Shenwei Wang ec2a1681ed net: fec: use a member variable for maximum buffer size
Refactor code to support Jumbo frame functionality by adding a member
variable in the fec_enet_private structure to store PKT_MAXBUF_SIZE.

Remove the OPT_FRAME_SIZE and define a new macro OPT_ARCH_HAS_MAX_FL to
indicate architectures that support configurable maximum frame length.
And update the MAX_FL register value to max_buf_size when
OPT_ARCH_HAS_MAX_FL is defined as 1.

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.
