Could you please write me an example message of add/remove?

altnames are for existing netdevs, yes? existing netdevs have an id and
a name - 2 existing references for identifying the existing netdev for
which an altname will be added. Even using the altname as the main
'handle' for a setlink change, I see no reason why the GETLINK api can
not take an the IFLA_ALT_IFNAME and return the full details of the
device if the altname is unique.

So, what do the new RTM commands give you that you can not do with
RTM_*LINK?

To put this another way, the ALT_NAME is an attribute of an object - a
LINK. It is *not* a separate object which requires its own set of
commands for manipulating.
