The function mcp251xfd_chip_wait_for_osc_ready() polls the Oscillator
Control Register for the oscillator to get ready.
This is the first register the driver reads from. Reading implausible
values (all bits set or unset) can be caused by the chip starting up
after power on, waking up after sleep, or by the chip not being preset
at all. Add check for implausible register content
mcp251xfd_reg_invalid() to the regmap_read_poll_timeout() loop.
In case of a regmap_read_poll_timeout() returns a fatal error (and not
a timeout), forward it to the caller.
As mcp251xfd_chip_wait_for_osc_ready() will be called after the probe
function has finished, (currently during ifup), move error message
about failed chip detection from there into the probe function.

The mcp251xfd_chip_stop() function tries the best to stop the chip and
put it into sleep mode. It continues, even if some intermediate steps
fail. As none of the callers use the return value, let this function
return void.

The mcp251xfd driver supports runtime PM enabled kernels, but also
works on !CONFIG_PM configurations.
This patch simplifies the runtime PM handling in the
mcp251xfd_unregister(). In the CONFIG_PM case, runtime PM has been
enabled in the mcp251xfd_probe() function, so we can disable it here.
For !CONFIG_PM builds call mcp251xfd_clks_and_vdd_disable() directly.

MCP251XFD_REG_OSC is the first register the driver reads from. The
chip may be in deep sleep and the SPI transfer (i.e. the assertion of
the CS) will wake the chip up. This takes about 3ms. The CRC of this
transfer is wrong, or there isn't any chip at all, in this case the
CRC will be wrong, too. The driver ignores the CRC error and returns
the read data to the caller.
To avoid any confusion, this patch changes the
mcp251xfd_regmap_crc_read() function to only ignore the CRC error if
solely the OSC register is read. So when reading more than the OSC
registers at once, CRC errors are not ignored.

====================
Add ethtool support for completion queue event size
After a packet is sent or received by NIC then NIC posts
a completion queue event which consists of transmission status
(like send success or error) and received status(like
pointers to packet fragments). These completion events may
also use a ring similar to rx and tx rings. This patchset
introduces cqe-size ethtool parameter to modify the size
of the completion queue event if NIC hardware has that capability.
A bigger completion queue event can have more receive buffer pointers
inturn NIC can transfer a bigger frame from wire as long as
hardware(MAC) receive frame size limit is not exceeded.
Patch 1 adds support setting/getting cqe-size via
ethtool -G and ethtool -g.
Patch 2 includes octeontx2 driver changes to use
completion queue event size set from ethtool -G.

The OSM and EPSS hardware controls the frequency of each cluster in the
system based on requests from the OS and various limiting factors, such
as input from LMH.
In most systems the vote from the OS is done using a single register per
cluster, but some systems are configured to instead take one request per
core. In this configuration a set of consecutive registers are used for
the OS to request the frequency of each of the cores within the cluster.
The information is then aggregated in the hardware and the frequency for
the cluster is determined.
As the current implementation ends up only requesting a frequency for
the first core in each cluster and only the vote of non-idle cores are
considered it's often the case that the cluster will be clocked (much)
lower than expected.
It's possible that there are benefits of performing the per-core
requests from the OS, but more investigation of the outcome is needed
before introducing such support. As such this patch extends the request
for the cluster to be written to all the cores.
The weight of the policy's related_cpus is used to determine how many
cores, and hence consecutive registers, each cluster has.
The OS is not permitted to disable the per-core dcvs feature.
