BPF at Facebook and beyond

I'm aware of the xdp support, but it's brand new, and certainly nowhere near as mature as the normal mode. It doesn't even work on most NICs yet.

But I agree that once it's more mature, it will be better overall.

From the latest DPDK docs in your link:

"Current implementation only supports single queue, multi-queues feature will be added later.

Note that MTU of AF_XDP PMD is limited due to XDP lacks support for fragmentation."

That's a non-starter for many use cases, since multiple queues is a fundamental feature of DPDK.
