Hello,

contrib\apps\ping\ping.c
line 168:
    if (from.sin_family == AF_INET) {
        LWIP_DEBUGF( PING_DEBUG, ("ping: invalid sin_family\n"));
      }

It causes ("ping: invalid sin_family\n") message for IPv4, what is wrang.

It should be something like this (if supported/tested only IPv4):
      if (from.sin_family != AF_INET) {
        /* So far, supported only IPv4*/
        LWIP_DEBUGF( PING_DEBUG, ("ping: invalid sin_family\n"));
      }

Best regards,
Andrey Butok
