Add support for DT property "microchip,led-modes", a vector of zero
to four cells (u32s) in the range 0-15, each of which sets the mode
for one of the LEDs. Some possible values are:

    0=link/activity          1=link1000/activity
    2=link100/activity       3=link10/activity
    4=link100/1000/activity  5=link10/1000/activity
    6=link10/100/activity    14=off    15=on

These values are given symbolic constants in a dt-bindings header.

Also use the presence of the DT property to indicate that the
LEDs should be enabled - necessary in the event that no valid OTP
or EEPROM is available.

qed* : Use trust mode to override forced MAC

This patchset adds a support to override forced MAC (MAC set by PF for a VF)
when trust mode is enabled using

First patch adds a real change to use .ndo_set_vf_trust to override forced MAC
and allow user to change VFs from VF interface itself.

Second patch takes care of a corner case, where MAC change from VF won't
take effect when VF interface is down, by introducing a new TLV
(a way to send message from VF to PF) to give a hint to PF to update
its bulletin board.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

There may be a need for VF driver to request PF to explicitly update its
bulletin with a MAC address.
e.g. When user assigns a MAC address to VF while VF is still down,
and PF's bulletin board contains different MAC address, in this case,
when VF's interface is brought up, it gets loaded with MAC address from
bulletin board which is not desirable.

To handle this corner case, we need a new TLV to request PF to update
its bulletin board with suggested MAC.

This request will be honored only for trusted VFs.

As per existing behavior, when PF sets a MAC address for a VF

MAC address afterwards.
This puts the limitation on few use cases such as bonding of VFs,
where bonding driver asks VF to change its MAC address.

This patch uses a VF trust mode to allow VF to change its MAC address
in spite PF has set a forced MAC for that VF.

geneve: verify user specified MTU or adjust with a lower device

The first two patches don't introduce any functional changes and
contain minor cleanups for code readability.

The last one adds a new function geneve_link_config() similar to the
other tunnels. The function will be used on a new link creation or
when 'remote' parameter is changed. It adjusts a user specified MTU
or, if it finds a lower device, tunes the tunnel MTU using it.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Currently, on a new link creation or when 'remote' address parameter
is updated, an MTU is not changed and always equals 1500. When a lower
device has a larger MTU, it might not be efficient, e.g. for UDP, and
requires the manual MTU adjustments to match the MTU of the lower
device.

This patch tries to automate this process, finds a lower device using
the 'remote' address parameter, then uses its MTU to tune GENEVE's MTU:
  * on a new link creation
  * when 'remote' parameter is changed

Also with this patch, the MTU from a user, on a new link creation, is
passed to geneve_change_mtu() where it is verified, and MTU adjustments
with a lower device is skipped in that case. Prior that change, it was
possible to set the invalid MTU values on a new link creation.

tipc: Confgiuration of MTU for media UDP

Systematic measurements have shown that an emulated MTU of 14k for
UDP bearers is the optimal value for maximal throughput. Accordingly,
the default MTU of UDP bearers is changed to 14k.

We also provide users with a fallback option from this value,
by providing support to configure MTU for UDP bearers. The following
options are introduced which are symmetrical to the design of
confguring link tolerance.

- Configure media with new MTU value, which will take effect on
links going up after the moment it was configured. Alternatively,
the bearer has to be disabled and re-enabled, for existing links to
reflect the configured value.

- Configure bearer with new MTU value, which take effect on
running links dynamically.

Please note:
- User has to change MTU at both endpoints, otherwise the link
will fall back to smallest MTU after a reset.
- Failover from a link with higher MTU to a link with lower MTU
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Currently, we have option to configure MTU of UDP media. The configured
MTU takes effect on the links going up after that moment. I.e, a user
has to reset bearer to have new value applied across its links. This is
confusing and disturbing on a running cluster.

We now introduce the functionality to change the default UDP bearer MTU
in struct tipc_bearer. Additionally, the links are updated dynamically,
without any need for a reset, when bearer value is changed. We leverage
the existing per-link functionality and the design being symetrical to
the confguration of link tolerance.

was determined by experimentation and found to have a higher throughput
than 16k. MTU for UDP bearers are assigned the above set value of

This patch adds support for specifying system controller that configures
phy-mode setting.

According to the DT property "phy-mode", it's necessary to configure the
controller, which is used to choose the settings of the MAC suitable,
for example, mdio pin connections, internal clocks, and so on.

Supported phy-modes are SoC-dependent. The driver allows phy-mode to set
"internal" if the SoC has a built-in PHY, and {"mii", "rmii", "rgmii"}
if the SoC supports each mode. So we have to check whether the phy-mode
is valid or not.

This adds the following features for each SoC:
- check whether the SoC supports the specified phy-mode
- configure the controller accroding to phy-mode

The DT property accepts one argument to distinguish them for multiple MAC
instances.

ethernet@65000000 {
	...
	socionext,syscon-phy-mode = <&soc_glue 0>;

When the link is becoming up for Pro4 SoC, the kernel is stalled
due to some missing clocks and resets.

The AVE block for Pro4 is connected to the GIO bus in the SoC.
Without its clock/reset, the access to the AVE register makes the
system stall.

In the same way, another MAC clock for Giga-bit Connection and
the PHY clock are also required for Pro4 to activate the Giga-bit feature
and to recognize the PHY.

To satisfy these requirements, this patch adds support for multiple clocks
and resets, and adds the clock-names and reset-names to the binding because
we need to distinguish clock/reset for the AVE main block and the others.

Also, make the resets a required property. Currently, "reset is
optional" relies on that the bootloader or firmware has deasserted
the reset before booting the kernel.  Drivers should work without
such expectation.

New network driver for Amiga X-Surf 100 (m68k)

[This is a resend of my v3 series which was based on the wrong version and
tree. Only substantial change is to Asix AX99796B PHY driver.]

This patch series adds support for the Individual Computers X-Surf 100
network card for m68k Amiga, a network adapter based on the AX88796 chip set.

The driver was originally written for kernel version 3.19 by Michael Karcher
(see CC:), and adapted to 4.16+ for submission to netdev by me. Questions
regarding motivation for some of the changes are probably best directed at
Michael Karcher.

The driver has been tested by Adrian <glaubitz@physik.fu-berlin.de> who will
send his Tested-by tag separately.

A few changes to the ax88796 driver were required:
- to read the MAC address, some setup of the ax99796 chip must be done,
- attach to the MII bus only on device open to allow module unloading,
- allow to supersede ax_block_input/ax_block_output by card-specific
  optimized code,
- use an optional interrupt status callback to allow easier sharing of the
  card interrupt,
- set IRQF_SHARED if platform IRQ resource is marked shareable

The Asix Electronix PHY used on the X-Surf 100 is buggy, and causes the
software reset to hang if the previous command sent to the PHY was also
a soft reset. This bug requires addition of a PHY driver for Asix PHYs
to provide a fixed .soft_reset function, included in this series.

Some additional cleanup:
- do not attempt to free IRQ in ax_remove (complements 82533ad9),
- clear platform drvdata on probe fail and module remove.

Changes since v1:

Raised in review by Andrew Lunn:
- move MII code around to avoid need for forward declaration,
- combine patches 2 and 7 to add cleanup in error path

Changes since v2:

- corrected authorship attribution to Michael Karcher

Suggested by Geert Uytterhoeven:
- use ei_local->reset_8390() instead of duplicating ax_reset_8390(),
- use %pR to format struct resource pointers,
- assign pdev and xs100 pointers in declaration,
- don't split error messages,
- change Kconfig logic to only require XSURF100 set on Amiga

Suggested by Andrew Lunn:
- add COMPILE_TEST to ax88796 Kconfig options,
- use new Asix PHY driver for X-Surf 100

Suggested by Andrew Lunn/Finn Thain:
- declare struct sk_buff in ax88796.h,
- correct whitespace error in ax88796.h

Changes since v3:

- various checkpatch cleanup
