The Marvell switches allow the hash algorithm for MAC addresses in the
address translation unit to be configured. Add support to the DSA core
to allow DSA drivers to make use of devlink parameters, and allow the
ATU hash to be get/set via such a parameter.
v2:
Pass a pointer for where the hash should be stored, return a plain
errno, or 0.
Document the parameter.
v3:
Document type of parameter, and valid range
Add break statements to default clause of switch
Directly use ctx->val.vu8
v4:
Consistently use devlink, not a mix of devlink and dl.
Fix allocation of devlink priv
Remove upper case from parameter name
Make mask 16 bit wide.

Add plumbing to allow DSA drivers to register parameters with devlink.
To keep with the abstraction, the DSA drivers pass the ds structure to
these helpers, and the DSA core then translates that to the devlink
structure associated to the device.

Some of the marvell switches have bits controlling the hash algorithm
the ATU uses for MAC addresses. In some industrial settings, where all
the devices are from the same manufacture, and hence use the same OUI,
the default hashing algorithm is not optimal. Allow the other
algorithms to be selected via devlink.

This is quite verbose. Can't you name this just "atu_hash" and be
aligned with the function names and MV88E6XXX_DEVLINK_PARAM_ID_ATU_HASH
and others?
Otherwise, the patch looks fine to me.

Hi Jiri
I would use ATU_hash, but not atu_hash, sorry.
Hopefully somebody will implement bash command completion, making it
easier.

That, I don't understand at all :/
The devlink param namespace is full of abbreviations. For example:
iwarp_cmt
gre_ver_check
enable_sriov
ignore_ari
msix_vec_per_pf_max
msix_vec_per_pf_min
fw_load_policy
reset_dev_on_drv_probe
acl_region_rehash_interval
enable_64b_cqe_eqe
enable_4k_uar
Why your thing is special?
Could you please follow the rest of the existing params?

Why are params special? Devlink resources can and do have upper case
characters. So we get into inconsistencies within devlink,
particularly if there is a link between a parameter and a resources.
And i will soon be adding a resource, and it will be upper case, since
that is allowed. And it will be related to the ATU.

Well, only for netdevsim. Spectrum*.c resources follow the same format.
I believe that the same format should apply on resources as well.

Plus reporters, dpipes follow the same format too. I'm going to send

Hi Jiri
I'm pretty much against this. This appears to be arbitrary. There is
no technical reason, other than most users so far have kept to lower
case. But in general, the kernel does not impose such restrictions.
Ethtool statistics are mixed case.
Interface names are mixed case.
/dev devices are mixed case.
Namespaces are mixed case.
All HWMON properties and names are mixed case.
Interrupt names are mixed case.
IIO names are mixed case.
etc.
Apart from the FAT filesystem, can you think of any places in the
kernel which enforce lower case? And if so, why does it impose lower
case?
Andrew
