[dpdk-dev] [PATCH 00/10] Enable DPDK core build with gcc 7

[Bruce Richardson <bruce.richardson@intel.com>]

Since GCC 7 is now yesterday's news :-), I figured we should try and make
DPDK compile successfully with that new version. The main difficulties are
because of new warnings being triggered.

* New warnings for fall-though in case statements
* New warnings for possible truncation using snprintf
* New warnings about uninitialized values.

This set of patches fixes or works around those new issues, fixing a couple of
bugs in the process, so that DPDK can compile using gcc 7.

NOTE: this set only covers the basic DPDK libs, apps and tests. It does not
cover the example apps, which still have issues.
