Hi,

The patches gives me ifHighSpeed = 1000 on bge interfaces, also where
the interface is forced to 100baseTX. In any case I get ifHCOutOctets
and ifHCInOctets, which was what I was originally looking for. Making
bsnmpd report actual speed seems sensible, yes.

I should make a list of "what bsnmpd needs" to be more usable, in case
Harti is interested. ;-P

Mvh,
