Linux supports running the RPMsg protocol over the VirtIO transport protocol, but currently there is only support for VirtIO clients and no support for VirtIO servers. This patch adds a vhost-based RPMsg server implementation, which makes it possible to use RPMsg over VirtIO between guest VMs and the host.

This patch adds support for the Mergeable Receive Buffers feature to vhost_net. +-DLS Changes from previous revision: 1) renamed: vhost_discard_vq_desc -> vhost_discard_desc vhost_get_heads -> vhost_get_desc_n vhost_get_vq_desc -> vhost_get_desc 2) added heads as argument to ghost_get_desc_n 3) changed "vq->heads" from iovec to vring_used_elem, removed casts 4)
