Subject: qemu: interface: check and use ovs command to set qos of ovs managed port
X-Git-Tag: v7.6.0-rc1~233
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2f922b2c464cc2873fc17280ef459848ee945a6f;p=thirdparty%2Flibvirt.git

qemu: interface: check and use ovs command to set qos of ovs managed port

When qos is set or delete, we have to check if the port is an ovs managed
port. If true, call the virNetDevOpenvswitchInterfaceSetQos function when qos
is set, and call the virNetDevOpenvswitchInterfaceClearQos function when
the interface is to be destroyed.
