[PATCH net-next V2 0/5] Refine virtio-net XDP

Show all headers | View raw

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
