I also have a MVME167 board, but I'm not sure the ethernet works as I
haven't been able to get any packets out of it.

The kernel you built for me booted right up.  That patch seems good.  Thank you.

I tried the netboot too but it didn't work.  It was a bit odd.  Part
of it was dumped
to the console.  It looks like starting at offset 0x4F7A (20,346) it
dumped to the
console.

Here's the first bit of console output:

Thank you for your help!  I have it booted on your kernel with 6.1.1
userland (via NFS) and it
is working great.  I'll apply the patch to my local sources and cross
build a kernel.
