The ks8851 chip is sold either with an SPI interface (KSZ8851SNL) or
with a so-called non-PCI interface (KSZ8851-16MLL). When the driver
for the latter was introduced with commit a55c0a0ed415 ("drivers/net:
ks8851_mll ethernet network driver"), it duplicated the register macros
introduced by the driver for the former with commit 3ba81f3ece3c ("net:
Micrel KS8851 SPI network driver").
The chips are almost identical, so the duplication seems unwarranted.
There are a handful of bits which are in use on the KSZ8851-16MLL but
reserved on the KSZ8851SNL, and vice-versa, but there are no actual
collisions.
Thus, remove the duplicate definitions from the KSZ8851-16MLL driver.
Mark all bits which differ between the two chips. Move the SPI frame
opcodes, which are specific to KSZ8851SNL, to its driver.
The KSZ8851-16MLL driver added a RXFCTR_THRESHOLD_MASK macro which is a
duplication of the RXFCTR_RXFCT_MASK macro, rename it where it's used.
Same for P1MBCR_FORCE_FDX, which duplicates the BMCR_FULLDPLX macro and
OBCR_ODS_16MA, which duplicates OBCR_ODS_16mA.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
