[CentOS-devel] centos8 openvswitch-dpdk RPM

Just to follow up,

I have successfully deployed ovs+dpdk on centOS-8 on ussuri using the
following repo. (openvswitch2.13)

dnf install -y centos-release-nfv-openvswitch

Just curious why RPM package name is openvswitch2.13 instead of
openvswitch-2-13 (Let me guess because of centOS RDO provides that
same naming style right?)

You can download those wrappers from https://cbs.centos.org/koji/buildinfo?buildID=31051 (you need all RPMs in noarch list), create a local repository with them and add it to all nodes in the cluster.
