I'm talking from a pure distribution perspective here: Requiring to
recompile all DPDK based applications to distribute a bugfix or to
add support for a new PMD is not ideal.

So ideally OVS would have the possibility to link against the shared
library long term.

Towards the PMDs is more straight forward at first so it seems logical
to focus on that first.

A stable API and ABI for librte seems required as well long term as
DPDK does offer shared libraries but I realize that this is a stretch
goal in the initial phase.
