If you're only interested in stuff that goes on iron, openvswitch is out - it's
pure software meant to run on hypervisors


Not necessarily true anymore.  Look for SwitchDev, which is incorporated into the Linux kernel , is undergoing 
continuous improvement, and allows the kernel to offload forwarding rules to the hardware.

This allows open source software like Open vSwitch and Free Range Routing to work natively/directly with hardware.
