Subject: [RFC/TEST] 2.6.28-rc3 dmfe fixes for bug 9094
This patch is am attempt to "port" phy setup fixes from the tulip driver
to the dmfe driver. Can someone with dmfe HW please test this?
Patch was originally written for 2.6.23 but applies correctly to
2.6.28-rc3 with "offset 10 lines" for all of the hunks.
I'm trying to wrap up work on bug 9094:
http://bugzilla.kernel.org/show_bug.cgi?id=9094
thanks,
grant
