Andrew Lunn 232e15e1d7 net: xgene: Move shared header file into include/linux
This header file is currently included into the ethernet driver via a
relative path into the PHY subsystem. This is bad practice, and causes
issues for the upcoming move of the MDIO driver. Move the header file
into include/linux to clean this up.

v2:
Move header to include/linux/mdio

Christophe JAILLET 5a44c71ccd drivers: net: xgene: Fix the order of the arguments of 'alloc_etherdev_mqs()'
'alloc_etherdev_mqs()' expects first 'tx', then 'rx'. The semantic here
looks reversed.

Reorder the arguments passed to 'alloc_etherdev_mqs()' in order to keep
the correct semantic.

In fact, this is a no-op because both XGENE_NUM_[RT]X_RING are 8.

Michael S. Tsirkin 0290bd291c netdev: pass the stuck queue to the timeout handler
This allows incrementing the correct timeout statistic without any mess.
Down the road, devices can learn to reset just the specific queue.

The patch was generated with the following script:

use strict;
use warnings;

 2) allow making references to nodes other than device nodes in ACPI.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

This change fixes following problem

[    1.827940] xgene-enet: probe of 1f210030.ethernet failed with error -2

which leads to a missing ethernet interface (reproducable at least on
Gigabyte MP30-AR0 and APM Mustang systems).

The check for a valid clk resource fails, because DT doesn't provide a
clock for sgenet1. But the driver doesn't use this clk, if the ethernet
port is connected via SGMII. Therefore this patch avoids probing for clk
on SGMII interfaces.

On DT systems the driver require a clock, but the probe just print a

To fix this crash and properly handle probe deferals only ignore the
missing clock if DT isn't used or if the clock doesn't exist.

    drivers/net/ethernet/apm/xgene/xgene_enet_main.c:297: warning: ‘mss_index’ may be used uninitialized in this function

Using a separate variable to track success may confuse the compiler.
Preinitialize mss_index with -EBUSY and check for negative error values
instead to kill the warning.

Arnd Bergmann 1f3d62090d xgene_enet: remove bogus forward declarations
The device match tables for both the xgene_enet driver and its phy driver
have forward declarations that declare an array without a length, leading
to a clang warning when they are not followed by an actual defitinition:

drivers/net/ethernet/apm/xgene/../../../phy/mdio-xgene.h:135:34: warning: tentative array definition assumed to have one element
drivers/net/ethernet/apm/xgene/xgene_enet_main.c:33:36: warning: tentative array definition assumed to have one element

The declarations for the mdio driver are even in a header file, so they
cause duplicate definitions of the tables for each file that includes
them.

This removes all four forward declarations and moves the actual
definitions up a little, so they are in front of their first user. For
the OF match tables, this means having to remove the #ifdef around them,
and passing the actual structure into of_match_device(). This has no
effect on the generated object code though, as the of_match_device
function has an empty stub that does not evaluate its argument, and
the symbol gets dropped either way.

stephen hemminger bc1f44709c net: make ndo_get_stats64 a void function
The network device operation for reading statistics is only called
in one place, and it ignores the return value. Having a structure
return value is potentially confusing because some future driver could
incorrectly assume that the return value was used.

Fix all drivers with ndo_get_stats64 to have a void function.

Arnd Bergmann f006b2c5df net: xgene: avoid bogus maybe-uninitialized warning
In some configurations, gcc cannot trace the state of variables
across a spin_unlock() barrier, leading to a warning about
correct code:

xgene_enet_main.c: In function 'xgene_enet_start_xmit':
../../../phy/mdio-xgene.h:112:14: error: 'mss_index' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Here we can trivially move the assignment before that spin_unlock,
which reliably avoids the warning.

Arnd Bergmann dece303fa3 net: xgene: move xgene_cle_ptree_ewdn data off stack
The array for initializing the cle is set up on the stack with
almost entirely constant data and then passed to a function that
converts it into HW specific bit patterns. With the latest
addition, the size of this array has grown to the point that
we get a warning about potential stack overflow in allmodconfig
builds:

xgene_enet_cle.c: In function ‘xgene_enet_cle_init’:
xgene_enet_cle.c:836:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

Looking a bit deeper at the usage, I noticed that the only modification
of the data is in dead code, as we don't even use the cle module
for phy_mode other than PHY_INTERFACE_MODE_XGMII. This means we
can simply mark the structure constant and access it directly rather
than passing the pointer down through another structure, making
the code more efficient at the same time as avoiding the
warning.
