Subject: selftests: forwarding: devlink_lib: Support port-less topologies
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5b3a53c9c843b84955d5a3abda358518a3031630;p=linux.git

selftests: forwarding: devlink_lib: Support port-less topologies

Some selftests may not need any actual ports. Technically those are not
forwarding selftests, but devlink_lib can still be handy. Fall back on
NETIF_NO_CABLE in those cases.
