bonding: Fix corrupted queue_mapping
In the transmit path of the bonding driver, skb->cb is used to
stash the skb->queue_mapping so that the bonding device can set its
own queue mapping. This value becomes corrupted since the skb->cb is
also used in __dev_xmit_skb.
When transmitting through bonding driver, bond_select_queue is
called from dev_queue_xmit. In bond_select_queue the original
skb->queue_mapping is copied into skb->cb (via bond_queue_mapping)
and skb->queue_mapping is overwritten with the bond driver queue.
Subsequently in dev_queue_xmit, __dev_xmit_skb is called which writes
the packet length into skb->cb, thereby overwriting the stashed
queue mappping. In bond_dev_queue_xmit (called from hard_start_xmit),
the queue mapping for the skb is set to the stashed value which is now
the skb length and hence is an invalid queue for the slave device.
If we want to save skb->queue_mapping into skb->cb[], best place is to
add a field in struct qdisc_skb_cb, to make sure it wont conflict with
other layers (eg : Qdiscc, Infiniband...)
This patchs also makes sure (struct qdisc_skb_cb)->data is aligned on 8
bytes :
netem qdisc for example assumes it can store an u64 in it, without
misalignment penalty.
Note : we only have 20 bytes left in (struct qdisc_skb_cb)->data[].
The largest user is CHOKe and it fills it.

ipv4: Add interface option to enable routing of 127.0.0.0/8
Routing of 127/8 is tradtionally forbidden, we consider
packets from that address block martian when routing and do
not process corresponding ARP requests.
This is a sane default but renders a huge address space
practically unuseable.
The RFC states that no address within the 127/8 block should
ever appear on any network anywhere but it does not forbid
the use of such addresses outside of the loopback device in
particular. For example to address a pool of virtual guests
behind a load balancer.
This patch adds a new interface option 'route_localnet'
enabling routing of the 127/8 address block and processing
of ARP requests on a specific interface.
Note that for the feature to work, the default local route
covering 127/8 dev lo needs to be removed.
Example:
$ sysctl -w net.ipv4.conf.eth0.route_localnet=1
$ ip route del 127.0.0.0/8 dev lo table local
$ ip addr add 127.1.0.1/16 dev eth0

net: Reorder initialization in ip_route_output to fix gcc warning
If I build with W=1, for every file that includes <net/route.h>, I get the warning
include/net/route.h: In function 'ip_route_output':
include/net/route.h:135:3: warning: initialized field overwritten [-Woverride-init]
include/net/route.h:135:3: warning: (near initialization for 'fl4') [-Woverride-init]
(This is with "gcc (Debian 4.6.3-1) 4.6.3")
A fix seems pretty trivial: move the initialization of .flowi4_tos
earlier. As far as I can tell, this has no effect on code generation.

virtio-net: fix a race on 32bit arches
commit
3fa2a1df909 (virtio-net: per cpu 64 bit stats (v2)) added a race
on 32bit arches.
We must use separate syncp for rx and tx path as they can be run at the
same time on different cpus. Thus one sequence increment can be lost and

r8169: avoid NAPI scheduling delay.
While reworking the r8169 driver a few months ago to perform the
smallest amount of work in the irq handler, I took care of avoiding
any irq mask register operation in the slow work dedicated user
context thread. The slow work thread scheduled an extra round of NAPI
work which would ultimately set the irq mask register as required,
thus keeping such irq mask operations in the NAPI handler.
It would eventually race with the irq handler and delay NAPI execution
for - assuming no further irq - a whole ksoftirqd period. Mildly a
problem for rare link changes or corner case PCI events.
The race was always lost after the last bh disabling lock had been
removed from the work thread and people started wondering where those
pesky "NOHZ: local_softirq_pending 08" messages came from.
Actually the irq mask register _can_ be set up directly in the slow
work thread.

Since it's guarenteed that we will access the inetpeer if we're trying

tcp: Get rid of inetpeer special cases.
The get_peer method TCP uses is full of special cases that make no
sense accommodating, and it also gets in the way of doing more
reasonable things here.
First of all, if the socket doesn't have a usable cached route, there
is no sense in trying to optimize timewait recycling.
Likewise for the case where we have IP options, such as SRR enabled,
that make the IP header destination address (and thus the destination
address of the route key) differ from that of the connection's
destination address.
Just return a NULL peer in these cases, and thus we're also able to
get rid of the clumsy inetpeer release logic.

Revert "niu: Add support for byte queue limits."
This reverts commit
efa230f2c68abab817f13473077f8d0cc74f43f3.
BQL doesn't work with how this driver currently only takes TX
interrupts every 1/4 of the TX ring. That behavior needs to be fixed,
but that's a larger non-trivial task and for now we have to revert
BQL support as this makes the device currently completely unusable.

The commit
ba27ec66ffeb78cbf fixes the Kconfig of the
driver when built as module allowing to select/unselect
the PCI and Platform modules that are not anymore mutually
exclusive. This patch fixes and guarantees that the driver
builds on all the platforms w/ w/o PCI and when select/unselect

on both the configuration and the pci/pltf registration the
module_init will fail.
v2: set the CONFIG_STMMAC_PLATFORM enabled by default.
I've just noticed that this can actually help on
some configurations that don't enable any STMMAC
options by default (e.g. SPEAr).

snmp: fix OutOctets counter to include forwarded datagrams
RFC 4293 defines ipIfStatsOutOctets (similar definition for
ipSystemStatsOutOctets):
The total number of octets in IP datagrams delivered to the lower

ipIfStatsOutTransmits MUST be counted here.
And ipIfStatsOutTransmits:
The total number of IP datagrams that this entity supplied to the
lower layers for transmission. This includes datagrams generated
locally and those forwarded by this entity.
Therefore, IPSTATS_MIB_OUTOCTETS must be incremented when incrementing
IPSTATS_MIB_OUTFORWDATAGRAMS.
IP_UPD_PO_STATS is not used since ipIfStatsOutRequests must not
include forwarded datagrams:

that this counter does not include any datagrams counted in
