Ok, I've just checked out this set of patches (finally!). Sorry
for the delay. It turns out that NetBSD 1.2 was not vulnurable to
the `Windows 95 65510 size ping bug.' (A `ping -l 65510 host' would
panic a Linux machine.)

The new patches seem to work fine. I can't get NetBSD's ping program
to generate packets larger than the physical network's MTU (I don't
know if this is a problem with ping or the kernel), but Windows 95
machines do this quite happily. For packets of reasonable size
(about 65000 bytes and under) NetBSD with these patches returns
the large pings. Note, however, that Windows 95 has a tendency to
drop these large returned packets, and will claim that it's not
getting responses when indeed it is. (I verified this with tcpdump
on a third machine.)
