Subject: [PATCH bpf-next 0/2] net: xdp: refactor the XDP_QUERY_PROG and XDP_QUERY_PROG_HW code

Here's another attempt (the first, horribly broken one, here [1]) to
move the XDP_QUERY_PROG{,_HW} code out from the drivers to generic
netdev code.

The first patch in the series move the XDP query functionality, and
the second remove XDP_QUERY_PROG{,_HW} from all drivers.

Please refer to the individual commit messages for more details.

Shout out to all XDP driver hackers to check that the second patch
doesn't break anything (especially Jakub). I've only been able to test
on the Intel NICs.


Thanks,
Björn
