0d40b6101f amd-xgbe-phy: Use the proper auto-negotiation XNP registers
When receiving and processing extended next pages the base registers
were used instead of the XNP registers. Update the code to use the
device XNP and link partner XNP registers.

c3152d4728 amd-xgbe-phy: Change auto-negotiation logic
The auto negotiation logic was geared to being the initiator of the
auto negotiation. This presented problems when auto negotiation was
initiated by the remote end. Change the auto negotiation logic to
make use of the auto negotiation event interrupt thus allowing the
auto negotiation state machine to function properly in either scenario.
This also removes the polling during auto-negotiation.

a83ef427b7 amd-xgbe: Remove need for Tx path spinlock
Since the Tx ring cleanup can run at the same time that data is being
transmitted, a spin lock was used to protect the ring. This patch
eliminates the need for Tx spinlocks by updating the current ring
position only after all ownership bits for data being transmitted have
been set. This will insure that ring operations in the Tx cleanup path
do not interfere with the ring operations in the Tx transmit path.

916102c666 amd-xgbe: Clear all state during a device restart
When performing a device restart, like during an MTU change, sometimes

63d7e5a413 i40e: Support for NPAR iSCSI partition with DCB
Add parsing and reporting of iSCSI capability for a given device or
function.

Also add support for iSCSI partition type with DCB in NPAR mode.
In this mode it is expected that software would configure both the LAN
and iSCSI traffic classes for the iSCSI partition; whereas all the NIC
type partitions will use LAN TC (TC0) only.
Hence, the patch enables querying of DCB configuration in MFP mode and
configures TCs for iSCSI partition type.

Though NIC type partitions may not have more than 1 TC enabled for them
the port may have multiple TCs enabled and hence I40E_FLAG_DCB_ENABLED
will be set/reset on all the partitions based on number of TCs on the
port. This is required as in DCB environment it is expected that all
traffic will be priority tagged.

4fda14ca0f i40e: when Rx timestamps disabled set specific mode
Instead of leaving the Rx timestamps in the same mode as before if we
disable the Rx logic, we can set it into a mode that has the fewest
possible timestamps generated. To do this, select only V1 mode, but do
not enable UDP packet recognition. This should eliminate all (or at
least almost all) Rx timestamps, since V1 packets are always over UDP.

b535a01319 i40e: use same check for Rx hang as for Rx timestamps
It's possible that the user configured only Tx hardware timestamping,
and thus we might be receiving PTP traffic which we timestamp but which
software never reads. In this case we don't want to check for Rx
timestamp hang, because we already know that software won't be handling
them. Thus, we add the same check against pf->ptp_rx as we have in the
Rx timestamp code path.

57699a40b4 rhashtable: Fix race in rhashtable_destroy() and use regular work_struct
When we put our declared work task in the global workqueue with
schedule_delayed_work(), its delay parameter is always zero.
Therefore, we should define a regular work in rhashtable structure
instead of a delayed work.

By the way, we add a condition to check whether resizing functions
are NULL before cancelling the work, avoiding to cancel an
uninitialized work.

Lastly, while we wait for all work items we submitted before to run
to completion with cancel_delayed_work(), ht->mutex has been taken in
rhashtable_destroy(). Moreover, cancel_delayed_work() doesn't return
until all work items are accomplished, and when work items are
scheduled, the work's function - rht_deferred_worker() will be called.
However, as rht_deferred_worker() also needs to acquire the lock,
deadlock might happen at the moment as the lock is already held before.
So if the cancel work function is moved out of the lock covered scope,
this will avoid the deadlock.

  * a change to drop packets while disconnecting from
    an AP instead of trying to wait for them
  * a new attempt at improving the tailroom accounting
    to not kick in too much for performance reasons
  * improvements in wireless link statistics
  * many other small improvements and small fixes that
    didn't seem necessary for 3.19 (e.g. in hwsim which
    is testing only code)

Merge tag 'mac80211-next-for-davem-2015-01-15' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Here's a big pile of changes for this round.

We have
 * a lot of regulatory code changes to deal with the
   way newer Intel devices handle this
 * a change to drop packets while disconnecting from
   an AP instead of trying to wait for them
 * a new attempt at improving the tailroom accounting
   to not kick in too much for performance reasons
 * improvements in wireless link statistics
 * many other small improvements and small fixes that
   didn't seem necessary for 3.19 (e.g. in hwsim which
   is testing only code)

Conflicts:

Get a reference on every ipv6 address we offload to hardware so that it cannot
be prematurely cleared out before cleanup.

b5a02f503c cxgb4 : Update ipv6 address handling api
This patch improves on previously added support for ipv6 addresses. The code
is consolidated to a single file and adds an api for use by dependent upper
level drivers such as cxgb4i/iw_cxgb4 etc.

5055c371bf ipv4: per cpu uncached list
RAW sockets with hdrinc suffer from contention on rt_uncached_lock
spinlock.

One solution is to use percpu lists, since most routes are destroyed
by the cpu that created them.

It is unclear why we even have to put these routes in uncached_list,
as all outgoing packets should be freed when a device is dismantled.

2b8df32395 Bluetooth: Add paranoid check for existing LE and BR/EDR SMP channels
When the SMP channels have been already registered, then print out a
clear WARN_ON message that something went wrong. Also unregister the
existing channels in this case before trying to register new ones.

0799c2d6f4 net: sh_eth: Use u32 for 32-bit register data
Replace "unsigned long" by "u32" when handling 32-bit register data.

A.o., this saves 11 * 36 bytes in the static sh_eth_cpu_data structures
when compiling for 64-bit.

7994fe55a4 dm9000: Add regulator and reset support to dm9000
In boards, the dm9000 chip's power and reset can be controlled by gpio.

It makes sense to add them to the dm9000 driver and let dt be used to
enable power and reset the phy.
