xen: flush queue when getting an event
xen does not have a register that, when written, will cause can_receiveto go from false to true. However, flushing the queue can be attemptedwhenever the front-end raises its side of the Xen event channel. There...
net: Rename VLANClientState to NetClientState
The vlan feature is no longer part of net core. Rename VLANClientStateto NetClientState because net clients are not explicitly associated witha vlan at all, instead they have a peer net client to which they are...
net: Rename qemu_del_vlan_client() to qemu_del_net_client()
Another step in moving the vlan feature out of net core. Users onlydeal with NetClientState and therefore qemu_del_vlan_client() should benamed qemu_del_net_client().

xen: Reorganize includes of Xen headers.
Because xs.h will be remove in future release of Xen, this patch removes theextra includes of this headers.
Also, it removes the extra includes of xenctrl.h and xen/io/xenbus.h as therealready are in xen_common.h....

net: move net-checksum.c under net/

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 atable.
net: add a client type code
This is so as to allow APIs which operate on specific client typeswithout having to add a function table entry which is only implementedby a single client type.
net: allow NICs to be connected to netdevs
Introduce a 'peer' member to VLANClientState as an alternativeto a vlan. The idea being that packets are transfered directlyfrom peer clients rather than going through a vlan.

xen nic: check tx queue after connect.
Needed for savevm/loadvm + migration: In that case the queue mightalready have packets on (re-)connect. The guest wouldn't notify usbecause notifications are only sent when stuffing a packet into anempty queue....
net: add fd_readv() handler to qemu_new_vlan_client() args
This, apparently, is the style we prefer - all VLANClientStateshould be an argument to qemu_new_vlan_client().

net: re-name vc->fd_read() to vc->receive()
VLANClientState's fd_read() handler doesn't read from filedescriptors, it adds a buffer to the client's receive queue.
Re-name the handlers to make things a little less confusing.
net: pass VLANClientState* as first arg to receive handlers
Give static type checking a chance to catch errors.
net: add return value to packet receive handler
This allows us to handle queue full conditions rather than droppingthe packet on the floor.
