4498862710 net: fman: Inline several functions into initialization
There are several small functions which were only necessary because the
initialization functions didn't have access to the mac private data. Now
that they do, just do things directly.

This moves mac-specific initialization to mac-specific files. This will
make it easier to work with individual macs. It will also make it easier

3a1a274e93 mlxbf_gige: compute MDIO period based on i1clk
This patch adds logic to compute the MDIO period based on
the i1clk, and thereafter write the MDIO period into the YU
MDIO config register. The i1clk resource from the ACPI table
is used to provide addressing to YU bootrecord PLL registers.
The values in these registers are used to compute MDIO period.
If the i1clk resource is not present in the ACPI table, then
the current default hardcorded value of 430Mhz is used.
The i1clk clock value of 430MHz is only accurate for boards
with BF2 mid bin and main bin SoCs. The BF2 high bin SoCs
have i1clk = 500MHz, but can support a slower MDIO period.

c0955bf957 ethernet: rocker: fix sleep in atomic context bug in neigh_timer_handler
The function neigh_timer_handler() is a timer handler that runs in an
atomic context. When used by rocker, neigh_timer_handler() calls
"kzalloc(.., GFP_KERNEL)" that may sleep. As a result, the sleep in
atomic context bug will happen. One of the processes is shown below:

ofdpa_fib4_add()
 ...
 neigh_add_timer()

(wait a timer)

neigh_timer_handler()
 neigh_release()
  neigh_destroy()
   rocker_port_neigh_destroy()

     ofdpa_port_neigh_destroy()
      ofdpa_port_ipv4_neigh()
       kzalloc(sizeof(.., GFP_KERNEL) //may sleep

This patch changes the gfp_t parameter of kzalloc() from GFP_KERNEL to
GFP_ATOMIC in order to mitigate the bug.

Add a dedicated instance of 'struct mlxsw_config_profile' for Spectrum-4

cf735d4c9b mlxsw: Add a helper function for getting maximum LAG ID
Currently the driver queries the maximum supported LAG ID from firmware.
This will not be accurate anymore once the driver will configure 'max_lag'
via CONFIG_PROFILE command.

For resource query, firmware returns the maximum LAG ID which is supported
by hardware. Software can configure firmware to do not allocate entries for
all the supported LAGs, and to limit LAG IDs. In this case, the resource
query will not return the actual maximum LAG ID.

Add a helper function for getting this value. In case that 'max_lag' field
was set during initialization, return the value which was used, otherwise,
query firmware for the maximum supported ID.

eb907e9779 mlxsw: Support configuring 'max_lag' via CONFIG_PROFILE
In the device, LAG identifiers are stored in the port group table (PGT).
During initialization, firmware reserves a certain amount of entries at
the beginning of this table for LAG identifiers.

In Spectrum-4, the size of the PGT table did not increase, but the maximum
number of LAG identifiers was doubled, leaving less room for others entries
(e.g., flood entries) that also reside in the PGT.

Therefore, in order to avoid a regression and as long as there is no
explicit requirement to support 256 LAGs, mlxsw driver will configure the
firmware to allocate the same amount of LAG entries (128) as in
Spectrum-{2,3}. This configuration is done using 'max_lag' field in
CONFIG_PROFILE command. Extend 'struct mlxsw_config_profile' to support
'max_lag' field and configure firmware accordingly.

A next patch will adjust Spectrum-4 to configure 'max_lag' field.

e6686745e3 nfp: add support for eeprom get and set command
Add support for eeprom get and set operation with ethtool command.
with this change, we can support commands as:

 #ethtool -e enp101s0np0 offset 0 length 6
 Offset          Values
 ------          ------
 0x0000:         00 15 4d 16 66 33

 #ethtool -E enp101s0np0 magic 0x400019ee offset 5 length 1 value 0x88

We make this change to persist MAC change during driver reload and system
reboot.

2b88354d37 nfp: check if application firmware is indifferent to port speed
A new tlv type is introduced to indicate if application firmware is
indifferent to port speed, and inform management firmware of the
result.

And the result is always true for flower application firmware since
it's indifferent to port speed from the start and will never change.

62fad9e610 nfp: propagate port speed from management firmware
In future releases the NIC application firmware may be indifferent to port
speeds - not built for specific port speeds - and consequently it will not
be able to report VF port speeds to the driver without first learning them.
With this change, the driver will pass the speed of physical ports from
management firmware to application firmware, and the latter will copy the
speed of port 0 to all the active VFs. So that the driver can get VF port
speed as before.

The port speed of a VF may be requested from userspace using:

  ethtool <vf-intf>

278d3ba615 net: Use u64_stats_fetch_begin_irq() for stats fetch.
On 32bit-UP u64_stats_fetch_begin() disables only preemption. If the
reader is in preemptible context and the writer side
(u64_stats_update_begin*()) runs in an interrupt context (IRQ or
softirq) then the writer can update the stats during the read operation.
This update remains undetected.

Use u64_stats_fetch_begin_irq() to ensure the stats fetch on 32bit-UP
are not interrupted by a writer. 32bit-SMP remains unaffected by this
change.

Someone managed to collect the AER log and it's caused by MSI:

The MSI is probably raised by incoming packets, so power down the device
and disable bus mastering to stop the traffic, as user confirmed this
approach works.

In addition to that, be extra safe and cancel reset task if it's running.
