Roger Quadros 49a2eb9068 net: ethernet: ti: am65-cpsw-qos: Add Frame Preemption MAC Merge support
Add driver support for viewing / changing the MAC Merge sublayer
parameters and seeing the verification state machine's current state
via ethtool.

As hardware does not support interrupt notification for verification
events we resort to polling on link up. On link up we try a couple of
times for verification success and if unsuccessful then give up.

The Frame Preemption feature is described in the Technical Reference
Manual [1] in section:
	12.3.1.4.6.7 Intersperced Express Traffic (IET – P802.3br/D2.0)

Due to Silicon Errata i2208 [2] we set limit min IET fragment size to
124 (excluding 4 bytes mCRC).

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.
