* Per http://www.open-mpi.org/community/lists/devel/2013/12/13504.php, protect usage of struct ifreq->ifr_hwaddr * Per http://www.open-mpi.org/community/lists/devel/2013/12/13503.php, avoid #define conflict with the token "if_mtu" * Also fix some whitespace and string naming issues in opal/util/if.c Tested by Paul Hargrove.
