More Details:
I've set up a i386 box with the following exports:
/usr/src /usr/pkgsrc -maproot=root

On my VAX4000/200, with 1.5.1_ALPHA kernel, and 1.5 userland, I can
mount_nfs the /usr/src fine, but when I try to mount_nfs the /usr/pkgsrc, I

ze0: discarding oversized frame

At this point, the vax is useless, unless the mount command was started in
the background. Either way, the process becomes undead - kill -KILL won't
get rid of it. I'll get about a dozen of those messages, with a few seconds
or more separating them.

I've traced this error to src/net/ether_subr.c. - one of the first checks on
an incoming frame is size.

Here's the really annoying part - I tried the same thing on my VAXStation
4000/60, same 1.5.1_ALPHA kernel, same 1.5 userland (well, both have custom
kernels, but from the same source) - and I DON'T GET THE ERROR. It works

Should I send_pr this?
