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
