Hi: This series brings two optimizations for virtio-net XDP:
- avoid reset during XDP set - turn off offloads on demand Changes from V1: - Various tweaks on commit logs and comments - Use virtnet_napi_enable() when enabling NAPI on XDP set - Copy the small buffer packet only if xdp_headroom is smaller than required Please review. Thanks Jason Wang (5): virtio_ring: allow to store zero as the ctx virtio-net: pack headroom into ctx for mergeable buffers virtio-net: switch to use new ctx API for small buffer virtio-net: do not reset during XDP set virtio-net: switch off offloads on demand if possible on XDP set drivers/net/virtio_net.c | 332 ++++++++++++++++++++++++++----------------- drivers/virtio/virtio_ring.c | 2 +- 2 files changed, 200 insertions(+), 134 deletions(-) -- 2.7.4
