From 923e2d98ede7404882656aeb4364c3964a95db3d Mon Sep 17 00:00:00 2001 From: Yuanhan Liu Date: Fri, 13 Nov 2015 15:24:09 +0800 Subject: vhost: let SET_VRING_ENABLE message depends on protocol feature But not depend on PROTOCOL_F_MQ feature bit. So that we could use SET_VRING_ENABLE to sign the backend on stop, even if MQ is disabled. That's reasonable, since we will have one queue pair at least.
