Hi:
This series implement basic in order feature support for vhost_net. This feature requires both driver and device to use descriptors in order which can simplify the implementation and optimizaton for both side. The series also implement a simple optimization that avoid read available ring. Test shows 10% performance improvement at most.
More optimizations could be done on top.
Changes from V1: - no code changes - add result of SMAP off
Jason Wang (3): virtio: introduce in order feature bit vhost_net: support in order feature vhost: don't touch avail ring if in_order is negotiated
