net: convert xen to NICState
Signed-off-by: Mark McLoughlin <markmc@redhat.com>Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
net: move net-checksum.c under net/
Also add a new net/checksum.h header
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.

Update to a hopefully more future proof FSF address

net: Provide VLAN client lookup helper
Introduce qemu_find_vlan_client_by_name for VLANClientState lookup basedon VLAN ID and client name. This is useful for monitor commands.

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.
xen nic: use XC_PAGE_SIZE instead of PAGE_SIZE.

xen nic: use qemu_malloc
xen: net backend doesn't need linux headers.
Drop them to make qemu build on OpenSolaris.

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