[PATCH 0/5] virtio_net: Add MAC and VLAN filtering

[Alex Williamson <alex.williamson@hp.com>]

This series enables setting the virtio-net device MAC address, adds
infrastructure for the new control virtqueue, and makes use of it
to support set_rx_mode, unicast and multicast address lists, and
supporting a hypervisor based VLAN filter.  The goal is to make the
virtio-net device support more of the features of a physical NIC and
allow the hypervisor to discard packets we're not interested in.

This version incorporates the review comments from Mark McLoughlin,
specifically, much improved comments and commit logs, verifying the
functionality of host not providing a MAC address, moving communication
structs into virtio_net.h, adding warnings when things don't work, and
making the strings grep'able.  I've left the class/cmd split in the
control header rather than consolidating it into a single value, I'm
hoping I've made sufficient arguments for that.  Also, I left the
error return rather than a BUG_ON in send_command because I can't
conditionally enable set_rx_mode as it's in a const struct.  Instead,
I've changed the caller to avoid the issue.  Please comment and/or
apply.  Thanks,

Alex
