fixed_phy_set_link_update() contains an early check against a NULL
callback pointer, which basically prevents us from removing any
previous callback we may have set. The users of the fp->link_update
callback deal with a NULL callback just fine, so we really want to allow
"removing" a link_update callback to avoid dangling callback pointers
during e.g: module removal.

The kernel forcefully applies MTU values received in router
advertisements provided the new MTU is less than the current. This
behavior is undesirable when the user space is managing the MTU. Instead
a sysctl flag 'accept_ra_mtu' is introduced such that the user space
can control whether or not RA provided MTU updates should be applied. The
default behavior is unchanged; user space must explicitly set this flag
to 0 for RA MTUs to be ignored.

Fixes and improvements for recent fib_trie updates

While performing testing and prepping the next round of patches I found a
few minor issues and improvements that could be made.

These changes should help to reduce the overall code size and improve the
performance slighlty as I noticed a 20ns or so improvement in my worst-case
testing which will likely only result in a 1ns difference with a standard
sized trie.

While doing further work on the fib_trie I noted a few items.

First I was using calls that were far more complicated than they needed to
be for determining when to push/pull the suffix length.  I have updated the
code to reflect the simplier logic.

The second issue is that I realised we weren't necessarily handling the
case of a leaf_info struct surviving a flush.  I have updated the logic so
that now we will call pull_suffix in the event of having a leaf info value
left in the leaf after flushing it.

This patch really does two things.

First it pulls the logic for determining if we should collapse one node out
of the tree and the actual code doing the collapse into a separate pair of
functions.  This helps to make the changes to these areas more readable.

Second it encodes the upper 32b of the empty_children value onto the
full_children value in the case of bits == KEYLENGTH.  By doing this we are
able to handle the case of a 32b node where empty_children would appear to
be 0 when it was actually 1ul << 32.

This change corrects an issue where if inflate or halve fails we were
exiting the resize function without at least updating the slen for the
node.  To correct this I have moved the update of max_size into the while

or halve.

This patch addresses two issues.

The first issue is the fact that I believe I had the RCU freeing sequence
slightly out of order.  As a result we could get into an issue if a caller
went into a child of a child of the new node, then backtraced into the to be
freed parent, and then attempted to access a child of a child that may have
been consumed in a resize of one of the new nodes children.  To resolve this I
have moved the resize after we have freed the oldtnode.  The only side effect
of this is that we will now be calling resize on more nodes in the case of
inflate due to the fact that we don't have a good way to test to see if a
full_tnode on the new node was there before or after the allocation.  This
should have minimal impact however since the node should already be
correctly size so it is just the cost of calling should_inflate that we
will be taking on the node which is only a couple of cycles.

The second issue is the fact that inflate and halve were essentially doing
the same thing after the new node was added to the trie replacing the old
one.  As such it wasn't really necessary to keep the code in both functions
so I have split it out into two other functions, called replace and
update_children.

In doing performance testing and analysis of the changes I recently found
that by shifting the index I had created an unnecessary dependency.

I have updated the code so that we instead shift a mask by bits and then
just test against that as that should save us about 2 CPU cycles since we
can generate the mask while the key and pos are being processed.

mlx4: Fix and enhance the device reset flow

This series from Yishai Hadas fixes the device reset flow and adds SRIOV support.

Reset flows are required whenever a device experiences errors, is unresponsive,
or is not in a deterministic state. In such cases, the driver is expected to
reset the HW and continue operation. When SRIOV is enabled, these requirements
apply both to PF and VF devices.

Currently, the mlx4 reset flow doesn't work properly: when a fatal error is
detected on the FW internal buffer the chip is not reset and stays in its
bad state. There are cases that assumed to be fatal such as non-responsive FW,
errors via closing commands but are not handled today.

The AER mechanism should also be fixed:
- It should use mlx4_load_one instead of __mlx4_init_one which is done
  upon HCA probing.
- It must be aligned with concurrent catas flow, mark device to be in
  an error state, reset chip, etc.
- Port types should be restored to their original values before error occurred.

In addition, there the SRIOV use-case isn't supported.

In above cases when the device state becomes fatal we must act as follows:
1) Reset the chip and mark the HW device state as in fatal error.
2) Wake up any pending commands, preventing new ones to come in.
3) Restart the software stack.

We also address the SRIOV mode as follows: In case the PF detects a fatal error,
it lets VFs know about that, then both itself and VFs are restarted asynchronously.
However, in case only the VF encountered a fatal case or forced to be reset, they
reset the VF stuff and then restart software.

changes from V0:

No need to call pci_disable_device upon permanent PCI error. This will
be done as part of mlx4_remove_one which is called later once we
return PCI_ERS_RESULT_DISCONNECT from the pci error handler.

Initial toggle value should use only the T bit and not the whole byte value.
Not doing so sometimes broke SRIOV as of junky value seen by the VF as a
non-ready comm channel
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

When SRIOV commands are executed over the comm-channel and get
a fatal error (e.g. timeout, closing command failure) the VF enters
into error state and reset flow is activated.

To be able to recognize whether the failure was on a closing command, the
operational code for the given VHCR command is used. Once the device entered
into an error state we prevent redundant error messages from being printed.

In SRIOV, both the PF and the VF may attempt device recovery whenever they
assume that the device is not functioning.  When the PF driver resets the
device, the VF should detect this and attempt to reinitialize itself.

The VF must be able to reset itself under all circumstances, even
if the PF is not responsive.

The VF shall reset itself in the following cases:

1. Commands are not processed within reasonable time over the communication channel.
This is done considering device state and the correct return code based on
the command as was done in the native mode, done in the next patch.

2. The VF driver receives an internal error event reported by the PF on the
communication channel. This occurs when the PF driver resets the device or
when VF is out of sync with the PF.

Add 'VF reset' capability, which allows the VF to reinitialize itself even when the
PF is not responsive.

As PF and VF may run their reset flow simulantanisly, there are several cases
that are handled:
- Prevent freeing VF resources upon FLR, when PF is in its unloading stage.
- Prevent PF getting VF commands before it has finished initializing its resources.
- Upon VF startup, check that comm-channel is online before sending
  commands to the PF and getting timed-out.

We need to manage interface state to sync between reset flow and some other
relative cases such as remove_one. This has to be done to prevent certain
races. For example in case software stack is down as a result of unload call,
the remove_one should skip the unload phase.

Implement the remove_one case, handling AER and other cases comes next.

The interface can be up/down, upon remove_one, the state will include an extra
bit indicating that the device is cleaned-up, forcing other tasks to finish
before the final cleanup.

We activate reset flow upon command fatal errors, when the device enters an
erroneous state, and must be reset.

The cases below are assumed to be fatal: FW command timed-out, an error from FW
on closing commands, pci is offline when posting/pending a command.

In those cases we place the device into an error state: chip is reset, pending
commands are awakened and completed immediately. Subsequent commands will
return immediately.

The return code in the above cases will depend on the command. Commands which
free and close resources will return success (because the chip was reset, so
callers may safely free their kernel resources). Other commands will return -EIO.

Since the device's state was marked as error, the catas poller will
detect this and restart the device's software stack (as is done when a FW
internal error is directly detected). The device state is protected by a
persistent mutex lives on its mlx4_dev, as such no need any more for the
hcr_mutex which is removed.

Intel Wired LAN Driver Updates 2015-01-22

This series contains updates to e1000, e1000e, igb, fm10k and virtio_net.

Asaf Vertz provides a fix for e1000 to future-proof the time comparisons
by using time_after_eq() instead of plain math.

Mathias Koehrer provides a fix for e1000e to add a check to e1000_xmit_frame()
to ensure a work queue will not be scheduled that has not been initialized.

Jacob adds the use of software timestamping via the virtio_net driver.

Alex Duyck cleans up page reuse code in igb and fm10k.  Cleans up the
page reuse code from getting into a state where all the workarounds
needed are in place as well as cleaning up oversights, such as using
__free_pages instead of put_page to drop a locally allocated page.

Richard Cochran provides 4 patches for igb dealing with time sync.
First provides a helper function since the code that handles the time
sync interrupt is repeated in three different places.  Then serializes
the access to the time sync interrupt since the registers may be
manipulated from different contexts.  Enables the use of i210 device
interrupt to generate an internal PPS event for adjusting the kernel
system time.  The i210 device offers a number of special PTP hardware
clock features on the Software Defined Pins (SDPs), so added support for
two of the possible functions (time stamping external events and
periodic output signals).

Or Gerlitz fixes fm10k from double setting of NETIF_F_SG since the
networking core does it for the driver during registration time.

Joe Stringer adds support for up to 104 bytes of inner+outer headers in
fm10k and adds an initial check to fail encapsulation offload if these
are too large.

Matthew increases the timeout for the data path reset based on feedback
from the hardware team, since 100us is too short of a time to wait for
the data path reset to complete.

Alexander Graf provides a fix for igb to indicate failure on VF reset
for an empty MAC address, to mirror the behavior of ixgbe.

Florian Westphal updates e1000 and e1000e to support txtd update delay
via xmit_more, this way we won't update the Tx tail descriptor if the
queue has not been stopped and we know at least one more skb will be
sent right away.

functions is to get the setting for checksum (enabled or zero).
This patch removes the argument and and adds a nocheck argument
for checksum setting. This eliminates the unnecessary dependency
on a UDP socket for UDP tunnel transmit.

   The driver now uses the default voltage settings found in the devicetree,
   which are applied throught the regulator framework.
2. The regulator name used to power on or power off the phy was put in the devicetree
   variable "phy_regulator", which is not standard and added a lot of code for nothing.
   The driver now uses the devicetree property "phy-supply" and the corresponding functions
   to manipulate this regulator.

The corresponding devicetree files are also updated. As this new binding for
rk3288 has not been released with any official kernel yet (not until 3.20),
I don't need to care about keeping compatibility with the old non standard property.

As no property for phy regulator was documented in this dt-binding documentation,
this commit adds an entry for the optional property phy-supply.

Currently, dwmac-rk uses a custom propety "phy_regulator" to get the name of the
right regulator to use to power on or power off the phy. This commit converts the
driver to use phy-supply devicetree property and the corresponding API, it cleans
the code a bit and make it simpler to maintain. This also replaces the property
phy_regulator by the standard property phy-supply in rk3288-evb-rk808.dts.

As these settings can be directly expressed from devicetree for both fixed
regulators and pmic-integrated regulators, it is more standard to set them
from dts and let the regulator framework use the right voltage informations
when it is used in the driver.
