Subject: [RFC PATCH net-next 0/9] gve: Implement netdev queue api

Following the discussion on
https://patchwork.kernel.org/project/linux-media/patch/20240305020153.2787423-2-almasrymina@google.com/,
the queue api defined by Mina is implemented for gve.

The first patch is just Mina's introduction of the api. The rest of the
patches make surgical changes in gve to enable it to work correctly with
only a subset of queues present (thus far it had assumed that either all
queues are up or all are down). The final patch has the api
implementation.

Mina Almasry (1):
  queue_api: define queue api

Shailend Chand (8):
  gve: Make the RX free queue funcs idempotent
  gve: Add adminq funcs to add/remove a single Rx queue
  gve: Make gve_turn(up|down) ignore stopped queues
  gve: Make gve_turnup work for nonempty queues
  gve: Avoid rescheduling napi if on wrong cpu
  gve: Reset Rx ring state in the ring-stop funcs
  gve: Account for stopped queues when reading NIC stats
  gve: Implement queue api
