5e999fb43e ixgbe: Remove MAC X550EM_X 1Gbase-t led_[on|off] support
Since FW configures the PHY and MAC X550EM_X has no
PHY access, led_[on|off] is not supported with the 1Gbase-t design.

Removed MAC X550EM_X 1Gbase-t led_[on|off] support by setting
function pointers to NULL and added NULL pointer checks. Also set
init_led_link_act to NULL and added NULL pointer check.

This CallTrace occurred on 32-bit kernel with CONFIG_PROVE_LOCKING
enabled.

This happens at ixgbe driver probe hardware stage, when comes to
ixgbe_get_stats64, the seqcount/seqlock still not initialize, although
this was initialize in TX/RX resources setup routin, but it was too late,
then lockdep give this Warning.

To fix this, move the u64_stats_init function to driver probe stage,
which before we get the status of seqcount and after the RX/TX ring
was finished init.

9711164d03 Merge branch 'net-qualcomm-add-QCA7000-UART-driver'
Stefan Wahren says:

====================
net: qualcomm: add QCA7000 UART driver

The Qualcomm QCA7000 HomePlug GreenPHY supports two interfaces:
UART and SPI. This patch series adds the missing support for UART.

This driver based on the Qualcomm code [1], but contains some changes:
* use random MAC address per default
* use net_device_stats from device
* share frame decoding between SPI and UART driver
* improve error handling
* reimplement tty_wakeup with work queue (based on slcan)
* use new serial device bus instead of ldisc

The patches 1 - 3 are just for clean up and are not related to
the UART support. Patch 4 adds SET_NETDEV_DEV() to qca_spi.
Patches 5 - 16 prepare the existing QCA7000 code for UART support.
The last patch contains the new driver.

The code itself has been tested on a Freescale i.MX28 board and
a Raspberry Pi Zero.

Changes in v8:
  * add necessary header includes to qca_7k.c in order to reflect
    dependencies

Changes in v7:
  * fix race between tx workqueue and device deregistration (reported by Lino)

Bogdan Purcareata says:

====================
net: phy: Support managed Cortina phys

So far, the Cortina family phys (CS4340 in this particular case) are only
supported in fixed link mode (via fixed_phy_register). The generic 10G
phy driver does not work well with the phylib state machine, when the phy
is registered via of_phy_connect. This prohibits the user from describing the
phy nodes in the device tree.

In order to support this scenario, and to properly describe the board
device tree, add a minimal Cortina driver that reads the status from the
right register. With the generic 10G C45 driver, the kernel will print
messages like:
[    0.226521] mdio_bus 8b96000: Error while reading PHY16 reg at 1.6
[    0.232780] mdio_bus 8b96000: Error while reading PHY16 reg at 1.5

v3 -> v4:
- Add trademark info.
- Minor documentation entry consistency nit.

v2 -> v3:
- Add documentation entry.

v1 -> v2:
- Change approach for getting the phy_id from hacking get_phy_c45_ids to
  describing the device in the device tree via ethernet-phy-id.

More patch version changes per individual patches.

15b9e5330f net: phy: Add Cortina CS4340 driver
Add basic support for Cortina PHY drivers. Support only CS4340 for now.
The phys are not compatible with IEEE 802.3 clause 22/45 registers.

Implement proper read_status support. The generic 10G phy driver causes
bus register access errors.

The driver should be described using the "ethernet-phy-id" device tree
compatible.

eb67e07ac6 Merge branch 'qed-DCBx-and-Attentions-series'
Yuval Mintz says:

====================
qed: DCBx and Attentions series

The series contains 2 major components [& some odd bits]:
 - The first 3 patches are DCBx-related, containg missing bits in the
   implementation, correcting existing API and removing code no longer
   necessary.
 - Most of the remaining patches are interrupt/hw-attention related,
   adding some differeneces relating to QL41xxx and QL45xxx differences.
   While at it, they also remove a large chunk of unnecessary structure
   definitions.

The series also contain a patch [#10] that was accidently missing
from a previous series.

9790c35e96 qed: Mask parities after occurance
Parities might exhibit a flood behavior since we re-enable the
attention line without preventing the parity from re-triggering the
assertion.
Mask the source in AEU until the parity would be handled.

6010179da3 qed: Print multi-bit attentions properly
In strucuture reflecting the AEU hw block some entries
represent multiple HW bits, and the associated name is in fact
a pattern.
Today, whenever such an attention would be asserted the resulted
prints would show the pattern string instead of indicating which
of the possible bits was set.

ba36f718c7 qed: Diffrentiate adapter-specific attentions
There are 4 attention bits in AEU that have different meaning
for QL45xxx and QL41xxx adapters.

Instead of doing a massive infrastructure change in favor of these
bits, we implement a point fix where only those four would change
meaning dependent on the adapter involved.

88072fd400 qed: QL41xxx VF MSI-x table
The QL41xxx adapters' PCI allows a single configuration for the
MSI-x table size of all child VFs of a given PF.
The existing code wouldn't cause the management firmware to set
that value, meaning the VFs would retain the default MSI-x table
size.

Introduce a new scheme so that whenever a VF is enabled, driver
would set the number of MSI-x to be the maximum over the various
VFs' needs.

38b23e43ee qed: Don't inherit RoCE DCBx for V2
Older firmware used by device didn't distinguish between RoCE and RoCE
V2 from DCBx configuration perspective, and as a result we've used to
take a the RoCE-related configuration and apply to it for both.

Since we now support configuring each its own values, there's no reason
to reflect [& configure] that both are using the same.
