[PULL net-next] macvtap, vhost and virtio tools updates

["Michael S. Tsirkin" <mst@redhat.com>]

There are mostly bugfixes here.
I hope to merge some more patches by 3.5, in particular
vlan support fixes are waiting for Eric's ack,
and a version of tracepoint patch might be
ready in time, but let's merge what's ready so it's testable.

This includes a ton of zerocopy fixes by Jason -
good stuff but too intrusive for 3.4 and zerocopy is experimental
anyway.

virtio supported delayed interrupt for a while now
so adding support to the virtio tool made sense

Please pull into net-next and merge for 3.5.
Thanks!
