[PATCH net-next 0/5] refine virtio-net XDP
Hi:
This series brings two optimizations for virtio-net XDP:
- avoid reset during XDP set
- turn off offloads on demand
Please review.
Thanks
Jason Wang (5):
virtio_ring: allow to store zero as the ctx
virtio-net: pack headroom into ctx for mergeable buffer
virtio-net: switch to use new ctx API for small buffer
virtio-net: do not reset during XDP set
virtio-net: switch off offloads

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