    Don't treat the packet length as unsigned.
    
    The scanf family of functions are as annoyingly bad at handling unsigned
    numbers as strtoul() is - both of them are perfectly willing to accept a
    value beginning with a negative sign as an unsigned value.  When using
    strtoul(), you can compensate for this by explicitly checking for a '-'
    as the first character of the string, but you can't do that with
    sscanf().
    
    So revert to having pkt_len be signed, and scanning it with %d, but
    check for a negative value and fail if we see a negative value.
