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.

Now that we disable any receiver whose queue is full, we do not require senders to handle a zero return by supplying a sent callback. This is a second step towards allowing can_receive() handlers to return true even if no buffer space is available.

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.

commit 71f4effc Author: Alexander Graf <agraf@suse.de> Date: Fri Oct 30 22:27:00 2009 +0100 Unbreak tap compilation on OS X Broke the build on Linux due to a bad #if guard Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

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.

Okay, this makes the tap options available on AIX even though there's no support, but if we want to do it right we should have not compile the tap code at all on AIX using e.g. CONFIG_TAP. Signed-off-by: NMark McLoughlin <markmc@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
