Neither does /proc/net/dev.
So I looked around and _all around_ the kernel, I see semantics like:
colon=strchr(devname,':');
if (colon)
*colon=0;
Which obviously shortens the name from "eth0:x" to just "eth0".
I guess there was some minor internal rearranging on how aliases are
stored (when fib_* was introduced?).
But is this the behavior we want? To not be able to see what (if any)
ethernet aliases exist? Other than manually trying
ifconfig eth0:207
I don't know of any other way of examining them.
I really don't think we want this.... do we?
