First adds support for decoding
IFLA_PROP_LISTattributes in nlpacket viaAttributeLinkPropList.Then adds transparent handling to nlcache/ifupdownmain by caching the link reference for the primary ifname as well as for each altname of the respective interface.
nlmanager by extension itself already handles altnames well, as using
IFLA_IFNAMEin netlink requests already considers interface altnames.Finally, go through property on each addon which can take interface name(s) and add the appropriate translation there too.
