2011-02-20vhost: disable on tap link downMichael S. Tsirkin
qemu makes it possible to disable link at tap which is not communicated to the guest but causes all packets to be dropped. When vhost-net is enabled, vhost needs to be aware of both the virtio link_down and the peer link_down. we switch to userspace emulation when either is down. Signed-off-by: Michael S.

2011-02-20e1000: verify we have buffers, upfrontMichael S. Tsirkin
The spec says: Any descriptor with a non-zero status byte has been processed by the hardware, and is ready to be handled by the software. Thus, once we change a descriptor status to non-zero we should never move the head backwards and try to reuse this descriptor from hardware. This actually happened with a multibuffer packet that arrives when we don't have enough buffers. Fix by checking that we have enough buffers upfront so we never need to discard the packet midway through. Signed-off-by: Michael S.

2011-02-20e1000: clear EOP for multi-buffer descriptorsMichael S. Tsirkin
The e1000 spec says: if software statically allocates buffers, and uses memory read to check for completed descriptors, it simply has to zero the status byte in the descriptor to make it ready for reuse by hardware. This is not a hardware requirement (moving the hardware tail pointer is), but is necessary for performing an in–memory scan. Thus the guest does not have to clear the status byte. In case it doesn't we need to clear EOP for all descriptors except the last. While I don't know of any such guests, it's probably a good idea to stick to the spec. Signed-off-by: Michael S.

e1000 supports multi-buffer packets larger than rxbuf_size.
