This does resolve the problem.
Thank you so much.

Subject: Re: [dpdk-dev] Can not init NIC after merge to DPDK 1.7 problem
We ran into a similar problem when migrating to 1.7.
Here are the subtle flags, in dpdk/mk/rte.app.mk, that we needed:
LDLIBS += --whole-archive
...
LDLIBS += --no-whole-archive
This apparently tells the linker to pull in whole archive(s), even if it
thinks that we don't need all objects.
