spapr_llan: fix device reenabling
Normally, the "tap" device is polled by QEMU if a guest NIC can receive packets. If a guest NIC is stopped during transfer (rmmod or ifdown), it may still have packets in a queue which have to be send to the guest before QEMU enables polling of a "tap" interface via tap_update_fd_handler(). However the spapr_llan device was missing the qemu_flush_queued_packets() call so the tap_send_completed() callback was never called and therefore "tap" interface polling was not enabled ever. The patch fixes this problem. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>
