Open vSwitch (OVS)

Here are the steps to get Open vSwitch loaded ~~up.~~up from source (don't let that scare you, we are still going to use RPMs).
There are other directions out there. ~~This~~Now, isthis will be one of them.

NOTE: I have included some cleanup actions and some manual dependency installs. Just use what you need if not all of it.

# REBOOTED
reboot

NOTE: If you want your RPM's to be compiled with DPDK, you will need to also go grab the ~~database~~DPDK isversion ~~good~~22.x source and build that as well. Rocky 8.8 only has the 21.x packages available. I opted to gonot ~~ovs-vsctl~~compile ~~show~~it

in.
