The 'adjfine' method was first introduced in Linux v4.10 by commit
d8d263541913 ("ptp: Introduce a high resolution frequency adjustment
method.") and the 'adjfreq' method was finally removed in Linux v6.2.
Given that 'adjfine' has been supported since Linux v4.10, drop the
deprecated 'adjfreq' method completely to simplify the nvethernet
driver. This fixes build issues for 3rd party kernels that removed the
'adjfreq' method and are older than Linux v6.2.

For Linux v6.9, the structure 'ethtool_eee' was replaced by
'ethtool_keee' and this new structure uses bitmaps for the structure
fields 'supported', 'advertised' and 'lp_advertised' as opposed to
'u32' types.
Add a test to conftest to detect the presence of the new 'ethtool_keee'
structure and update the nvethernet driver to use the various
linkmode_xxx helper functions for accessing the bitmap structure fields.

Existing implementation uses a single page_pool
for all Rx DMA channels. As by default all irqs
are on CPU 0, this does not cause any issue.
Routing an irq to some other CPU causes race
conditon for page allocation from page_pool which
leads to random memory corruption.

See upstream Linux commit 30035e45753b ("string: provide strscpy()") for

The compiler option -Wmissing-prototypes is being enabled globally in
the upstream Linux kernel and this causes build failures for various
drivers. The build failures occur because either the driver is missing
an include file which has the prototype or because the function is not
declared statically when it should be (ie. there are no external users).
Fix the various build failures and enable -Wmissing-prototypes to
prevent any new instances from occurring. Note that the only driver that
is not fixed at the moment is rtl8822ce due to large number of failures
and so build this with '-Wno-missing-prototypes' for now, which is not
different to how it was being compiled prior to this change.

The new Tegra Prod APIs are to be used for NVIDIA Linux kernels v5.16+.
Building the MTTCAN and QUAD SPI driver currently fail for upstream
Linux v5.16 because the various version definitions are not correct.
Some definitions have greater than v5.16.0 instead of greater than OR
equal to v5.16.0. This means that the new APIs will only be used
starting with v5.16.1+ and not v5.16.0 as inteaded.
Other definitions have less than or equal to v5.16.0 instead of just
less than v5.16.0. This means that we will still use the legacy APIs for
v5.16.0.
Fix this by correcting the definition that the drivers can be built for
upstream Linux v5.16.
