This is the test_tools_memleak issue I mentioned.
https://github.com/iovisor/bcc/issues/1685

I would be great if somebody who knows python (esp. python3) better
can help take a look.

Unfortunately, I missed the call. Appreciate that AF_XDP was took into
discussion! Thanks for the review!

Jesper:
- Testing AF_XDP patches currently
- no driver changes needed with xdp_redirect
- driver changes still needed for zerocopy
- intel: 12mpps, mlnx: 9mpps drop

Again, thanks a lot for spending time on the AF_XDP patchset!


Cheers,
Björn
