Thanks for that input. If we drop support for Centos/RHEL 7, I think we
should be ok to pass -std=c11 for the build of DPDK.

Have you any thoughts on the second part of the c11 move - where our
headers require c11 support and therefore may require that the end user
builds their own code using -std=c11? This latter part is the bit that
concerns me a little, as I feel it may be problematic for some with older
codebases.
