Stephen, can you enlighten me as to the "right" way to do interface
name lookups?  While I can still find examples of parsing
/proc/net/dev, or globbing /sys/class/net/*, I expect these aren't the
preferred method anymore.  Your own iproute2 suite uses RTM_GETLINK
netlink calls, though for the seeming simple case of "give me a list of all
interfaces", your path through there is far more capable (and
complex) than I would hope to need.

Please advise.

libnetdevname does not use ifindex at all at present.

Thanks,
Matt
