Hi all,

Am facing an issue with compilation on redhat 6.5 of DPDK v16.11-rc2,
compilation fails with:

  cc1: warnings being treated as errors

In doc/guides/rel_notes/supported_os.rst we still support
"Red Hat Enterprise Linux 6.5".

Do we still want to support it, or should we update the documentation to
remove it?
