John W. Linville says:
====================
Please pull this batch of updates for the 3.14 stream...
For the Bluetooth bits, Gustavo says:
"This is the first batch of patches intended for 3.14. There is
nothing big here. Most of the code are refactors, clean up, small
fixes, plus some new device id support."
And...
"More patches to 3.14. Here we have the support for Low Energy
Connection Oriented Channels (LE CoC). Basically, as the name says,
this adds supports for connection oriented channels in the same way
we already have them for BR/EDR connections so profiles/protocols
that work on top of BR/EDR can now work on LE plus a plenty of new
possibilities for LE."
For the ath10k bits, Kalle says:
"Janusz and Marek implemented DFS support to ath10k, but the code is
not enabled yet due to missing cfg80211/mac80211 patches (it will be
enabled in the next pull request). Michal did some device reset fixes
and made it possible for ath10k to share an interrupt with another
device. And lots of smaller fixes from different people."
For the iwlwifi bits, Emmanuel says:
"I have here a big rework of the rate control by Eyal. This is obviously
the biggest part of this batch.
I also have enhancement of protection flags by Avri and a few bits for
WoWLAN by Eliad and Luca. Johannes cleans up the debugfs plus a few
fixes. I provided a few things for Bluetooth coexistence.
Besides this we have an implementation for low priority scan."
Along with all that, there are big batches of updates to mwifiex and
ath9k, Jeff Kirsher's FSF address fix patches, and a handful of other
bits here and there.
Please let me know if there are problems!

When phydev is going to HALTED state, we can try to suspend it to
safe more power. phy_suspend helper will check if PHY can be suspended,
so just call it when entering HALTED state.

====================
Intel Wired LAN Driver Updates
This series contains updates to i40e only (again).
Jesse provides a fix for when tx_rings structure is NULL and we do not want
to panic. Then refactors the flow control set up and disables L2 flow control
by default. Provides some trivial fixes as well as prevent compiler warnings.
Then to align to similar behaviour in ixgbe, use the total number of CPUs in
the system to suggest the number of transmit and receive queue pairs.
Shannon provides a i40e ethtool fix to get some more reasonable information
reports back out to the ethtool. In addition, fixes PF reset after offline
test, where it reorders the test to put the register test last as it is the
only one that needs a reset, and we wait to trigger the reset until after we
clear the testing bit. Lastly provides basic support for handling suspend
and resume for now, later on Wake-On-LAN support will be added.
Anjali provides changes to tell the stack about our actual number of queues
in order for RFS/RPS/XFS to work correctly. Then provides several patches to
implement dynamically changing the queue count for the main VSI. Adds
basic support for get/set channels for RSS so that the number of receive and
transmit queue pair can be changed via ethtool. Cleans up the use of
rtnl_lock in the reset patch since it runs from a work time.
Neerav Parikh cleans up the VF interface to remove FCoE code as this
feature will not be supported on VF interfaces.
v2:
- submitted patch 1 to net (since it was a fix needed for net), so dropped
from this series (this patch will get added to net-next when Dave syncs
his trees)
- Dropped patches 4 & 11 from previous submission because of feedback
received from Ben Hutchings and Sergei Shtylyov.

Any user-initiated path which eventually calls reset needs
to hold the rtnl_lock, so add functionality to do that.
Be careful not to use the safe reset when cleaning up
from the diagnostic tests, which avoids rtnl_lock
recursion from ethtool.
Protect the reset_task with rtnl_lock, since it runs from a work item.

to be able to change just the queue count and not the number of

The current driver default sets the number of transmit/receive
queue pairs based on the current node's CPU count.
A better method is to use the total number of CPUs in the system
to suggest the number of queue pairs, which aligns better with
the behavior of ixgbe, and also with the expectations of the
kernel XPS and other subsystems in the stack.

When the ethtool testing starts it sets the I40E_TESTING state
bit, which blocks new netdev opens so that things don't get
confused, while the testing might be messing with register and
other things. Unfortunately, that was keeping the PF resets
after the register test from working correctly because the netdev
would not get reopened. This patch reorders the tests to put the
register test last as it is the only one that needs a reset, and
we wait to trigger the reset until after we clear the
I40E_TESTING bit.

The bond_resend_igmp_join_requests_delayed() and
bond_resend_igmp_join_requests() should be integrated,
because the bond_resend_igmp_join_requests_delayed() did
nothing except bond_resend_igmp_join_requests().
The bond igmp_retrans could only be changed in bond_change_active_slave
and here, bond_change_active_slave will be called in RTNL and curr_slave_lock,
the bond_resend_igmp_join_requests already hold RTNL, so no need
to free RTNL and hold curr_slave_lock again, it may be a small optimization,
so move the igmp_retrans in RTNL and remove the curr_slave_lock.

The bond_3ad_state_machine_handler() use the bond lock to protect
the bond slave list and slave port together, but it is not enough,
the bond slave list was link and unlink in RTNL, not bond lock,
so I add RCU to protect the slave list from leaving.
The bond lock is still used here, because when the slave has been
removed from the list by the time the state machine runs, it appears
to be possible for both function to manupulate the same aggregator->lag_ports
by finding the aggregator via two different ports that are both members of
that aggregator (i.e., port A of the agg is being unbound, and port B
of the agg is runing its state machine).
If I remove the bond lock, there are nothing to mutex changes
to aggregator->lag_ports between bond_3ad_state_machine_handler and
bond_3ad_unbind_slave, So the bond lock is the simplest way to protect
aggregator->lag_ports.
There was a lot of function need RCU protect, I have two choice
to make the function in RCU-safe, (1) create new similar functions
and make the bond slave list in RCU. (2) modify the existed functions
and make them in read-side critical section, because the RCU
read-side critical sections may be nested.
I choose (2) because it is no need to create more similar functions.
The nots in the function is still too old, clean up the nots.

The bond_change_active_slave() and bond_select_active_slave()
do't need bond lock anymore, so remove the unwanted bond lock
for these two functions.
The bond_select_active_slave() will release and acquire
curr_slave_lock, so the curr_slave_lock need to protect
the function.
In bond enslave and bond release, the bond slave list is also
protected by RTNL, so bond lock is no need to exist, remove
the lock and clean the functions.

The bond_activebackup_arp_mon() use the bond lock for read to
protect the slave list, it is no effect, and the RTNL is only
called for bond_ab_arp_commit() and peer notify, for the performance
better, use RCU to replace with the bond lock, to the bond slave
list need to called in RCU, add a new bond_first_slave_rcu()
to get the first slave in RCU protection.
In bond_ab_arp_probe(), the bond->current_arp_slave may changd
if bond release slave, just like:
bond_ab_arp_probe() bond_release()
cpu 0 cpu 1
...
if (bond->current_arp_slave...) ...
... bond->current_arp_slave = NULl
bond->current_arp_slave->dev->name ...
So the current_arp_slave need to dereference in the section.

The bond_mii_monitor() still use bond lock to protect bond slave list,
it is no effect, I have 2 way to fix the problem, move the RTNL to the
top of the function, or add RCU to protect the bond slave list,
according to the Jay Vosburgh's opinion, 10 times one second is a
truely big performance loss if use RTNL to protect the whole monitor,
so I would take the advice and use RCU to protect the bond slave list.
The bond_has_slave() will not protect by anything, there will no things
happen if the slave list is be changed, unless the bond was free, but
it will not happened before the monitor, the bond will closed before
be freed.
The peers notify for the bond will calling curr_active_slave, so
derefence the slave to make sure we will accessing the same slave
if the curr_active_slave changed, as the rcu dereference need in
read-side critical sector and bond_change_active_slave() will call
it with no RCU hold, so add peer notify in rcu_read_lock which
will be nested in monitor.

The bond slave list was no longer protected by bond lock and only
protected by RTNL or RCU, so anywhere that use bond lock to protect
slave list is meaningless.
remove the release and acquire bond lock for bond_select_active_slave().
The curr_active_slave could only be changed in 3 place:
1. enslave slave.
2. release slave.
3. change_active_slave.
all above place were holding bond lock, RTNL and curr_slave_lock
together, it is tedious and meaningless, obviously bond lock is no
need here, but RTNL or curr_slave_lock is needed, so if you want
to access active slave, you have to choose one lock, RTNL or
curr_slave_lock, if RTNL is exist, no need to add curr_slave_lock,
otherwise curr_slave_lock is better, because of the performance.
there are several place calling bond_select_active_slave() and
bond_change_active_slave(), the next step I will clean these place
and remove the no effect lock.
there are some document changed together when update the function.

The SFC9100 family has only one clock per controller, shared by all
functions. Therefore only create a clock device under the primary
function, and make all other functions refer to the primary's clock
device.
Since PTP functionality is limited to port 0 and PF 0 on the earlier
SFN[56]322F boards, and we also set the primary flag for that
function, we can make the creation of a clock device conditional only
on this flag.

The primary function of an EF10 controller will share its clock
device with other functions in the same domain (which we call
secondary functions). To this end, we need to associate functions
on the same controller.
We do not control probe order, so allow primary and secondary
functions to appear in any order. Maintain global lists of all
primary functions and of unassociated secondary functions,
and a list of secondary functions on each primary function.
Use the VPD serial number to tell whether functions are part of the
same controller. VPD will not be readable by virtual functions, so
this may need to be revisited later.
