Subject: [PATCH v4 0/4] virtio_net: Add MAC and VLAN filtering

This series adds infrastructure for a 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 don't want.  These
patches are intended for 2.6.30.

This is the 4th and hopefully final revision, incorporating a few
more tweaks from Rusty.  I've renamed VIRTIO_NET_MAX_CTRL_ARGS to
VIRTNET_SEND_COMMAND_SG_MAX and moved it into the c file.  I've
added the flexible 2-dimensional array to virtio_net_ctrl_mac and
cleaned up the code to use it.  I've retained the single scatterlist
parameter and out/in counts for virtnet_send_command() since the
current sg interface doesn't faciliate merging terminated sg[]s
together.  However, this is an internal virtio_net API and can
easily be refined over time, the key is the separate sg entries
for unicast/multicast MACs for the hypervisor ABI.  Thanks,

Alex
