 Coverity indicates the following issues in
 `cpukit/libfs/src/ftpfs/tftpDriver.c`:

 '''CID 1506523''' (!#1 of 1):

   Unchecked return value from library (CHECKED_RETURN)
   11. check_return: Calling sendto(tp->socket, send_buf, plen, 0, (struct
 sockaddr *)&tp->farAddress, 16U) without checking return value. This
 library function may fail and return an error code.
