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.

slirp: Make hostfwd_add/remove multi-instance-aware
Extend the syntax of hostfwd_add/remove to optionally take a tuple ofVLAN ID and slirp stack name. If those are omitted, the commands willcontinue to work on the first registered slirp stack.

slirp: Kill slirp_is_inited
Avoid the need for slirp_is_inited by refactoring the protectedslirp_select_* functions. This also avoids the clearing of all fd setson select errors.
slirp: Add info usernet for dumping connection states

slirp: Rework monitor commands for host forwarding
Improve the monitor interface for adding and removing host forwardingrules by splitting it up in two commands and rename them to hostfwd_addand hostfwd_remove. Also split up the paths taken for legacy -redir...
slirp: Bind support for host forwarding rules
Extend the hostfwd rule format so that the user can specify on whichhost interface qemu should listen for incoming connections. If omitted,binding will takes place against all interfaces.
slirp: Move smb, redir, tftp and bootp parameters and -net channel
So far a couple of slirp-related parameters were expressed viastand-alone command line options. This it inconsistent and unintuitive.Moreover, it prevents both dynamically reconfigured (host_net_add/...
qemu/net: flag to control the number of vectors a nic has
Add an option to specify the number of MSI-X vectors for PCI NIC cards. Thiscan also be used to disable MSI-X, for compatibility with old qemu. Thisoption currently only affects virtio cards.

net: add qemu_purge_queued_packets()
If net client sends packets asynchronously, it needs to purge its queuedpackets in cleanup() so as to prevent sent callbacks being invoked witha freed client.

net: add packet length to NetPacketSent callback
virtio-net needs this - for the same purpose that it currently uses thereturn value from qemu_sendv_packet().
Support addr=... in option argument of -net nic
Make net_client_init() accept addr=, put the value into structNICinfo. Use it in pci_nic_init(), and remove arguments bus anddevfn.
Don't support addr= in third argument of monitor command pci_add,because that clashes with its first argument. Admittedly unelegant....
Make nic option rom loading less painful.
The code how it is today, is totally painful to read and keep.To begin with, the code is duplicated with the option rom loadingcode that linux_boot and vga are already using.
This patch introduces a "bootable" state in NICInfo structure,...
net: add qemu_send_packet_async()
Add a qemu_send_packet() variant which will queue up the packetif it cannot be sent when all client queues are full. It laterinvokes the supplied callback when the packet has been sent.
If qemu_send_packet_async() returns zero, the caller is expected...
net: Improve parameter error reporting
As host network devices can also be instantiated via the monitor, errorsshould then be reported to the related monitor instead of stderr. Thisrequires larger refactoring, so this patch starts small with introducing...
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().
Signed-off-by: Mark McLoughlin <markmc@redhat.com>
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.
User Networking: Enable removal of redirections
Using the new host_net_redir command you can easily create redirectionson the fly while your VM is running.
While that's great, it's missing the removal of redirections, in case youwant to have a port closed again at a later point in time....
