Eliminates TIPC's prototype support for message sequence numbering
on routable connections (i.e. connections requiring more than one hop).
This capability isn't currently used, and can be removed since TIPC
only supports systems in which all inter-node communication can be
achieved in a single hop.

Modifies TIPC's congestion control between a connected port and its
peer so that it works as documented. The following changes have been
made:
1) The counter of the number of messages sent by a port now starts
at zero, rather than one. This prevents the port from reporting port
congestion one message earlier than it was supposed to.
2) The counter of the number of messages sent by a port is now
incremented only if a non-empty message is sent successfully.
This prevents the port from becoming permanently congested if
too many send attempts are unsuccessful because of congestion
(or other reasons). It also removes the risk that empty hand-
shaking messages used during connection setup might cause the
port to report congestion earlier than it was supposed to.
3) The counter of the number of unacknowledged messages received by
a port controlled by an internal TIPC service is now incremented
only if the message is non-empty, in order to be consistent with
the aforementioned changes.

W. Feng, D. Kandlur, D. Saha, K. Shin. Blue: A New Class of Active Queue
Management Algorithms. U. Michigan CSE-TR-387-99, April 1999.
http://www.thefengs.com/wuchang/blue/CSE-TR-387-99.pdf
This implementation is based on work done by Juliusz Chroboczek
General SFB algorithm can be found in figure 14, page 15:
B[l][n] : L x N array of bins (L levels, N bins per level)
enqueue()
Calculate hash function values h{0}, h{1}, .. h{L-1}
Update bins at each level
for i = 0 to L - 1
if (B[i][h{i}].qlen > bin_size)
B[i][h{i}].p_mark += p_increment;
else if (B[i][h{i}].qlen == 0)
B[i][h{i}].p_mark -= p_decrement;
p_min = min(B[0][h{0}].p_mark ... B[L-1][h{L-1}].p_mark);
if (p_min == 1.0)
ratelimit();
else
mark/drop with probabilty p_min;
I did the adaptation of Juliusz code to meet current kernel standards,
and various changes to address previous comments :

tc filter add dev $DEV protocol ip parent 11: handle 3 \

Notes:
1) SFB default child qdisc is pfifo_fast. It can be changed by another
qdisc but a child qdisc MUST not drop a packet previously queued. This
is because SFB needs to handle a dequeued packet in order to maintain
its virtual queue states. pfifo_head_drop or CHOKe should not be used.
2) ECN is enabled by default, unlike RED/CHOKe/GRED

Assigning a socket in timewait state to skb->sk can trigger

if (skb->sk) {
read_lock_bh(&skb->sk->sk_callback_lock);
if (skb->sk->sk_socket && skb->sk->sk_socket->file) ...
in the timewait case, accessing sk->sk_callback_lock and sk->sk_socket
is invalid.
Either all of these spots will need to add a test for sk->sk_state != TCP_TIME_WAIT,
or xt_TPROXY must not assign a timewait socket to skb->sk.
This does the latter.
If a TW socket is found, assign the tproxy nfmark, but skip the skb->sk assignment,
thus mimicking behaviour of a '-m socket .. -j MARK/ACCEPT' re-routing rule.
The 'SYN to TW socket' case is left unchanged -- we try to redirect to the

this is a similar feature to 'n-tuple' flow steering through the
ethtool API, test the same feature flag that controls that.
