Subject: [Qemu-devel] [PATCH V4 13/19] virtio-pci: switch to use bus specific queue limit
Date: Wed, 18 Mar 2015 17:35:03 +0800 [thread overview]
Message-ID: <1426671309-13645-14-git-send-email-jasowang@redhat.com> (raw)
In-Reply-To: <1426671309-13645-1-git-send-email-jasowang@redhat.com>
Instead of depending on a macro, switch to use a bus specific queue
limit.
