This patch ensures that the Maximum Payload Size (MPS) and Maximum Read Request Size (MRRS) settings of the root port associated with r8168 ethernet endpoint are properly configured after overwritten by kernel when pcie_bus_perf is enabled.

The RealTek drivers do not build against all Linux distributions because
some Linux distributions have back-ported upstream changes and so the
KERNEL_VERSION checks in the driver do not work for these distributions.
Add compilation flags for these drivers so that we can skip the building
of these drivers for certain Linux distributions.
Please note that the RealTek drivers build fine against Linux v5.14 and
so we should not prevent these driver being built against all Linux
v5.14 kernels.

The correct module license string for drivers is "GPL" and not "GPL
V2". Note that "GPL" in the module license indicates GPLv2 according to
the kernel documentation. Using "GPL V2" causes the following kernel
warns to be printed when the module is loaded ...
r8168: module license 'GPL V2' taints kernel.
Disabling lock debugging due to kernel taint
r8168: module license taints kernel.
Fix this by correcting the license string for dummy drivers.

During debugging it was found that enable/disable pll circuit

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.
A test has been added to the conftest script to detect the presence of
the ethtool_keee structure and so use the definitions generated by
conftest to compile the r8168 accordingly. Note that because the
'supported', 'advertised' and 'lp_advertised' fields are no longer 'u32'
types use the functions mii_eee_cap1_mod_linkmode_t() and
linkmode_to_mii_eee_cap1_t() for working with the bitmap types.

For Linux v6.8, the function strlcpy() has been removed. The function
strscpy() was added in Linux v4.3 and has been preferred over strlcpy().
See upstream Linux commit 30035e45753b ("string: provide strscpy()") for
more details. The Linux checkpatch.pl script warns against using
strlcpy().
The function strscpy() takes the same arguments as strlcpy(), but
returns a type of ssize_t instead of size_t. Update the drivers to use
strscpy() instead of strlcpy().

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.

Commit d457a0e329b0 ("net: move gso declarations and functions to their

updating the conftest Makefile to check for the presence of this header
file and use the definition generated by conftest accordingly in the

Instead of relying on kernel version to determine if functions or
specific versions of functions are present in the kernel, add compile
time tests to the conftest.sh script to determine this at compile time
for the kernel being used. This is beneficial for working with 3rd party
Linux kernels that may have back-ported upstream changes into their
kernel and so the kernel version checks do not work.

Upstream Linux kernel commit b48b89f9c189 ("net: drop the weight
argument from netif_napi_add") removes the weight argument from the
netif_napi_add() function and this is breaking the build of a few
drivers that use this function. Fix this by updating these drivers
to use the netif_napi_add_weight() function instead for Linux v6.1.
Finally, allow building the realtek wireless driver for kernels other
than v5.15 so that we can ensure it will build against other kernel
versions.
