Subject: [PATCH net-next v2 0/6] tsnep: XDP support

Implement XDP support for tsnep driver. I tried to follow existing
drivers like igb/igc as far as possible. Some prework was already done
in previous patch series, so in this series only actual XDP stuff is
included.

Thanks for the NetDev 0x14 slides "Add XDP support on a NIC driver".

v2:
- move tsnep_xdp_xmit_back() to commit where it is used (Paolo Abeni)
- remove inline from tsnep_rx_offset() (Paolo Abeni)
- remove inline from tsnep_rx_offset_xdp() (Paolo Abeni)
- simplify tsnep_xdp_run_prog() call by moving xdp_status update to it (Paolo Abeni)

Gerhard Engleder (6):
  tsnep: Add adapter down state
  tsnep: Add XDP TX support
  tsnep: Support XDP BPF program setup
  tsnep: Prepare RX buffer for XDP support
  tsnep: Add RX queue info for XDP support
  tsnep: Add XDP RX support
