Subject: openvswitch: Abstract vport name through ovs_vport_name()
X-Git-Tag: firefly_0821_release~176^2~1159^2~330^2~1
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c9db965c524ea27451e60d5ddcd242f6c33a70fd;p=firefly-linux-kernel-4.4.55.git

openvswitch: Abstract vport name through ovs_vport_name()

This allows to get rid of the get_name() vport ops later on.
