[Bug 1556306] Re: vhost-user: qemu stops processing packets under high load of traffic

Hi, cleaning up old issues. In all the time we had no confirmed report on trusty, also as serge outlined in c#19 the backport would be much harder and therefore carry more risk for the SRU. Since wily was haniging in verification so long and now is EOD this is dead. I'm cleaning up the bug

[Bug 1556306] Re: vhost-user: qemu stops processing packets under high load of traffic

The wily SRU has been waiting for validation for quite some time. I'm wondering whether that is because noone is using wily, or because it's not high priority? The patch does not apply cleanly to trusty. In particular, the chunk in ./hw/net/vhost_net.c.rej is quite obsolete in the trusty
