Subject: [PATCH net v2 0/6] virtio-net: Fix and update interrupt moderation

The setting of virtio coalescing parameters involves all-queues and
per queue, so we must be careful to synchronize the two.

Regarding napi_tx switching, this patch set is not only
compatible with the previous way of using tx-frames to switch napi_tx,
but also improves the user experience when setting interrupt parameters.

This patch set has been tested and was part of the previous netdim patch
set[1] and is now being split to be rolled out in steps.
