This might be a bit long...

We have a couple of Compaq Prosignia 300 computers.  They were purchased
for another project, and were to have run Sunsoft's Interactive UNIX.
But Interactive wouldn't load on them, being unable to find the PCI NCR
disk controller.

So I commandeered them.  I tried to load (the then-current) FreeBSD
2.1.5, but it had the same problem.  No disk.  On the odd chance that
someone had made progress on that front, I downloaded the boot floppy
from the 2.2-beta, which =did= find the disk.  So, I proceeded to do a
network install of 2.2-beta for practice.

I got my 2.1.7-RELEASE CD-ROM in the mail Monday.  I was curious if the
disk controller code had migrated into the stable tree, so I made a boot
floppy from the CD.  I was pleased to see that it succeeded in finding
the disk drive and the CD-ROM drive as well.  So I proceeded to blow
away the 2.2 stuff and reload the whole machine from the CD.  Since this
machine is headed into a production role, I feel better with the
"stable" world for it.

Unfortunately, I had failed to notice that although 2.1.7 now handles
the SCSI controller, it does not handle the PCI ethernet adapter.
Bummer.  No network.

So, here's the question.  How hard would it be to put the PCI ethernet
code from 2.2 into 2.1.7?  Would that be loonie in light of my desire
for stability?

Seems at the minimum, I'd want to move the file

    /usr/src/sys/pci/if_lnc_p.c 

but it looks like I might also want

    /usr/src/sys/i386/isa/if_lnc.c
    /usr/src/sys/i386/isa/if_lnc.h

to be moved over.

Any opinions?
