A partner requested the ability to loop back TX onto an RX queue.

Is this just XDP to XDP loopback, or could this be used to loopback to the normal stack?

XDP to XDP loopback. We can already loop back to the stack, sort of, in the sense that you can create a TX socket that is actually RX-inject.

Does Linux support this today?
