Subject: [PATCH net-next v2 0/5] gve: AF_XDP zero-copy for DQO RDA

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

This patch series adds support for AF_XDP zero-copy in the DQO RDA queue
format.

XSK infrastructure is updated to re-post buffers when adding XSK pools
because XSK umem will be posted directly to the NIC, a departure from
the bounce buffer model used in GQI QPL. A registry of XSK pools is
introduced to prevent the usage of XSK pools when in copy mode.

v2:
  - Remove instance of unused variable
v1: https://lore.kernel.org/netdev/20250714160451.124671-1-jeroendb@google.com/

Joshua Washington (5):
  gve: deduplicate xdp info and xsk pool registration logic
  gve: merge xdp and xsk registration
  gve: keep registry of zc xsk pools in netdev_priv
  gve: implement DQO TX datapath for AF_XDP zero-copy
  gve: implement DQO RX datapath and control path for AF_XDP zero-copy
