Because nobody would ever want to send an IP packet bigger than
32K, right?  I posted some patches for this earlier in the year,
and I promise I'll do a send-pr on it within the next week, :-)
as soon as I get the actual 1.2 release running.

I'll also try to spend a little time to ensure that the Win95
ping bug (bogusly large pings crashing various systems) doesn't
bite us...
