[dpdk-dev] [PATCH v3 0/6] vhost: improve ready state

[Wang, Yinan]

Hi Matan,

In our daily regression test, we found this patch set will decrease virtio performance and causes virtio interrupt not working properly in multi queue scenarios.  
Could you help to take a look?
Details in Bugzilla  https://bugs.dpdk.org/show_bug.cgi?id=507, btw, pls use low qemu version(qemu<4.1) to reproduce the second issue since the case blocked by one qemu bug with high qemu version.

BR,
Yinan
