I will ponder the links. I'm not sure if the anchor I sent works as intended on Phabricator, it was supposed to jump near "/* Render scalar extension fields without coupling ifconfig to a driver. */" The idea is to let the driver itself own whatever custom ontology (which could theoretically live in ports or some external package like Intel provides). > >> looI don't think snl_attr_get_parray is appropriate for parser-only > >> attributes. > >> We should use multi-attr instead to avoid too many nested netlink > >> attributes.
