[dpdk-dev] compile error with linuxapp-clang target on Fedora 20 with 3.15.10 kernel

[Matthew Hall]

I fixed one main libs bug which blocked compile that was trivial and got it applied. I had examples working too but using an impolite method of doing so.

As for the latest kernel stuff, it sounds like we have to get a hand from LKML or a sublist to figure it out, eh? Doesn't seem like it's in the DPDK code.

Matthew.
