  -v, --verbose            verbose mode
  -C, --card <cardno>      use this card for operation
  -A, --accelerator-type=GENWQE|CAPI CAPI is only available for System p
  -V, --version
  -q, --quiet              quiece output
  -c, --count <number>     do multiple memcopies
  -l, --preload <number>   preload multiple ddcb's. (default 1, only for CAPI Card)
  -X, --cpu <cpu>          only run on this CPU
  -D, --debug              create debug data on failure
  -G, --use-sglist         use the scatter gather list
  -n, --nonblocking        use nonblcoking behavior
  -p, --patternfile <filename>]
  -s, --bufsize <bufsize>  default is 4KiB
  -i, --pgoffs_i <offs>    byte offset for input buffer
  -o, --pgoffs_o <offs>    byte offset for output buffer
  -F, --force-compare <output_data.bin>
  -t, --threads <num>      run <num> threads, default is 1
  -Y, --inject-error <err> IN:0x1, OUT:0x2, SIZE:0x4, DDCB:0x8

This utility sends memcopy DDCBs to the application
chip unit. It can be used to check the cards health and/or
to produce stress on the card to verify its correct
function.

Example:
    dd if=/dev/urandom bs=4096 count=1024 of=input_data.bin
    %s -C0 -F -D --patternfile input_data.bin output_data.bin
    echo $?
    diff input_data.bin output_data.bin
    echo $?
