Subject: xenserver: Implement missing interface-reconfigure settings.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=47a3c536c345925b6d3837643b0e8a24b752fad3;p=openvswitch

xenserver: Implement missing interface-reconfigure settings.

These settings are supported by the bridge, and they were supported
earlier by the vswitch, but support regressed when OVSDB was initially
introduced because at first ovs-vsctl did not support these settings.
This commit restores support.

Related to bug #2430, #2442.
