from ifSpeed, which has a maximum of about 4Gb/s.  For higher-speed
interfaces, the value is supposed to be in ifHighSpeed

I can imagine it is reporting that.  I guess I had best go write a patch
for that....

But I don't have any 10G interfaces yet - they are on order, but I'm not
expecting to be able to install them before the middle of January.  If I
write a patch, can I ask you to test it?
