will merge the existing patches, or provide feedback as to what it would take to
get them merged. If upstream doesn't see a point in these patches, then I really
don't see much value in continuing to further them. Once hardware comes out, the
value proposition is certainly less.

Having said that, once I get the port/region patches merged for the Linux
driver, I do intend to go back and try to implement a basic switch so that we
can test those flows.

I admit, I'm curious why you're interested in switches.
