Hi David, hi Jakub, hi Paolo, hi Eric,

The following pull-request contains BPF updates for your *net-next* tree.

We've added 21 non-merge commits during the last 18 day(s) which contain
a total of 21 files changed, 1185 insertions(+), 127 deletions(-).

The main changes are:

1) Put xsk sockets on a struct diet and add various cleanups. Overall, this helps
   to bump performance by 12% for some workloads, from Maciej Fijalkowski.

2) Extend BPF selftests to increase coverage of XDP features in combination
   with BPF cpumap, from Alexis Lothoré (eBPF Foundation).

3) Extend netkit with an option to delegate skb->{mark,priority} scrubbing to
   its BPF program, from Daniel Borkmann.

4) Make the bpf_get_netns_cookie() helper available also to tc(x) BPF programs,
   from Mahe Tardy.

5) Extend BPF selftests covering a BPF program setting socket options per MPTCP
   subflow, from Geliang Tang and Nicolas Rybowski.
