(RHSA-2021:0931) Important: openvswitch2.11 and ovn2.11 security update

Open vSwitch provides standard network bridging functions and support for
the OpenFlow protocol for remote per-flow control of traffic.

OVN, the Open Virtual Network, is a system to support virtual network
abstraction. OVN complements the existing capabilities of OVS to add native support for virtual network abstractions, such as virtual L2 and L3 overlays and security groups.
