Some device names were wrong because our internal data suggested
that discrete Ga devices have B-step RF, when they actually have
C-step. However, matching the step for them is bad anyway.
Change the code to be able to find the devinfo depending on the
device being integrated or discrete. This is only for the names,
since the RF config cannot be different for the same RF because
it's discrete or integrated, so add a kunit test that ensures
both (a) the RF config is the same and (b) the name is different
(the latter really only because that's the whole point of having
a match on the discrete/integrated bit.)
Remove the RF step matching since it's no longer needed now.

We needed it for setting up trans parameters that could change later in
the probe flow.
This is no longer true, now we know all the parameters before we allocate the
trans, so we can just send the right parameters to iwl_trans_alloc and have all

Given compatibility issues with external PNVM data that doesn't match
the firmware it was designed with/for, future firmware releases will
include the PNVM data in the firmware files directly, avoiding those
mismatch issues. Make the driver load and use that embedded PNVM data
in preference of external files, falling back to the external file if
it isn't present.

fbnic_fw_clear_cmpl() does the inverse of fbnic_mbx_set_cmpl().
It removes the completion from the mailbox table.
It also calls fbnic_mbx_set_cmpl_slot() internally.
It should have fbnic_mbx prefix, not fbnic_fw.
I'm not very clear on what the distinction is between the two
prefixes but the matching "set" and "clear" functions should
use the same prefix.
While at it move the "clear" function closer to the "set".

Follow-up to RGMII mode clarification: am65-cpsw fix + checkpatch
Following previous discussion [1] and the documentation update by
Andrew [2]:
Fix up the mode to account for the fixed TX delay on the AM65 CPSW
Ethernet controllers, similar to the way the icssg-prueth does it. For
backwards compatibility, the "impossible" modes that claim to have a
delay on the PCB are still accepted, but trigger a warning message.
As Andrew suggested, I have also added a checkpatch check that requires
a comment for any RGMII mode that is not "rgmii-id".
No Device Trees are updated to avoid the warning for now, to give other
projects syncing the Linux Device Trees some time to fix their drivers
as well. I intend to submit an equivalent change for U-Boot's
am65-cpsw-nuss driver as soon as the changes are accepted for Linux.

Historically, the RGMII PHY modes specified in Device Trees have been
used inconsistently, often referring to the usage of delays on the PHY
side rather than describing the board; many drivers still implement this
incorrectly.
Require a comment in Devices Trees using these modes (usually mentioning
that the delay is realized on the PCB), so we can avoid adding more
incorrect uses (or will at least notice which drivers still need to be
fixed).

netlink: specs: enforce strict naming of properties
I got annoyed once again by the name properties in the ethtool spec
which use underscore instead of dash. I previously assumed that there
is a lot of such properties in the specs so fixing them now would
be near impossible. On a closer look, however, I only found 22
(rough grep suggests we have ~4.8k names in the specs, so bad ones
are just 0.46%).
Add a regex to the JSON schema to enforce the naming, fix the few
bad names. I was hoping we could start enforcing this from newer
families, but there's no correlation between the protocol and the
number of errors. If anything classic netlink has more recently
added specs so it has fewer errors.
The regex is just for name properties which will end up visible
to the user (in Python or YNL CLI). I left the c-name properties
alone, those don't matter as much. C codegen rewrites them, anyway.
I'm not updating the spec for genetlink-c. Looks like it has no
users, new families use genetlink, all old ones need genetlink-legacy.
If these patches are merged I will remove genetlink-c completely
in net-next.

Add a regexp to make sure all names which may end up being visible
to the user consist of lower case characters, numbers and dashes.
Underscores keep sneaking into the specs, which is not visible
in the C code but makes the Python and alike inconsistent.
Note that starting with a number is okay, as in C the full
name will include the family name.
For legacy families we can't enforce the naming in the family
name or the multicast group names, as these are part of the
binary uAPI of the kernel.
For classic netlink we need to allow capital letters in names
of struct members. TC has some structs with capitalized members.

enetc_hw.h provides two versions of _enetc_rd_reg64.
One which simply calls ioread64() when available.
And another that composes the 64-bit result from ioread32() calls.
In the second case the code appears to assume that each ioread32() call
returns a little-endian value. However both the shift and logical or
used to compose the return value would not work correctly on big endian
systems if this were the case. Moreover, this is inconsistent with the
first case where the return value of ioread64() is assumed to be in host
byte order.
It appears that the correct approach is for both versions to treat the
return value of ioread*() functions as being in host byte order. And
this patch corrects the ioread32()-based version to do so.
This is a bug but would only manifest on big endian systems
that make use of the ioread32-based implementation of _enetc_rd_reg64.
While all in-tree users of this driver are little endian and
make use of the ioread64-based implementation of _enetc_rd_reg64.
Thus, no in-tree user of this driver is affected by this bug.
