Hi Mark :)

Yeah, i know, as we use the MV64361 in the Pegasos 2 motherboards here at

Yes, and is in drivers/net.

Ok, so the code in question is in addition to the existing driver from the
mips guys and works with it ? I had the impression that it was a separate
driver development or something.

Ok. Do you know if Dale's patches are available separatedly while they are not
yet in mainline, so Nicolas Det can work on them and make sure they also work
on the Pegasos board, which is not an embedded board but from the chrp
lineage. Nicolas already did some mv643xx ethernet driver work last summer,
but apparently had trouble integrating this in the mainline kernel, and it
seems his work has now been redone by Dale or something. Do you know who the
right person to communicate with about this would be ? The MIPS folk didn't
reply to any of our mails about this subject.

I think so. I was just surprised to see this 64x6x work go to arch/ppc instead
to drivers/net. I haven't really looked at the code though. Nicolas could you
comment on this ?
