Mark McLoughlin 70783b9c9b net: add receive_raw parameter to qemu_new_vlan_client()
Trivial patch to allow supplying a receive_raw function.

A future cleanup should combine this function pointer parameters into a
table.

Mark McLoughlin bb6e636443 net: add a client type code
This is so as to allow APIs which operate on specific client types
without having to add a function table entry which is only implemented
by a single client type.

Mark McLoughlin 283c7c63f5 net: allow NICs to be connected to netdevs
Introduce a 'peer' member to VLANClientState as an alternative
to a vlan. The idea being that packets are transfered directly
from peer clients rather than going through a vlan.

Jan Kiszka 1a60952027 net: Provide VLAN client lookup helper
Introduce qemu_find_vlan_client_by_name for VLANClientState lookup based
on VLAN ID and client name. This is useful for monitor commands.

Gerd Hoffmann 3e3cabcff9 xen nic: check tx queue after connect.
Needed for savevm/loadvm + migration: In that case the queue might
already have packets on (re-)connect.  The guest wouldn't notify us
because notifications are only sent when stuffing a packet into an
empty queue.

Mark McLoughlin cda9046ba7 net: re-name vc->fd_read() to vc->receive()
VLANClientState's fd_read() handler doesn't read from file
descriptors, it adds a buffer to the client's receive queue.

Re-name the handlers to make things a little less confusing.

Mark McLoughlin 463af5349a net: add fd_readv() handler to qemu_new_vlan_client() args
This, apparently, is the style we prefer - all VLANClientState
should be an argument to qemu_new_vlan_client().

aliguori e613b064a8 xen: add net backend driver. (Gerd Hoffmann)
This patch adds a network interface backend driver to qemu.  It is a pure
userspace implemention using the gntdev interface.  It uses "qnet" as
backend name in xenstore so it doesn't interfere with the netback
backend (aka "vnif").

The network backend is hooked into the corrosponding qemu vlan, i.e.
vif 0 is hooked into vlan 0.  To make the packages actually arrive
somewhere you additionally have to link the vlan to the outside world
using the usual qemu command line options such as "-net tap,...".
