[PATCH net-next 0/3] Multiqueue support for virtio-net
...essing Rusty's comments:
- align the implementation (location of cvq) to v5.
- fix the style issue.
- use a global refill instead of per-vq one.
- check the VIRTIO_NET_F_RFS before calling virtnet_set_queues()
Addresing Michael's comments
- rename the curr_queue_pairs in virtnet_probe() to max_queue_pairs
- validate the number of queue pairs supported by the device against
VIRTIO_NET_CTRL_RFS_VQ_PAIRS_MIN and VIRTIO_NET_CTRL_RFS_VQ_PAIRS_MAX.
- don't crash when failing to change the number of virtqueues
- don't set the affinity hint when onle single queue is used or there's too much...

[PATCH net-next V2 0/3] rx busy polling support for virtio-net
Hi all:
This series introduces the support for rx busy polling support. This
was useful for reduing the latency for a kvm guest. Patch 1-2
introduces helpers which is used for rx busy polling. Patch 3
implement the main function.
Test was done between a kvm guest and an external host. Two hosts were
connected through 40gb mlx4 cards. With both busy_poll and busy_read are
set to 50 in guest, 1
