This adds vhost binary option to tap, to enable vhost net accelerator. Default is off for now, we'll be able to make default on long term when we know it's stable. vhostfd option can be used by management, to pass in the fd. Assigning vhostfd implies vhost=on.

Right now, downscript is not invoked reliably. If you execute 'quit' from the monitor, it won't be invoked. This fixes that by converting tap to use an exit_notifier to execute the downscript. In this case, allowing an exit notifier to include state is critically important for the conversion. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

error_report() terminates the message with a newline. Strip it it from its arguments. This fixes a few error messages lacking a newline: net_handle_fd_param()'s "No file descriptor named %s found", and tap_open()'s "vnet_hdr=1 requested, but no kernel support for IFF_VNET_HDR available" (all three versions). There's one place that passes arguments without newlines intentionally: load_vmstate(). Fix it up.

net_check_clients() prints this when an VLAN has host devices, but no guest devices. It uses VLANState members nb_guest_devs and nb_host_devs to keep track of these devices. However, -device does not update nb_guest_devs, only net_init_nic() does that, for -net nic. Check the VLAN clients directly, and remove the counters.

When vhost is bound to a backend device, we need to stop polling it when vhost is started, and restart polling when vhost is stopped. Add an API for that for use by vhost, and implement in tap backend. Signed-off-by: NMichael S. Tsirkin <mst@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Okay, let's try re-enabling the drain-entire-queue behaviour, with a difference - before each subsequent packet, use qemu_can_send_packet() to check that we can send it. This is similar to how we check before polling the tap fd and avoids having to drop a packet if the receiver cannot handle it. This patch should be a performance improvement since we no longer have to go through the mainloop for each packet.

If qemu_send_packet_async() returns zero, it means the packet has been queued and the sent callback will be invoked once it has been flushed. This is only possible where the NIC's receive() handler returns zero and promises to notify the networking core that room is available in its queue again. In the case where the receive handler does not have this capability (and its queue fills up) it returns -1 and the networking core does not queue up the packet. This condition is indicated by a -1 return from qemu_send_packet_async(). Currently, tap handles this condition simply by dropping the packet. It should do its best to avoid getting into this situation by checking such NIC's have room for a packet before copying the packet from the tap interface. tap_send() used to achieve this by only reading a single packet before returning to the mainloop. That way, tap_can_send() is called before reading each packet. tap_send() was changed to completely drain the tap interface queue without taking into account the situation where the NIC returns an error and the packet is not queued. Let's start fixing this by reverting to the previous behaviour of reading one packet at a time.

Currently compiling the tap sources breaks on Mac OS X. This is because of: 1) tap-linux.h requiring Linux includes 2) typos 3) missing #includes This patch adds what's necessary to compile tap happily on Mac OS X. I haven't tested if using tap actually works, but I don't think that's a major issue as that code was probably seriously untested before already. I didn't split the patch, because it's only a few lines of code and splitting is probably not worth the effort here.
