Subject: [Qemu-devel] [PATCH 1/2] vhost: let SET_VRING_ENABLE message depends on protocol feature
Date: Fri, 13 Nov 2015 15:24:09 +0800 [thread overview]
Message-ID: <1447399450-29489-1-git-send-email-yuanhan.liu@linux.intel.com> (raw)
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.
