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.
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
