    Fix servicing IPv6 based TCP connections

    When a connection is received via IPv6, the address is a 4-tuple
    instead of a 2-tuple for IPv4, so handle this accordingly.

    Also handle the end of the TCP connection gracefully instead of
    emitting an "Invalid packet" warning every time.
