Steps to build PMD and to run sample application are common among
drivers. So those instructions can be moved to a new file. It is
possible to include this file in driver documentations or be referred
using a label.

1. Introduce new doc file.
2. Make use of the file in liquidio

Current ethdev always stores MAC address even it fails to be added.
Other function may regard the failed MAC address valid and lead to
some errors. So There is a need to check if the addr is added
successfully or not and discard it if it fails.

Now DPDK vhost lib has been generic enough, that it can be used to
implement any vhost-user drivers.
For example, this patch implements a very simple vhost-user net driver,
mainly for demonstrating how to use those generic vhost APIs.
And when the --builtin-net-driver option is used, the example
It doesn't make any sense to invoke destroy_device() callback at

We used to use rte_vhost_driver_session_start() to trigger the vhost-user
session. It takes no argument, thus it's a global trigger. And it could
be problematic.
The issue is, currently, rte_vhost_driver_register(path, flags) actually
tries to put it into the session loop (by fdset_add). However,
rte_mbuf struct is something more likely will be used only in vhost-user
net driver, while we have made vhost-user generic enough that it can
be used for implementing other drivers (such as vhost-user SCSI), they
have also include . Otherwise, the build will be broken.
We could workaround it by us

The queue pair is very virtio-net specific, other devices don't have

We used to use rte_vhost_get_queue_num() for telling how many vrings.
