    You do not even need patches for it. You can do it as well with a TBF
    filter in the qdisc and a u32 filter that selects RSTs (it is even a
    standard example in iproute2)

    Another way that may work is to set the send buffer of tcp_socket in
    tcp_ipv4.c to a really small value, so that only one RST packet fits.
    Then you get a good load limit implicitely in the stack
    (there should be probably a sysctl for that)
