This series introduces a new HXPS Tx mode alognside existing
XPS and static modes. The goal is to provide a mode where all
the transmit queues are used, whatever the number of PMD
threads. This may be used with Vhost-user ports, where the
guest application driving the Virtio device expects packets
to be distributed on all the queues.
As a preliminary step, in order to be able to validate the
feature at OVS level, the first patch introduces per-queue
basic statistics for Vhost-user ports. This patch is
complementary to David's patch [0] adding per-queue
statistics to DPDK ports using xstats.

The series also introduces two DPDK tests for Vhost-user
multiqueue, with and without HXPS enabled.
I also forgot to mention that this series depends on David's
system-dpdk tests refactoring series:
