Bug Description
The Linux bridge (qbr) created by the OVS hybrid vif driver sends usefulness IGMP queries.
By default, Linux bridge activates IGMP snooping onto a switch.
In the case of the Linux bridge was created by the OVS hybrid vif driver, is usefulness.
Because this bridge is only here to be able to apply security groups through netfilter (OVS bridge doesn't use netfilter hooks) and so it contains only 2 interfaces: the VM tap and a side of the veth patch port.
IGMP snooping on a switch of 2 ports is unnecessarily.
Furthermore, the Linux bridge could (I didn't find why and when) send some IGMP queries when the IGMP snooping is activated.
This IGMP queries could unnecessarily pollute the network and the network equipemnts log.

Disable IGMP snooping on hybrid Linux bridge
By default, Linux bridge activates the IGMP snooping on his switch.
It is unnecessarily on Linux bridge created by OVS/VIF hybrid vif
drivers because that switch is limited two ports.
That patch also refactoring OVS and IVS plug and unplug unit tests of the
hybrid drivers.
