With the actual code, if a memory allocation error happens while
refilling a Rx descriptor, then the original Rx buffer is both passed
to the networking stack (in a SKB) and let in the Rx ring. This leads
to various kernel oops and crashes.
As a fix, this patch moves Rx descriptor refilling ahead of building
SKB with the associated Rx buffer. In case of a memory allocation
failure, data is dropped and the original DMA buffer is put back into
the Rx ring.

Intel Wired LAN Driver Updates 2015-07-17
This series contains updates to igb, ixgbe, ixgbevf, i40e, bnx2x,
freescale, siena and dp83640.
Jacob provides several patches to clarify the intended way to implement
both SIOCSHWTSTAMP and ethtool's get_ts_info(). It is okay to support
the specific filters in SIOCSHWTSTAMP by upscaling them to the generic
filters.
Alex Duyck provides a igb patch to pull the time stamp from the fragment
before it gets added to the skb, to avoid a possible issue in which the
fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp
being pulled after the copybreak check. Also provides a ixgbevf patch to
fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives
the advantage that the fragment does not have to be modified after it is
added to the skb.
Fan provides patches for ixgbe/ixgbevf to set the receive hash type
based on receive descriptor RSS type.
Todd provides a fix for igb where on check for link on any media other
than copper was not being detected since it was looking on the incorrect
PHY page (due to the page being used gets switched before the function
to check link gets executed).

Now that we have reworked the way we perform the PHY initialization, we

We are currently doing a full PHY initialization and even starting the
pHY state machine during bcmgenet_mii_init() which is executed in the
driver's probe function. This is convenient to determine whether we can
attach to a proper PHY device but comes at the expense of spending up to
10ms per MDIO transactions (to reach the waitqueue timeout), which slows
things down.
This also creates a sitaution where we end-up attaching twice to the
PHY, which is not quite correct either.
Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update
its error path accordingly.
Avoid printing the message "attached PHY at address 1 [...]" every time
we bring up/down the interface and remove this print since it duplicates
what the PHY driver already does for us.

Our internal GPHY might be powered off before we attempt scanning the
MDIO bus and bind a driver to it. The way we are currently determining
whether a PHY is internal or not is done *after* we have successfully
matched its driver. If the PHY is powered down, it will not respond to
the MDIO bus, so we will not be able to bind a driver to it.
Our Device Tree for GENET interfaces specifies a "phy-mode" value:
"internal" which tells if this internal uses an internal PHY or not.
If of_get_phy_mode() fails to parse the 'phy-mode' property, do an
additional manual lookup, and if we find "internal" set the
corresponding internal variable accordingly.
Replace all uses of phy_is_internal() with a check against
priv->internal_phy to avoid having to rely on whether or not
priv->phydev is set correctly.

We are currently disabling the GPHY interface during bcmgenet_close(),

fine for the first time, because we called bcmgenet_mii_config() which
took care of enabling the interface, however, bcmgenet_power_up() really
needs to power on the GPHY for correctness.
This will be particularly important as we want to move
bcmgenet_mii_probe() down to bcmgenet_open() to avoid seeing the "PHY

and can take as long as 10ms per MDIO transactions while we re-apply
workarounds because we do not yet have MDIO interrupts enabled.
phy_resume() takes care of re-apply our workarounds in case we need any,

The "follow" fail_over_mac policy is useful for multiport devices that
either become confused or incur a performance penalty when multiple
ports are programmed with the same MAC address, but the same MAC
address still may happened by this steps for this policy:
1) echo +eth0 > /sys/class/net/bond0/bonding/slaves
bond0 has the same mac address with eth0, it is MAC1.
2) echo +eth1 > /sys/class/net/bond0/bonding/slaves
eth1 is backup, eth1 has MAC2.
3) ifconfig eth0 down
eth1 became active slave, bond will swap MAC for eth0 and eth1,
so eth1 has MAC1, and eth0 has MAC2.
4) ifconfig eth1 down
there is no active slave, and eth1 still has MAC1, eth2 has MAC2.
5) ifconfig eth0 up
the eth0 became active slave again, the bond set eth0 to MAC1.
Something wrong here, then if you set eth1 up, the eth0 and eth1 will have the same
MAC address, it will break this policy for ACTIVE_BACKUP mode.
This patch will fix this problem by finding the old active slave and
swap them MAC address before change active slave.

7445E0 contains an ECO which disconnected the internal SF2 pseudo-PHY which was
known to conflict with the external pseudo-PHY of BCM53125 switches. This
motivated the need to utilize the internal SF2 MDIO controller via indirect
register reads/writes to control external Broadcom switches due to this address
conflict (both responded at address 30d).
For 7445E0, the internal pseudo-PHY of the SF2 switch got disconnected, and as
a consequence this prevents the internal SF2 MDIO bus controller from reading
data (reads back everything as 0) since the MDI line is tied low.
Fix this by making the indirect register reads and writes conditional to
7445D0, on 7445E0 we can utilize the SWITCH_MDIO controller (backed by
mdio-unimac and not the DSA created slave MII bus).
We utilize of_machine_is_compatible() here since this is the only way for use
to differentiate between these two chips in a way that does not violate layers
or becomes (too) vendor-specific.

If the bond is enslaving a device with different type it will be setup
by it, but if after being setup the enslave fails the bond doesn't
switch back its type and also keeps pointers to foreign structures that can
be long gone. Thus revert back any type changes if the enslave failed and
the bond had to change its type.
Example:
Before patch:
$ echo lo > bond0/bonding/slaves
-bash: echo: write error: Cannot assign requested address
$ ip l sh bond0

DEFAULT group default qlen 1000
link/ether 52:54:00:3f:47:69 brd ff:ff:ff:ff:ff:ff
(notice the MASTER flag is gone)
After patch:
$ echo lo > bond0/bonding/slaves
-bash: echo: write error: Cannot assign requested address

The mv88e6xxx_priv_state structure contains an fid_mask, where 1 means
the FID is free to use, 0 means the FID is in use.
This patch fixes the bit clear in mv88e6xxx_leave_bridge() when
assigning a new FID to a port.
Example scenario: I have 7 ports, port 5 is CPU, port 6 is unused (no
PHY). After setting the ports 0, 1 and 2 in bridge br0, and ports 3 and
4 in bridge br1, I have the following fid_mask: 0b111110010110 (0xf96).
Indeed, br0 uses FID 0, and br1 uses FID 3.
After setting nomaster for port 0, I get the wrong fid_mask: 0b10 (0x2).
With this patch we correctly get 0b111110010100 (0xf94), meaning port 0
uses FID 1, br0 uses FID 0, and br1 uses FID 3.

* Allow setting of adaptive coalescing setting for all types of interrupt.
* In msi & legacy intr, we use single interrupt for rx & tx. In this case
tx_coalesce_usecs is invalid. We should use only rx_coalesce_usecs.
Do not display tx_coal values for msi/intx. And do not allow user to set
this as well.
* Driver supports only tx/rx_coalesce_usec and adaptive coalesce settings.
For other values, driver does not return error. So ethtool succeeds for
unsupported values. Introduce enic_coalesce_valid() function to validate
the coalescing values.
* If user requests for coalesce value greater than what adaptor supports,
driver uses the max value. We should at least log this.

Adaptive interrupt coalescing is available for msix. This patch adds the support
for msi poll. Interface for adaptive interrupt coalescing is already added in
driver. We just did not enable it for legacy intr & msi.
enic_calc_int_moderation() & enic_set_int_moderation() are defined as static
after enic_poll. Since enic_poll needs it, move both of these function
definitions above enic_poll. No change in functionality.

imx1_pinconf_set assumes that the array of pins in struct
imx1_pinctrl_soc_info can be indexed by pin id to get the
pinctrl_pin_desc for a pin. This used to be correct up to commit
607af165c0 which removed some entries from the array and so made it
wrong to access the array by pin id.
The result of this bug is a wrong pin name in the output for small pin
ids and an oops for the bigger ones.
This patch is the result of a discussion that includes patches by Markus
Pargmann and Chris Ruehl.

It's possible to hit a race condition if interrupts are generated on a GPIO
pin when the IRQ line in question is being disabled.
If the interrupt is freed, bcm2835_gpio_irq_disable() is called which
disables the event generation sources (edge, level). If an event occurred
between the last disabling of hard IRQs and the write to the event
source registers, a bit would be set in the GPIO event detect register
(GPEDSn) which goes unacknowledged by bcm2835_gpio_irq_handler()
so Linux complains loudly.
There is no per-GPIO mask register, so when disabling GPIO interrupts
write 1 to the relevant bit in GPEDSn to clear out any stale events.

The PFC driver causes the kernel to hang on the R-Car gen2 SoC based boards
when the CPU_ALL_PORT() macro is fixed to reflect the reality, i.e. when the
GPIO space becomes actually sparse. This happens because the _GP_GPIO() macro
includes an indexed initializer which causes the "holes" (array entries filled
with all 0s) between the groups of the existing GPIOs; and the driver can't
cope with that. There seems to be no reason to use the indexed initializer,
so we can remove the index specifier and so avoid the "holes".

Commit a21763a0b1
"pinctrl: nomadik: activate strict mux mode"
put all Nomadik pin controllers to strict mode. This was
not good on the Snowball platform: the muxing of GPIOs to
different pins is done with hogs in the DTS file, and then
these GPIOs are used by offset, relying on hogs to mux the
pins. Since that means the pin controller "owns" the pins
and at the same time we have a GPIO user, this pin controller
is by definition not strict.
