Hook a ndo_set_mac_address callback, update the internal Ethernet MAC in
the netdevice structure, and finally write that address down to the
UniMAC registers. If the interface is down, and most likely clock gated,
we do not update the registers but just the local copy, such that next
ndo_open() call will effectively write down the address.

pull request: wireless-next 2014-12-08
Please pull this last batch of pending wireless updates for the 3.19 tree...
For the wireless bits, Johannes says:
"This time I have Felix's no-status rate control work, which will allow
drivers to work better with rate control even if they don't have perfect
status reporting. In addition to this, a small hwsim fix from Patrik,
one of the regulatory patches from Arik, and a number of cleanups and
fixes I did myself.
Of note is a patch where I disable CFG80211_WEXT so that compatibility
is no longer selectable - this is intended as a wake-up call for anyone
who's still using it, and is still easily worked around (it's a one-line
patch) before we fully remove the code as well in the future."
For the Bluetooth bits, Johan says:
"Here's one more bluetooth-next pull request for 3.19:
- Minor cleanups for ieee802154 & mac802154
- Fix for the kernel warning with !TASK_RUNNING reported by Kirill A.
Shutemov
- Support for another ath3k device
- Fix for tracking link key based security level
- Device tree bindings for btmrvl + a state update fix
- Fix for wrong ACL flags on LE links"
And...
"In addition to the previous one this contains two more cleanups to
mac802154 as well as support for some new HCI features from the
Bluetooth 4.2 specification.
From the original request:
'Here's what should be the last bluetooth-next pull request for 3.19.
It's rather large but the majority of it is the Low Energy Secure
Connections feature that's part of the Bluetooth 4.2 specification. The
specification went public only this week so we couldn't publish the
corresponding code before that. The code itself can nevertheless be
considered fairly mature as it's been in development for over 6 months
and gone through several interoperability test events.
Besides LE SC the pull request contains an important fix for command
complete events for mgmt sockets which also fixes some leaks of hci_conn
objects when powering off or unplugging Bluetooth adapters.
A smaller feature that's part of the pull request is service discovery
support. This is like normal device discovery except that devices not
matching specific UUIDs or strong enough RSSI are filtered out.
Other changes that the pull request contains are firmware dump support
to the btmrvl driver, firmware download support for Broadcom BCM20702A0
variants, as well as some coding style cleanups in 6lowpan &
ieee802154/mac802154 code.'"
For the NFC bits, Samuel says:
"With this one we get:
- NFC digital improvements for DEP support: Chaining, NACK and ATN
support added.
- NCI improvements: Support for p2p target, SE IO operand addition,
SE operands extensions to support proprietary implementations, and
a few fixes.
- NFC HCI improvements: OPEN_PIPE and NOTIFY_ALL_CLEARED support,
and SE IO operand addition.
- A bunch of minor improvements and fixes for STMicro st21nfcb and
st21nfca"
For the iwlwifi bits, Emmanuel says:
"Major works are CSA and TDLS. On top of that I have a new
firmware API for scan and a few rate control improvements.
Johannes find a few tricks to improve our CPU utilization
and adds support for a new spin of 7265 called 7265D.
Along with this a few random things that don't stand out."
And...
"I deprecate here -8.ucode since -9 has been published long ago.
Along with that I have a new activity, we have now better
a infrastructure for firmware debugging. This will allow to
have configurable probes insides the firmware.
Luca continues his work on NetDetect, this feature is now
complete. All the rest is minor fixes here and there."
For the Atheros bits, Kalle says:
"Only ath10k changes this time and no major changes. Most visible are:
o new debugfs interface for runtime firmware debugging (Yanbo)
o fix shared WEP (Sujith)
o don't rebuild whenever kernel version changes (Johannes)
o lots of refactoring to make it easier to add new hw support (Michal)
There's also smaller fixes and improvements with no point of listing
here."
In addition, there are a few last minute updates to ath5k,
ath9k, brcmfmac, brcmsmac, mwifiex, rt2x00, rtlwifi, and wil6210.
Also included is a pull of the wireless tree to pick-up the fixes
originally included in "pull request: wireless 2014-12-03"...
Please let me know if there are problems!

Intel Wired LAN Driver Updates 2014-12-09
This series contains updates to i40e and i40evf.
Jeff (me) provides a single patch to convert a macro to a static inline
function based on feedback from Joe Perches on a previous patch.
Shannon provides the remaining twelve patches against i40e. Almost all
of Shannon's patches cleanup/fix NVM issues varying in range from
adding more detail to debug messages, to removing dead code, to fixing
NVM state transitions after an error. Change the handy decoder interface
for admin queue return code to help catch and properly report the condition
as a useful errno rather than returning a misleading '0'. Added a range
check to avoid any possible array index-out-of-bound issues.
v2:
- fixed up patch 05 in the series to use the ARRAY_SIZE() macro as suggested
by Sergei Shtylyov
- fix up patch 13 to remove unnecessary parens in the return statement
as suggested by Sergei Shtylyov

Rework the debug messages in the NVM update state machine so that we can
turn them on and off dynamically rather than forcing a recompile/reload.
These can now be turned on with something like:
ethtool -s eth1 msglvl 0xf000008f
and off with:
ethtool -s eth1 msglvl 0xf000000f
The high 0xf0000000 gets the driver's attention that we want to change the
internal debug flags, and the 0x80 bit is the NVM debug.

The NVM update operations take time finish asynchronously, and follow-on
update requests need to wait for the current one to finish. Early
firmware didn't handle this well, so the code had to track the busy state.
The released firmware handles the busy state correctly, returning
I40E_AQ_RC_EBUSY if an update is still in progress, so the code no longer
needs to track this.

Our FW can support several fastpath HSI [for backward compatibility] but up
until now VFs were always configured to use latest fastpath HSI [although VF
driver might be older and use an older fastpath HSI].
For linux drivers, the differences are insignificant since driver never
utilized features that were overridden by the HSI change. But for VMs running
other operating systems this might be a problem.
In addition, eventually FW might change fastpath HSI in such a manner that
backward compatibility WILL break unless configured with proper version.
This patch fixes the issue for other operating system VMs, as well as lays
the ground work for forward compatibility in regard to the fastpath HSI.

The comment says that the built-in strncmp didn't work. That is not
surprising, as apparently "str" semantics are not really what is
wanted (hint: de4x5_strncmp only stops when two different bytes are
encountered or the end is reached; not if either byte happens to be
0). de4x5_strncmp is actually a memcmp (except for the signature and
that bytes are not necessarily treated as unsigned char); since only
the boolean value of the result is used we can just replace
de4x5_strncmp with memcmp.

It modifies drivers implementation of set/get_rxfh accordingly.
This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.
User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.
Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

====================
Intel Wired LAN Driver Updates 2014-12-06
This series contains updates to i40e and i40evf.
Shannon provides several patches to cleanup and fix i40e. First removes
an unneeded break statement in i40e_vsi_link_event(). Then removes
some debug messages that really do not give any useful information and
ends up getting printed every service_task loop, which fills the logfile
with noise when AQ tracing is enabled. Updates the aq_cmd arguments to
use %i which is much more forgiving and user friendly than the more
restrictive %x, or %d. Fixes the netdev_stat macro, where the old
xxx_NETDEV_STAT() macro was defined long before the newer
rtnl_link_stats64 came into being, and just never got updated.
Getting the pf_id from the function number had an issue when
when the PF was setup in passthru mode, the PCI bus/device/function
was virtualized and the number in the VM is different from the number in
the bare metal. This caused HW configuration issues when the wrong pf_id
was used to set up the HMC and other structures. The PF_FUNC_RID register
has the real bus/device/function information as configured by the BIOS,
so use that for a better number.
Carolyn adds additional text description for the base pf0 and flow
director generated interrupts, since these interrupts are difficult
to distinguish per port on a multi-function device.
Jacob resolves an issue related to images with multiple PFs per
physical port. We cannot fully support 1588 PTP features, since only
one port should control (i.e. write) the registers at a time. Doing
so can cause interference of functionality.
Anjali provides several updates to i40e, first adds the Virtual Channel
OP event opcode for CONFIG_RSS, so that the Virtual Channel state
machine can properly decipher status change events. Then updates the
driver to add (and use) i40e_is_vf macro for future expansion when new
VF MAC types get added. Adds new update VSI flow to accommodate a
firmware dix with VSI loopback mode. All VSIs on a VEB should either
have loopback enabled or disabled, a mixed mode is not supported for a
VEB. Since our driver supports multiple VSIs per PF that need to talk to
each other make sure to enable Loopback for the PF and FDIR VSI as well.
Mitch provides a couple of i40e and i40evf patches. First updates
i40evf init code more adept at handling when multiple VFs attempt
to initialize simultaneously.
Joe Perches provides a i40e patch which resolves a compile warning
about about frame size being larger than 2048 bytes by reducing the
stack use by using kmemdup and not using a very large struct on the
stack.
v2:
- Dropped patch 13 & 14 while Mitch reworks the patches based on
feedback from Ben Hutchings, probably the tryptophan in the turkey
is to blame for the delay...
- Added Joe Perches patch which resolves a compile warning about frame
size

Replace rtl_skb_pad with eth_skb_pad since they do the same thing.

Update myri10ge to use eth_skb_pad helper. This also corrects a minor
issue as the driver was updating length without updating the tail pointer.
