Add loopback TX #51

Open mtfriesen opened 2 years ago

mtfriesen commented 2 years ago

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

nibanks commented 2 years ago

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

mtfriesen commented 2 years ago

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?

mtfriesen commented 3 months ago

No, Linux does not support this.
