Originally the type of path_ok is bool to denote that DPK is ready on
certain path and can be enabled. For RTL8851B, hardware design can support
more than one calibration set, so use type u8 instead to record the
hardware set in current use.

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".

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.

We're trying to add a strict regexp for the name format in the spec.
Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen, if used, replaces special
chars in names) but it gives more uniform naming in Python.

Commit 4ea7e38696 ("dropmon: add ability to detect when hardware
drops rx packets") introduced is_drop_point_hw, but the symbol was
never referenced anywhere in the kernel tree and is currently not used
by dropwatch. I could not find, to the best of my abilities, a current
out-of-tree user of this macro.
The definition also contains a syntax error in its for-loop, so any
project that tried to compile against it would fail. Removing the
macro therefore eliminates dead code without breaking existing
users.

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.
Flagged by Sparse.
Compile tested only.
