Intel Wired LAN Driver Updates 2015-02-09
This series contains updates to i40e and i40evf only.
Rickard Strandqvist removes an unused function for i40e.
John Linville reorders a piece of code so that y_budget does not get used
by the FCoE code before it gets initialized.
Mitch adds a delay after VF reset with a minimum of 10ms to allow the
hardware internal FIFOs to flush. Bumps up the ARQ descriptors, since
we can easily overrun the PF's admin receive queue. Added locking around
the VF reset code, since during VF deallocation, we cannot depend on
simply masking the interrupt since this does not lock out the service task,
which can still call the reset routine. Fix a potential multi-minute
delay on driver unload, VF disable or system shutdown. When the module
is being unloaded, waiting for the PF to politely handle all of our admin
queue requests might take forever with a lot of VFs enabled, so just
stop everything and request a VF reset. Also stops the watchdog during
shutdown to prevent a log full of admin queue errors and the occasional
hang when the system is shut down.
Anjali forces Tx descriptor writebacks on ITR by kicking off the SWINT
interrupt since we noticed that there are non-cache-aligned Tx
descriptors waiting in the ring while interrupts are disabled under NAPI.
Enables loopback for the FCoE VSI, so that VSIs can directly talk to each
other without going out on the wire.
Matthew fixes an LED blink issue by making sure to clear the GPIO blink
field, instead of OR'ing against zero if the field is already '1'.
Greg cleans up a function header comment.
Vasu helps biosdevname user tool to differentiate dev_port for PCoE netdev

dsa_slave_phy_setup() finds the phy for the port via device tree and
using of_phy_connect(), or it uses the fall back of taking a phy from
the switch internal mdio bus and calling phy_connect_direct(). Either
way, if a phy is found, phy_attach_direct() is called to attach the
phy to the slave device.
In dsa_slave_create(), a second call to phy_attach() is made. This

bonding and mlx4 fixes for the HA/LAG support and mlx4 reset flow
There are two fixes to the boding + mlx4 HA/LAG support from Moni and a patch from Yishai

====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The driver exposes interfaces that directly relate to HW state. Upon fatal
error, consumers of these interfaces (ULPs) that rely on completion of
all their posted work-request could hang, thereby introducing dependencies
in shutdown order. To prevent this from happening, we manage the
relevant resources (CQs, QPs) that are used by the device. Upon a fatal error,
we now generate simulated completions for outstanding WQEs that were not
completed at the time the HW was reset.
It includes invoking the completion event handler for all involved CQs so that
the ULPs will poll those CQs. When polled we return simulated CQEs with
IB_WC_WR_FLUSH_ERR return code enabling ULPs to clean up their resources and
not wait forever for completions upon receiving remove_one.
The above change requires an extra check in the data path to make sure that when
device is in error state, the simulated CQEs will be returned and no further
WQEs will be posted.

This has not been a busy release for the regulator framework, though we
do have the first parts of some ongoing work from Bjorn Andersson to
allow us to support more complex modern systems with dynamic
configuration of regulators in suspend and idle states.
- Support for device-specific properties on regulator nodes when using
simplified DT parsing in the core from Krzysztof Kozlowski.
- Restructuring of the load tracking code, intended to support future
improvements in this area for more complex system designs.
- New drivers for Maxim MAX77843 and Mediatek MT6397.
- Lots of smaller fixes and improvements.

us to run synchronous transfers in the context of the caller when there
is no contention for the bus. This improves performance in the very

- A big round of cleanups, performance and feature improvements
for the xilinx driver from Ricardo Ribalda Delgado.
- A wide range of smaller cleanups, fixes and feature improvements

tipc: new compat layer for the legacy NL API
This is a compatibility / transcoding layer for the old netlink API.
It relies on the new netlink API to collect data or perform actions
(dumpit / doit).
The main benefit of this compat layer is that it removes a lot of
complex code from the tipc core as only the new API needs to be able
harness data or perform actions. I.e. the compat layer isn't concerned
with locking or how the internal data-structures look. As long as the
new API stays relatively intact the compat layer should be fine.
The main challenge in this compat layer is the randomness of the legacy
API. Some commands send binary data and some send ASCII data, some are
very picky in optimizing there buffer sizes and some just don't care.
Most legacy commands put there data in a single TLV (data container) but some
segment the data into multiple TLV's. This list of randomness goes on and on..

There was a bad typo in commit 43759d4f42 ("random: use an improved
fast_mix() function") and I didn't notice because it "looked right", so
I saw what I expected to see when I reviewed it.
Only months later did I look and notice it's not the Threefish-inspired
mix function that I had designed and optimized.
Mea Culpa. Each input bit still has a chance to affect each output bit,
and the fast pool is spilled *long* before it fills, so it's not a total
disaster, but it's definitely not the intended great improvement.
I'm still working on finding better rotation constants. These are good
enough, but since it's unrolled twice, it's possible to get better
mixing for free by using eight different constants rather than repeating
the same four.

The first URBs are submitted during the prepare stage. When .trigger is
called, the ALSA core saves a trigger tstamp that doesn't correspond to
the actual time when the samples are submitted. The trigger_tstamp is
now updated when the first data are submitted to avoid any time offsets.
A usb-specific trigger_tstamp_pending_update flag is used for now,
at some point the flag would need to move to the ALSA core, USB
is not the only interface where silent block transfers are programmed
as part of the prepare stage, with actual data enabled when .trigger
is called.

The problem here is that we check:
if (dev >= SNDRV_CARDS)
Then we increment "dev".
if (!joystick_port[dev++])
Then we use it as an offset into a array with SNDRV_CARDS elements.
if (!request_region(joystick_port[dev], 8, "Riptide gameport")) {
This has 3 effects:
1) If you use the module option to specify the joystick port then it has
to be shifted one space over.
2) The wrong error message will be printed on failure if you have over
32 cards.
3) Static checkers will correctly complain that are off by one.

For all VSIs on a VEB, Loopback mode should be either on or off.
Our configuration requires them to be ON so that VSIs can directly
talk to each other without going out on the wire.

dev_port value for PF netdev, this helps biosdevname user tool to
