  To: yocto; +Cc: Chunrong Guo

From: Chunrong Guo <b40290@freescale.com>

           *ifconfig/if_index.c (if_nameindex): Remove local variables
           `ifc', `i', `rq_len', `last_len', `ifr', `end', `cur'.
           Add local variables `content', `it', `length', `index'.
           Remove code that uses the SIOCGIFCONF ioctl to get the interfaces
           list.  Parse the PATH_PROCNET_DEV file to fetch the list of
           interfaces.
