'netdev' word seems redundant here. 'netdev' and 'interface' are basically words that describe the same thing in this context. And the 'interface' should be preferred in the user documentation, as that is the entity users actually interact with via database. > + </p> > + > + <column name="status" key="xdp-mode"> > + XDP mode which was chosen. The "was chosen" here is a bit ambiguous as it may be interpreted as both "chosen by the user" and "chosen by OVS itself". "currently in use" might be a better way to describe the meaning, as it kind of was before. It might also be useful to reference the <ref column="options" key="xdp-mode" /> for the description of the possible values. > + </column> > + > + </group> > </group> > > <group title="Statistics"> _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
