Browse Source

the compiler macros, so we can remove them and just use the compiler
versions directly.

* build macros: The macros defining RTE_MACHINE_CPUFLAG_* will be removed
from the build. The information provided by these macros is available
through standard compiler macros. For example, RTE_MACHINE_CPUFLAG_SSE3
duplicates the compiler-provided macro __SSE3__.
* kvargs: The function ``rte_kvargs_process`` will get a new parameter
for returning key match count. It will ease handling of no-match case.
