Subject: [PATCH bpf-next 0/7] xdp: simultaneous driver and HW XDP

Hi!

This set is adding support for loading driver and offload XDP
at the same time.  This enables advanced use cases where some
of the work is offloaded to the NIC and some is done by the host.
Separate netlink attributes are added for each mode of operation.
Driver callbacks for offload are cleaned up a little, including
removal of .prog_attached flag.

Jakub Kicinski (7):
  xdp: add per mode attributes for attached programs
  xdp: don't make drivers report attachment mode
  xdp: factor out common program/flags handling from drivers
  xdp: support simultaneous driver and hw XDP attachment
  netdevsim: add support for simultaneous driver and hw XDP
  selftests/bpf: add test for multiple programs
  nfp: add support for simultaneous driver and hw XDP
