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 drivers/net/ethernet/engleder/Makefile | 2 +- drivers/net/ethernet/engleder/tsnep.h | 31 +- drivers/net/ethernet/engleder/tsnep_main.c | 423 +++++++++++++++++++-- drivers/net/ethernet/engleder/tsnep_xdp.c | 27 ++ 4 files changed, 453 insertions(+), 30 deletions(-) create mode 100644 drivers/net/ethernet/engleder/tsnep_xdp.c -- 2.30.2
