Subject: [PATCH net-next 0/6] Basic XDP Support for DQO RDA Queue Format

From: Joshua Washington <joshwash@...gle.com>

This patch series updates the GVE XDP infrastructure and introduces
XDP_PASS and XDP_DROP support for the DQO RDA queue format.

The infrastructure changes of note include an allocation path refactor
for XDP queues, and a unification of RX buffer sizes across queue
formats.

This patch series will be followed by more patch series to introduce
XDP_TX and XDP_REDIRECT support, as well as zero-copy and multi-buffer
support.

Joshua Washington (6):
  gve: remove xdp_xsk_done and xdp_xsk_wakeup statistics
  gve: introduce config-based allocation for XDP
  gve: update GQ RX to use buf_size
  gve: merge packet buffer size fields
  gve: update XDP allocation path support RX buffer posting
  gve: add XDP DROP and PASS support for DQ
