Revert "sch_netem: Remove classful functionality"
Many users have wanted the old functionality that was lost
to be able to use pfifo as inner qdisc for netem. The reason that
netem could not be classful with the older API was because of the
limitations of the old dequeue/requeue interface; now that qdisc API has
a peek function, there is no longer a problem with using any
inner qdisc's.

ipv4: Rearrange how ip_route_newports() gets port keys.
ip_route_newports() is the only place in the entire kernel that
cares about the port members in the routing cache entry's lookup
flow key.
Therefore the only reason we store an entire flow inside of the
struct rtentry is for this one special case.
Rewrite ip_route_newports() such that:
1) The caller passes in the original port values, so we don't need
to use the rth->fl.fl_ip_{s,d}port values to remember them.
2) The lookup flow is constructed by hand instead of being copied
from the routing cache entry's flow.

Implemented igb_ndo_set_vf_bw function which is being used

The rate limitation can be configured only when the link is up.
The rate limit value can be ranged between 0 and actual
link speed measured in Mbps. A value of '0' disables the rate limit for
this specific VF.
iproute2 usage will be 'ip link set ethX vf Y rate Z'.
After the command is made, the rate will be changed instantly.
To view the current rate limit, use 'ip link show ethX'.
The rates will be zeroed only upon driver reload or a link speed change.

tipc: Fix port counter handling to correct congestion control
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.

r6040: fix multicast operations
The original code does not work well when the number of mulitcast
address to handle is greater than MCAST_MAX. It only enable promiscous
mode instead of multicast hash table mode, so the hash table function
will not be activated and all multicast frames will be recieved in this
condition.
This patch fixes the following issues with the r6040 NIC operating in
multicast:
1) When the IFF_ALLMULTI flag is set, we should write 0xffff to the NIC
hash table registers to make it process multicast traffic.
2) When the number of multicast address to handle is smaller than
MCAST_MAX, we should use the NIC multicast registers MID1_{L,M,H}.
3) The hashing of the address was not correct, due to an invalid
substraction (15 - (crc & 0x0f)) instead of (crc & 0x0f) and an
incorrect crc algorithm (ether_crc_le) instead of (ether_crc).
4) If necessary, we should set HASH_EN flag in MCR0 to enable multicast
hash table function.

net_sched: SFB flow scheduler
This is the Stochastic Fair Blue scheduler, based on work from :
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 :
http://thread.gmane.org/gmane.linux.network/90225
http://thread.gmane.org/gmane.linux.network/90375
Default flow classifier is the rxhash introduced by RPS in 2.6.35, but
we can use an external flow classifier if wanted.
tc qdisc add dev $DEV parent 1:11 handle 11: \
est 0.5sec 2sec sfb limit 128
tc filter add dev $DEV protocol ip parent 11: handle 3 \
flow hash keys dst divisor 1024
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
