Wei Fang 2d33dc6058 net: fec: add more macros for bits of FEC_ECR
There are also some RCR bits that are not defined but are used by the
driver, so add macro definitions for these bits to improve readability
and maintainability.

In addition, although FEC_RCR_HALFDPX has been defined, it is not used
in the driver. According to the description of FEC_RCR[1] in RM, it is
used to disable receive on transmit. Therefore, it is more appropriate
to redefine FEC_RCR[1] as FEC_RCR_DRT.

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 reStructuredText 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.
