tcp buffer limitation: per-cgroup limit
This patch uses the "tcp.limit_in_bytes" field of the kmem_cgroup to
effectively control the amount of kernel memory pinned by a cgroup.
This value is ignored in the root cgroup, and in all others,
caps the value specified by the admin in the net namespaces'
view of tcp_sysctl_mem.
If namespaces are being used, the admin is allowed to set a
value bigger than cgroup's maximum, the same way it is allowed
to set pretty much unlimited values in a real box.

The goal of this work is to move the memory pressure tcp

To avoid excessive overhead in the network fast paths,
the code that accounts allocated memory to a cgroup is
hidden inside a static_branch(). This branch is patched out

penalty should be seen.

xen-netfront: delay gARP until backend switches to Connected
After a guest is live migrated, the xen-netfront driver emits a gratuitous
ARP message, so that networking hardware on the target host's subnet can
take notice, and public routing to the guest is re-established. However,
if the packet appears on the backend interface before the backend is added
to the target host's bridge, the packet is lost, and the migrated guest's
peers become unable to talk to the guest.
A sufficient two-parts condition to prevent the above is:
(1) ensure that the backend only moves to Connected xenbus state after its
hotplug scripts completed, ie. the netback interface got added to the
bridge; and
(2) ensure the frontend only queues the gARP when it sees the backend move
to Connected.
These two together provide complete ordering. Sub-condition (1) is already
satisfied by commit
f942dc2552b8 in Linus' tree, based on commit
6b0b80ca7165 from [1].
In general, the full condition is sufficient, not necessary, because,
according to [2], live migration has been working for a long time without
satisfying sub-condition (2). However, after
6b0b80ca7165 was backported
to the RHEL-5 host to ensure (1), (2) still proved necessary in the RHEL-6
guest. This patch intends to provide (2) for upstream.

sch_red: Adaptative RED AQM
Adaptative RED AQM for linux, based on paper from Sally FLoyd,
Ramakrishna Gummadi, and Scott Shenker, August 2001 :
http://icir.org/floyd/papers/adaptiveRed.pdf
Goal of Adaptative RED is to make max_p a dynamic value between 1% and
50% to reach the target average queue : (max_th - min_th) / 2
Every 500 ms:
if (avg > target and max_p <= 0.5)
increase max_p : max_p += alpha;
else if (avg < target and max_p >= 0.01)
decrease max_p : max_p *= beta;
target :[min_th + 0.4*(min_th - max_th),
min_th + 0.6*(min_th - max_th)].
alpha : min(0.01, max_p / 4)
beta : 0.9
max_P is a Q0.32 fixed point number (unsigned, with 32 bits mantissa)
Changes against our RED implementation are :
max_p is no longer a negative power of two (1/(2^Plog)), but a Q0.32
fixed point number, to allow full range described in Adatative paper.
To deliver a random number, we now use a reciprocal divide (thats really
a multiply), but this operation is done once per marked/droped packet
when in RED_BETWEEN_TRESH window, so added cost (compared to previous
AND operation) is near zero.
dump operation gives current max_p value in a new TCA_RED_MAX_P
attribute.
Example on a 10Mbit link :
tc qdisc add dev $DEV parent 1:1 handle 10: est 1sec 8sec red \
limit 400000 min 30000 max 90000 avpkt 1000 \

ath9k: use config.enable_ani to check if ani should be performed
Currently in ath9k code there is an attempt which is meant to
disable ANI for ar9100 and ar9340. But it doesn't really achieve
this. All it does is disable ANI init and setup (i.e. calls to
ath9k_hw_ani_setup and ath9k_hw_ani_init). Since ath9k_hw_ani_setup is
not called ah->config.ani_poll_interval is never initialized (i.e. it
is always zero) and ath_ani_calibrate always executes ANI procedures
(over uninitialized ANI parameters).
Moreover, ath_ani_calibrate is being called each 1ms because
common->ani.timer is set to zero interval because
ah->config.ani_poll_interval==0 (and thus smallest value of all
intervals). Normally it should not be called this often.
This patch changes the code so config.enable_ani is used to check if
ANI should be performed.
config.enable_ani is initialized to true by default. This patch sets
it to false for ar9100 and ar9340.
