Add option to compute and send SHA256 over data sent (-i). This is to ensure the correctness of data received. Data is randomly populated from /dev/urandom. Tested: ./tcp_mmap -s -z -i ./tcp_mmap -z -H $ADDR -i SHA256 is correct ./tcp_mmap -s -i ./tcp_mmap -H $ADDR -i SHA256 is correct Signed-off-by: Coco Li <lixiaoyan@google.com> Reviewed-by: Eric Dumazet <edumazet@google.com> Link: https://lore.kernel.org/r/20230321081202.2370275-2-lixiaoyan@google.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
