Every action ops has a pointer to hash info, so we don't need to
hard-code it in each module.

When I create a new namespace with 'ip netns add net0', or add/remove
new links in a namespace with 'ip link add/delete type veth', rx/tx
queues events can be got in all namespaces. That is because rx/tx queue
ktypes do not have namespace support, and their kobj parents are setted to
NULL. This patch is to fix it.

ipv6_link_dev_addr sorts newly added addresses by scope in
ifp->addr_list. Smaller scope addresses are added to the tail of the
list. Use this fact to iterate in reverse over addr_list and break out
as soon as a higher scoped one showes up, so we can spare some cycles
on machines with lot's of addresses.
The ordering of the addresses is not relevant and we are more likely to
get the eui64 generated address with this change anyway.

We currently don't report IPV6_RECVPKTINFO in cmsg access ancillary data
for IPv4 datagrams on IPv6 sockets.
This patch splits the ip6_datagram_recv_ctl into two functions, one
which handles both protocol families, AF_INET and AF_INET6, while the
ip6_datagram_recv_specific_ctl only handles IPv6 cmsg data.
ip6_datagram_recv_*_ctl never reported back any errors, so we can make
them return void. Also provide a helper for protocols which don't offer dual
personality to further use ip6_datagram_recv_ctl, which is exported to
modules.
I needed to shuffle the code for ping around a bit to make it easier to
implement dual personality for ping ipv6 sockets in future.

For user space packet capturing libraries such as libpcap, there's
currently only one way to check which BPF extensions are supported
by the kernel, that is, commit aa1113d9f85d ("net: filter: return
-EINVAL if BPF_S_ANC* operation is not supported"). For querying all
extensions at once this might be rather inconvenient.
Therefore, this patch introduces a new option which can be used as
an argument for getsockopt(), and allows one to obtain information
about which BPF extensions are supported by the current kernel.
As David Miller suggests, we do not need to define any bits right
now and status quo can just return 0 in order to state that this
versions supports SKF_AD_PROTOCOL up to SKF_AD_PAY_OFFSET. Later
additions to BPF extensions need to add their bits to the
bpf_tell_extensions() function, as documented in the comment.

Fix this by holding a reference only if dst really cached.
2) Remove a lockdep warning in __tunnel_dst_set()
This was reported by Cong Wang.
3) Remove usage of a spinlock where xchg() is enough
4) Remove some spurious inline keywords.

The RFC 3810 defines two type of messages for multicast
listeners. The "Current State Report" message, as the name
implies, refreshes the *current* state to the querier.
Since the querier sends Query messages periodically, there
is no need to retransmit the report.
On the other hand, any change should be reported immediately
using "State Change Report" messages. Since it's an event
triggered by a change and that it can be affected by packet
loss, the rfc states it should be retransmitted [RobVar] times
to make sure routers will receive timely.
Currently, we are sending "Current State Reports" after
DAD is completed. Before that, we send messages using
unspecified address (::) which should be silently discarded
by routers.
This patch changes to send "State Change Report" messages
after DAD is completed fixing the behavior to be RFC compliant
and also to pass TAHI IPv6 testsuite.

The REGULATORY_CUSTOM_REG can be used during early init with
the goal of overriding the wiphy's default regulatory settings
in case the alpha2 of the device is not known. In the case that
the alpha2 becomes known lets avoid having drivers having to
clear the REGULATORY_CUSTOM_REG flag by doing it for them
when regulatory_hint() is used.

If a uAPSD service period ends with an MMPDU, we currently just
send that MMPDU, but it obviously won't get the EOSP bit set as
it doesn't have a QoS header. This contradicts the standard, so
add a QoS-nulldata frame after the MMPDU to properly terminate
the service period with a frame that has EOSP set.
Also fix a bug wrt. the TID for the MMPDU, it shouldn't be set
to 0 unconditionally but use the actual TID that was assigned.

The temporary TX info flags need to be cleared if the frame will
be processed through the TX handlers again, otherwise it can get
messed up. This fixes a bug that happened when an aggregation
session was stopped while the station was sleeping - some frames
might get transmitted marked as aggregation erroneously without
this fix.

When a response for PS-Poll or a uAPSD trigger frame is sent, the
more-data bit should be set according to 802.11-2012 11.2.1.5 h),
meaning that it should indicate more data on the relevant ACs
(delivery-enabled or nondelivery-enabled for uAPSD or PS-Poll.)
In, for example, the following scenario:
* 1 frame on VO queue (either in driver or in mac80211)
* at least 1 frame on VI queue (in the driver)
* both VO/VI are delivery-enabled
* uAPSD trigger frame received
The more-data flag to the driver would not be set, even though
it should be.
While fixing this, I noticed that we should really release frames
from multiple ACs where there's data buffered in the driver for
the corresponding TIDs.
To address all this, restructure the code a bit to consider all
ACs if we only release driver frames or only buffered frames.
This also addresses the more-data bug described above as now the
TIDs will all be marked as released, so the driver will have to
check the number of frames.
While at it, clarify some code and comments and remove the found
variable, replacing it with the appropriate sw/hw release check.

Using ffs() for the PS-Poll release TID is wrong, it will cause
frames to be released in order 0 1 2 3 4 5 6 7 instead of the
correct 7 6 5 4 3 0 2 1. Fix this by adding a new function that
implements "highest priority TID" properly.

In managed mode, we should not ask for OFF mode because the
power settings may still require DYNAMIC. In AP mode, this
should be allowed since the default settings is OFF and
AUTOMATIC is not allowed.

While getting the retry limit, wext-compat returns the value
without updating the flag for retry->flags is 0. Also in this
case, it updates long retry flag when short and long retry
value are unequal.
So, iwconfig never showing "Retry short limit" and showing
"Retry long limit" when both values are unequal.
Updated the flags and corrected the condition properly.

Samuel Ortiz <sameo@linux.intel.com> says:
"This is the first NFC pull request for 3.14
It includes:
* A new NFC driver for Marvell's 8897, and a few NCI fixes and
improvements needed to support this chipset.
* An LLCP fix for how we were setting the default MIU on a p2p link. If
there is no explicit MIU extension announced at connection time, we
must use the default one and not the one announced at LLCP link
establishement time.
* A pn544 EEPROM config update. Some of the currently EEPROM configured
values are overwriting the firmware ones while other should not be set
by the driver itself.
* Some NFC digital stack fixes and improvements. Asynchronous functions
are better documented, RF technologies and CRC functions are set upon
PSL_REQ reception, and a few minor bugs are fixed.
* Minor and miscelaneous pn533, mei_phy and port100 fixes."

The curr_protocol field of nfc_digital_dev structure used to determine
if a target is currently active was set too soon, immediately when a
target is found. This is not good since there is no other way than
deactivate_target() to reset curr_protocol and if activate_target() is
not called, the target remains active and it's not possible to put the
device in poll mode anymore.
With this patch curr_protocol is set when nfc core activates a target,
puts a device up, or when an ATR_REQ is received in target mode.

nci_close_device() sends nci reset command to the device.
If there is no response for this command, nci request timeout
occurs first and then cmd timeout happens. Because command
timer has started after sending the command.
We are immediately flushing command workqueue after nci
timeout. Later we will try to schedule cmd_work in command
timer which leads to a crash.
Cancel cmd_timer before flushing the workqueue to fix the
problem.
