> follow
>
>The behaviour is the same as in the previous commit, but it is much easier to follow
>as the main test code now indicates to the send_and_recv callbacks what stage of the
>test we are at, and resets the packet counter between stages.
>
>This also re-orders the code so that the send and recv callbacks for each stage
>are next to each other, and uses a case statement in the main send_and_recv driver
>for clarity.

>The smb_krb5_send_and_recv_func_forced and smb_krb5_send_and_recv_func
