While I'm looking into how to account standard tx counters on XDP tx
processing, I found several bugs around XDP tx and napi_tx.
Patch1: Fix oops on error path. Patch2 depends on this.
Patch2: Fix memory corruption on freeing xdp_frames with napi_tx enabled.
Patch3: Minor fix patch5 depends on.
Patch4: Fix memory corruption on processing xdp_frames when XDP is disabled.
Also patch5 depends on this.
Patch5: Fix memory corruption on processing xdp_frames while XDP is being
disabled.
Patch6: Minor fix patch7 depends on.
Patch7: Fix memory corruption on freeing sk_buff or xdp_frames when a normal
queue is reused for XDP and vise versa.
v2:
- patch5: Make rcu_assign_pointer/synchronize_net conditional instead of
_virtnet_set_queues.
- patch7: Use napi_consume_skb() instead of dev_consume_skb_any()

virtio_net: Don't enable NAPI when interface is down
virtio_net: Don't call free_old_xmit_skbs for xdp_frames
virtio_net: Fix not restoring real_num_rx_queues
virtio_net: Fix out of bounds access of sq
virtio_net: Don't process redirected XDP frames when XDP is disabled
virtio_net: Use xdp_return_frame to free xdp_frames on destroying vqs
virtio_net: Differentiate sk_buff and xdp_frame on freeing
