Would be curious about
the numbers. You'd get implicit batching for the forwarding via devmap
as well if you're required to flush it out via different device with
XDP_REDIRECT; otherwise XDP_TX of course. Given we have recently
integrated helpers for XDP to do a FIB and neighbor lookup from the
kernel tables, where it's thus shared and integrated with the rest of
the stack and tooling, it would be awesome to get to the same point
with xfrm as well. Eyal recently did a start on that for xfrm for tc
progs; would be nice to have integration on XDP as well, potentially
it might also result in a bigger plus on the forwarding numbers.

It might make sense to intrgrate XDP with xfrm to
be able to compare numbers etc. But I need a working
XDP setup and some understanding about it first, what
could take some time.

Okay, no prob. If you have any questions feel free to shoot an email.

Thanks,
Daniel
