virtio_net: replace netdev_alloc_skb_ip_align() with napi_alloc_skb()
(2016-03-17 17:42:00 +0200)
----------------------------------------------------------------
virtio/vhost: new features, performance improvements, cleanups
This adds basic polling support for vhost.
Reworks virtio to optionally use DMA API, fixing it on Xen.
Balloon stats gained a new entry.
Using the new napi_alloc_skb speeds up virtio net.
virtio blk stats can now be read while another VCPU
us busy inflating or deflating the balloon.
Plus misc cleanups in various places.
