Kurt Kanzenbach c6d5f19330 net: stmmac: Calculate CDC error only once
The clock domain crossing error (CDC) is calculated at every fetch of Tx or Rx
timestamps. It includes a division. Especially on arm32 based systems it is
expensive. It also requires two conditionals in the hotpath.

Add a compensation value cache to struct plat_stmmacenet_data and subtract it
unconditionally in the RX/TX functions which spares the conditionals.

The value is initialized to 0 and if supported calculated in the PTP
initialization code.

implementations. Over 2.5yrs later we still have no real users
upstream. Hardwire the generic implementation for now, we can
revert once real users materialize. (rocker is a test vehicle,
not a user.)

We need to drop the optimization on the sysfs side, because
unlike ndos priv_flags will be changed at runtime, so we'd
need READ_ONCE/WRITE_ONCE everywhere..

Gerhard Engleder 75e4720651 tsnep: Fix set MAC address
Commit 4dfb998264 ("tsn:  Fix build.") fixed compilation with const
dev_addr. In tsnep_netdev_set_mac_address() the call of ether_addr_copy()
was replaced with dev_set_mac_address(), which calls
ndo_set_mac_address(). This results in an endless recursive loop because
ndo_set_mac_address is set to tsnep_netdev_set_mac_address.

Call eth_hw_addr_set() instead of dev_set_mac_address() in
ndo_set_mac_address()/tsnep_netdev_set_mac_address() to copy the address
as intended.

David S. Miller 33e2ec5232 Merge branch 'qca8k-mirror-and-lag-support'
Ansuel Smith says:

====================
Add mirror and LAG support to qca8k

With the continue of adding 'Multiple feature to qca8k'

The switch supports mirror mode and LAG.
In mirror mode a port is set as mirror and other port are configured
to both igress or egress mode. With no port configured for mirror,
the mirror port is disabled and reverted to normal port.

The switch supports max 4 LAG with 4 different member max.
Current supported mode is Hash mode in both L2 or L2+3 mode.
There is a problematic implementation for the hash mode where
with multiple LAG configured, someone has to remove them to
change the hash mode as it's global.
When a member of the LAG is disconnected, the traffic is redirected
to the other port.

Some warning are present from checkpatch but can't really be fixed
as it would result in making the regs less readable.
(They really did their best with the LAG reg logic and complexity)

Ansuel Smith def975307c net: dsa: qca8k: add LAG support
Add LAG support to this switch. In Documentation this is described as
trunk mode. A max of 4 LAGs are supported and each can support up to 4
port. The current tx mode supported is Hash mode with both L2 and L2+3
mode.
When no port are present in the trunk, the trunk is disabled in the
switch.
When a port is disconnected, the traffic is redirected to the other
available port.
The hash mode is global and each LAG require to have the same hash mode
set. To change the hash mode when multiple LAG are configured, it's
required to remove each LAG and set the desired hash mode to the last.
An error is printed when it's asked to set a not supported hadh mode.

Jeremy Kerr a0c2ccd9b5 mctp: Add MCTP-over-serial transport binding
This change adds a MCTP Serial transport binding, as defined by DMTF
specificiation DSP0253 - "MCTP Serial Transport Binding". This is
implemented as a new serial line discipline, and can be attached to
arbitrary tty devices.

From the Kconfig description:

  This driver provides an MCTP-over-serial interface, through a
  serial line-discipline, as defined by DMTF specification "DSP0253 -
  MCTP Serial Transport Binding". By attaching the ldisc to a serial
  device, we get a new net device to transport MCTP packets.

  This allows communication with external MCTP endpoints which use
  serial as their transport. It can also be used as an easy way to
  provide MCTP connectivity between virtual machines, by forwarding
  data between simple virtual serial devices.

  Say y here if you need to connect to MCTP endpoints over serial. To
  compile as a module, use m; the module will be called mctp-serial.

Once the N_MCTP line discipline is set [using ioctl(TCIOSETD)], we get a
new netdev suitable for MCTP communication.

The 'mctp' utility[1] provides a simple wrapper for this ioctl, using
'link serial <device>':

  # mctp link serial /dev/ttyS0 &
  # mctp link
  dev lo index 1 address 0x00:00:00:00:00:00 net 1 mtu 65536 up

====================
mlxsw: Various updates

Patch #1 removes deadcode reported by Coverity.

Patch #2 adds a shutdown method in the PCI driver to ensure the kexeced
kernel starts working with a device that is in a sane state.

Danielle Ratson c1020d3cf4 mlxsw: pci: Add shutdown method in PCI driver
On an arm64 platform with the Spectrum ASIC, after loading and executing
a new kernel via kexec, the following trace [1] is observed. This seems
to be caused by the fact that the device is not properly shutdown before
executing the new kernel.

Fix this by implementing a shutdown method which mirrors the remove
method, as recommended by the kexec maintainer [2][3].

David S. Miller 3b0e04140b Merge branch 'qca8k-next'
Ansuel Smith says:

====================
Multiple cleanup and feature for qca8k

This is a reduced version of the old massive series.
Refer to the changelog to know what is removed from this.

We clean and convert the driver to GENMASK FIELD_PREP to clean multiple
use of various naming scheme. (example we have a mix of _MASK, _S _M,
and various name) The idea is to ""simplify"" and remove some shift and
data handling by using FIELD API.
The patch contains various checkpatch warning and are ignored to not
create more mess in the header file. (fixing the too long line warning
would results in regs definition less readable)

We conver the driver to regmap API as ipq40xx SoC is based on the same
reg structure and we need to generilize the read/write access to split
the driver to commond and specific code.

The conversion to regmap is NOT done for the read/write/rmw operation,
the function are reworked to use the regmap helper instead.
This is done to keep the patch delta low but will come sooner or later
when the code will be split.
Any new feature will directly use the regmap helper and the reg
set/clear and the busy wait function are migrated to regmap helper as
the use of these function is low.

We also add a minor patch for MIB counter as qca8337 is missing 2 extra
counter, support for mdb and ageing settings.

v3:
- Try to reduce regmap conversion patch
v2:
- Move regmap init to sw_probe instead of moving switch id check.
- Removed LAGs, mirror extra features will come later in another
  smaller series.
- Squash 2 ageing patch
- Add more description about the regmap patch
- Rework mdb patch to do operation under the same lock

If every port is removed from the port mask, the rule is removed.
The rule is set STATIC in the ARL table (aka it doesn't age) to not be

Ansuel Smith 8b5f3f29a8 net: dsa: qca8k: initial conversion to regmap helper
Convert any qca8k set/clear/pool to regmap helper and add
missing config to regmap_config struct.
Read/write/rmw operation are reworked to use the regmap helper
internally to keep the delta of this patch low. These additional
function will then be dropped when the code split will be proposed.

Ipq40xx SoC have the internal switch based on the qca8k regmap but use
mmio for read/write/rmw operation instead of mdio.
In preparation for the support of this internal switch, convert the
driver to regmap API to later split the driver to common and specific
code. The overhead introduced by the use of regamp API is marginal as the
internal mdio will bypass it by using its direct access and regmap will be
used only by configuration functions or fdb access.

Replace the existing empty member position markers "headers_start" and

to more easily reason about sizes, and improve readability.
