[dpdk-dev] doc: announce renaming of ethdev library

  The right name of ethdev should be dpdk_netdev. However:
1/ We are using rte_ prefix in the code and library names.
2/ The API uses rte_ethdev
That's why 16.11 will just have the rte_ prefix prepended to
the library filename as every other libraries.

Hi Thomas,
just my two cents as Ubuntu DPDK maintainer (and part of the Debian Team
that does the same).
(Yeah I really could reuse it three times :-) )

It will be a bit of effort to adapt, but should be no rocket-science.
I like that eventually the namespace will be cleaner.

Just curious, do we already know by looking ahead if ethdev will get an ABI
bump anyway?
So will the transition be:
a) libethdev4 -> librte_ethdev5
b)libethdev4 -> librte_ethdev4
If it is b) would/should one provide a compat symlink then in your Opinion?

Anyway, for now I think it is fair to say:

Good point.
We'll make a symlink if the version stay the same.
Maybe it will be bumped because of a rework of the hotplug API.
