From 0a61f3b4782d4dd431c8d6cca6d7fd48d68e1b59 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Fri, 14 Feb 2014 12:27:04 +1100 Subject: spapr-vlan: flush queue whenever can_receive can go from false to true When the guests adds buffers to receive queue, the network device should flush its queue of pending packets. This is done with qemu_flush_queued_packets. This adds a call to qemu_flush_queued_packets() which wakes up the main loop and let QEMU update the network device status which now is "can receive". The patch basically does the same thing as e8b4c68 does.
