Number of drivers use eth_random_addr(netdev->dev_addr)
thus writing to netdev->dev_addr directly, and not setting
the address type. Switch them to eth_hw_addr_random().

This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.
No functional changes.

Expose SMA and U.FL connectors as ptp_pins on E810-T based adapters and
allow controlling them.
E810-T adapters are equipped with:
- 2 external bidirectional SMA connectors
- 1 internal TX U.FL
- 1 internal RX U.FL
U.FL connectors share signal lines with the SMA connectors. The TX U.FL1
share the line with the SMA1 and the RX U.FL2 share line with the SMA2.
This dependence is controlled by the ice_verify_pin_e810t.
Additionally add support for the E810-T-based devices which don't use the
SMA/U.FL controller. If the IO expander is not detected don't expose pins
and use 2 predefined 1PPS input and output pins.

The Qdisc code in mlxsw used to report a number of packets ECN-marked on a
port. Because reporting a per-port value as a per-TC value was misleading,
this was removed in commit 8a29581eb001 ("mlxsw: spectrum: Move the
ECN-marked packet counter to ethtool").
On Spectrum-3, a per-TC number of ECN-marked packets is available in per-TC
congestion counter group. Add a new array for the ECN counter, fetch the
values from the per-TC congestion group, and pick the value indicated by
tclass_num as appropriate.
On Spectrum-1 and Spectrum-2, this per-TC value is not available, and
zeroes will be reported, as they currently are.

Make the drivers which use single-byte netdev addresses
(netdev->addr_len == 1) use the appropriate address setting
helpers.
arcnet copies from int variables and io reads a lot, so
add a helper for arcnet drivers to use.
Similar helper could be reused for phonet and appletalk
but there isn't any good central location where we could
put it, and netdevice.h is already very crowded.

Commit a0c76345e3d3 ("devlink: disallow reload operation during device
cleanup") added devlink_reload_{enable,disable}() APIs to prevent reload
operation from racing with device probe/dismantle.
After recent changes to move devlink_register() to the end of device
probe and devlink_unregister() to the beginning of device dismantle,
these races can no longer happen. Reload operations will be denied if
the devlink instance is unregistered and devlink_unregister() will block
until all in-flight operations are done.
Therefore, remove these devlink_reload_{enable,disable}() APIs.

Introduce new devlink call to set feature mask to control devlink
behavior during device initialization phase after devlink_alloc()
is already called.
This allows us to set reload ops based on device property which
is not known at the beginning of driver initialization.
For the sake of simplicity, this API lacks any type of locking and
needs to be called before devlink_register() to make sure that no
parallel access to the ops is possible at this stage.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.
So, take the opportunity to refactor the hnae_handle structure to switch
the last member to flexible array, changing the code accordingly. Also,
fix the comment in the hnae_vf_cb structure to inform that the ae_handle
member must be the last member.
Then, use the struct_size() helper to do the arithmetic instead of the
argument "size + count * size" in the kzalloc() function.
This code was detected with the help of Coccinelle and audited and fixed
manually.

One block can be bound to several qevents. The qevent type that the block
is bound to determines which actions make sense in a given context. In the
particular case of mlxsw, trap cannot be offloaded on a RED mark qevent,
because the trap contract specifies that the packet is dropped in the HW
datapath, and the HW trigger that the action is offloaded to is always
forwarding the packet (in addition to marking in).
Therefore keep track of which actions are permissible at each binding
block. When an attempt is made to bind a certain action at a binding point
where it is not supported, bounce the request.
