Hi Bruce,

I concern about whether the PMD has all features of librte_vhost,
because librte_vhost provides more features and freedom than ethdev API
provides.
In some cases, user needs to choose limited implementation without
librte_vhost.
I am going to eliminate such cases while implementing the PMD.
But I don't have strong belief that we can remove librte_vhost now.

So how about keeping current separation in next DPDK?
I guess people will try to replace librte_vhost to vhost PMD, because
apparently using ethdev APIs will be useful in many cases.
And we will get feedbacks like "vhost PMD needs to support like this usage".
(Or we will not have feedbacks, but it's also OK.)
Then, we will be able to merge librte_vhost and vhost PMD.

Thanks,
Tetsuya
