These patches are against dpdk-net-next/master because
that is where previous patches have already been merged.

Stephen Hemminger (5):
  bus/vmbus: add devargs support
  net/netvsc: allow tuning latency with devargs
  net/netvsc: exhausting transmit descriptors is not an error
  net/netvsc: implement link state change callback
  net/netvsc: integrated VF support

A highlevel question, since netvsc PMD is upstreamed, can we remove vdev_netvsc one?

No.

There are some use cases that still need bifurcated model. And also netvsc PMD
is still in experimental state and vdev_netvsc/failsafe/tap are more stable.

I hope maybe by 19.11?

19.11 would be reasonnable target to deprecate vdev_netvsc.

Series applied to dpdk-next-net/master, thanks.

(checkpatches.sh update dropped from patch, devarg syntax in function comment
updated.)
