Packed ring format is imported since virtio spec 1.1. All descriptors
are compacted into one single ring when packed ring format is on. It is
straight forward that ring operations can be accelerated by utilizing
SIMD instructions. 

This patch set will introduce vectorized data path in vhost library. If
vectorized option is on, operations like descs check, descs writeback,
address translation will be accelerated by SIMD instructions. Vhost
application can choose whether using vectorized acceleration, it is 
like external buffer and zero copy features. 

If platform or ring format not support vectorized function, vhost will
fallback to use default batch function. There will be no impact in current
data path.

Marvin Liu (5):
  vhost: add vectorized data path
  vhost: reuse packed ring functions
  vhost: prepare memory regions addresses
  vhost: add packed ring vectorized dequeue
  vhost: add packed ring vectorized enqueue
