Both myself and Thomas always run checkpatch against patches before applying them.

Clang gives a compile error after applying this patchset. Please investigate.

== Build drivers/net/qede
  CC base/ecore_dev.o
fatal error: unknown warning option '-Wno-shift-negative-value'; did you mean
      '-Wno-shift-sign-overflow'? [-Wunknown-warning-option]
/home/bruce/next-net/dpdk-next-net/mk/internal/rte.compile-pre.mk:126: recipe for target 'base/ecore_dev.o' failed

This is seen with clang 3.6 on Fedora 23.
	"clang version 3.6.0 (tags/RELEASE_360/final)"


Similarly, 32-bit (i686) build fails:

== Build drivers/net/qede
  CC base/ecore_dev.o
/home/bruce/next-net/dpdk-next-net/drivers/net/qede/base/ecore_dev.c: In function ‘ecore_chain_alloc_sanity_check’:
/home/bruce/next-net/dpdk-next-net/drivers/net/qede/base/ecore_dev.c:2571:32: error: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 6 has type ‘u64 {aka long long unsigned int}’ [-Werror=format=]
compilation terminated due to -Wfatal-errors.
cc1: all warnings being treated as errors

This is seen with gcc 5.3.1 on Fedora 23.
