Subject: [PATCH net 5/8] netlink: specs: rt-link: add an attr layer around alt-ifname

alt-ifname attr is directly placed in requests (as an alternative
to ifname) but in responses its wrapped up in IFLA_PROP_LIST
and only there is may be multi-attr. See rtnl_fill_prop_list().

Fixes: b2f63d904e72 ("doc/netlink: Add spec for rt link messages")
