Preparation for disconnecting the nf_conntrack_lock from the
expectations code. Once the nf_conntrack_lock is lifted, a race
condition is exposed.
The expectations master conntrack exp->master, can race with
delete operations, as the refcnt increment happens too late in
init_conntrack(). Race is against other CPUs invoking
->destroy() (destroy_conntrack()), or nf_ct_delete() (via timeout
or early_drop()).
Avoid this race in nf_ct_find_expectation() by using atomic_inc_not_zero(),
and checking if nf_ct_is_dying() (path via nf_ct_delete()).

Adds a new property for hash set types, where if a set is created
with the 'forceadd' option and the set becomes full the next addition
to the set may succeed and evict a random entry from the set.
To keep overhead low eviction is done very simply. It checks to see
which bucket the new entry would be added. If the bucket's pos value
is non-zero (meaning there's at least one entry in the bucket) it
replaces the first entry in the bucket. If pos is zero, then it continues
down the normal add process.
This property is useful if you have a set for 'ban' lists where it may
not matter if you release some entries from the set early.

commit 2dfb973c0dcc6d2211 (add markmask for hash:ip,mark data type)
inserted IPSET_ATTR_MARKMASK in-between other enum values, i.e.
changing values of all further attributes. This causes 'ipset list'
segfault on existing kernels since ipset no longer finds
IPSET_ATTR_MEMSIZE (it has a different value on kernel side).
Jozsef points out it should be moved below IPSET_ATTR_MARK which
works since there is some extra reserved space after that value.

Introduce packet mark support with new ip,mark hash set. This includes
userspace and kernelspace code, hash:ip,mark set tests and man page
updates.
The intended use of ip,mark set is similar to the ip:port type, but for
protocols which don't use a predictable port number. Instead of port
number it matches a firewall mark determined by a layer 7 filtering
program like opendpi.
As well as allowing or blocking traffic it will also be used for
accounting packets and bytes sent for each protocol.

ipset(8) for list:set says:
The match will try to find a matching entry in the sets and the
target will try to add an entry to the first set to which it can
be added.
However real behavior is bit differ from described. Consider example:
# ipset create test-1-v4 hash:ip family inet
# ipset create test-1-v6 hash:ip family inet6
# ipset create test-1 list:set
# ipset add test-1 test-1-v4
# ipset add test-1 test-1-v6
# iptables -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src
# ip6tables -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src
And then when iptables/ip6tables rule matches packet IPSET target
tries to add src from packet to the list:set test-1 where first
entry is test-1-v4 and the second one is test-1-v6.
For IPv4, as it first entry in test-1 src added to test-1-v4
correctly, but for IPv6 src not added!
Placing test-1-v6 to the first element of list:set makes behavior
correct for IPv6, but brokes for IPv4.
This is due to result, returned from ip_set_add() and ip_set_del() from
net/netfilter/ipset/ip_set_core.c when set in list:set equires more
parameters than given or address families do not match (which is this
case).
It seems wrong returning 0 from ip_set_add() and ip_set_del() in
this case, as 0 should be returned only when an element successfuly
added/deleted to/from the set, contrary to ip_set_test() which
returns 0 when no entry exists and >0 when entry found in set.

The of_mdiobus_register_phy() is not setting phy->irq thus causing
some drivers to incorrectly assume that the PHY does not have an
IRQ associated with it. Not only do some drivers report no IRQ
they do not install an interrupt handler for the PHY.
Simplify the code setting irq and set the phy->irq at the same
time so that we cover the following issues, which should cover
all the cases the code will find:
- Set phy->irq if node has irq property and mdio->irq is NULL
- Set phy->irq if node has no irq and mdio->irq is not NULL
- Leave phy->irq as PHY_POLL default if none of the above
This fixes the issue:

This patch is an attempt to gather the Ethernet related bindings in one file,
like it's done in the MMC and some other subsystems. It should save some of
the trouble of documenting several properties over and over in each binding
document, instead only making reference to the main file.
I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR)
standard as a base for the properties description, also documenting some ad-hoc
properties that have been introduced over time despite having direct analogs in
ePAPR.

====================
Please pull this batch of fixes intended for the 3.14 stream...
For the iwlwifi one, Emmanuel says:
"As explicitly written in the commit message, we prefer to disable Tx
AMPDU on NICs supported by iwldvm. This feature gives a big boost in
Tx performance, but the firmware is buggy and we can't rely on it.
Our hope is that most of the users out there want wifi to surf on
the web which means that they care more for Rx traffic than for Tx.
People who want to enable it can do so with the help of a module
parameter."
On top of that...
Dan Carpenter fixes a typo/thinko in ath5k.
Olivier Langlois fixes a couple of rtlwifi issues, one which leaves
IRQs disabled too long (causing a variety of problems elsewhere),
and one which fixes an incorrect return code when failing to enable
the NIC.
Russell King fixes a NULL pointer dereference in hostap.
Stanislaw Gruszka fixes a DMA coherence issue in the rtl8187 driver.
Please let me know if there are problems!

bonding: add an option to rely on unvalidated arp packets
v4 -> v5:
Again per Nik's advise correct the bond_opts restrictions for arp_validate
- set it the same as arp_interval.
v3 -> v4:
Per Nikolay's advise, remove the new bond_opts restriction on modes setting
for arp_validate.
v2 -> v3:
Per Jay's advise, use the 'filter' keyword instead of 'arp' one, and use
his text for documentation. Also, rebase on the latest net-next. Sorry for
the delay, didn't manage to send it before net-next was closed.
v1 -> v2:
Don't remove the 'all traffic' functionality - rather, add new arp_validate
options to specify that we want *only* unvalidated arps.
Currently, if arp_validate is off (0), slave_last_rx() returns the
slave->dev->last_rx, which is always updated on *any* packet received by
slave, and not only arps. This means that, if the validation of arps is
off, we're treating *any* incoming packet as a proof of slave being up, and
not only arps.
This might seem logical at the first glance, however it can cause a lot of
troubles and false-positives, one example would be:
The arp_ip_target is NOT accessible, however someone in the broadcast domain
spams with any broadcast traffic. This way bonding will be tricked that the
slave is still up (as in - can access arp_ip_target), while it's not.
The net_device->last_rx is already used in a lot of drivers (even though the
comment states to NOT do it :)), and it's also ugly to modify it from bonding.
However, some loadbalance setups might rely on the fact that even non-arp
traffic is a sign of slave being up - and we definitely can't break anyones
config - so an extension to arp_validate is needed.
So, to fix this, add an option for the user to specify if he wants to
filter out non-arp traffic on unvalidated slaves, remove the last_rx from
bonding, *always* call bond_arp_rcv() in slave's rx_handler (which is
bond_handle_frame), and if we spot an arp there with this option on - update
the slave->last_arp_rx - and use it instead of net_device->last_rx. Finally,
rename last_arp_rx to last_rx to reflect the changes.
Also rename slave->jiffies to ->last_link_up, to reflect better its
meaning, add the new option's documentation and update the arp_validate one
to be a bit more descriptive.

slave->jiffies is updated every time the slave becomes active, which, for
bonding, means that its link is 'up'.
