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 drivers/net/ethernet/broadcom/bnxt/bnxt_xdp.c | 1 - .../net/ethernet/cavium/thunder/nicvf_main.c | 1 - drivers/net/ethernet/intel/i40e/i40e_main.c | 1 - drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 1 - .../net/ethernet/intel/ixgbevf/ixgbevf_main.c | 1 - .../net/ethernet/mellanox/mlx4/en_netdev.c | 1 - .../net/ethernet/mellanox/mlx5/core/en_main.c | 1 - drivers/net/ethernet/netronome/nfp/bpf/main.c | 11 +-- drivers/net/ethernet/netronome/nfp/nfp_net.h | 10 ++- .../ethernet/netronome/nfp/nfp_net_common.c | 58 ++++++--------- .../net/ethernet/qlogic/qede/qede_filter.c | 1 - drivers/net/netdevsim/bpf.c | 41 ++++------- drivers/net/netdevsim/netdev.c | 3 +- drivers/net/netdevsim/netdevsim.h | 6 +- drivers/net/tun.c | 1 - drivers/net/virtio_net.c | 1 - include/linux/netdevice.h | 12 ++-- include/net/xdp.h | 13 ++++ include/uapi/linux/if_link.h | 4 ++ net/core/dev.c | 48 +++++++------ net/core/rtnetlink.c | 71 ++++++++++++++----- net/core/xdp.c | 34 +++++++++ tools/testing/selftests/bpf/test_offload.py | 71 ++++++++++++++++--- 23 files changed, 246 insertions(+), 146 deletions(-) -- 2.17.1
