about 17% in the standard case.
