Because this is such a common usage, perhaps it would be justified to
add dedicated flags to ifconfig like "10base5", "10base2", and "10baseT"?
I know, adding driver-specific flags to ifconfig means a potential explosion
of oddball little flags, but until more than four people total are using
anything other than Ethernet, SLIP, or PPP, that seems like less of a problem.
Of course, this assumes that all ethernet drivers which implement these three
media types interpret link0 and link1 exactly the same.
