Yes, looking at the source to ifconfig (or using strace on ifconfig as
Deepak did) is often the quickest way to find something like this out.

Actually, before I looked at the ifconfig sources, I poked around
/proc for a while thinking the information would be there.  If
it's there, I didn't see it.  I think it'd be handy to have (e.g.) a
/proc/net/devs/eth0 which would provide you with this information.

The strange thing is that there is a /proc/net/dev which lists the
interfaces and certain statistics.
