When we are using a dedicated PHY driver (not the Generic PHY driver) chances are that it is going to configure RGMII delays and do that in a way that is incompatible with our incorrect interpretation of the phy_interface value. Add a quirk in order to reverse the PHY_INTERFACE_MODE_RGMII to the value of PHY_INTERFACE_MODE_RGMII_ID such that the MAC continues to be configured the way it used to be, but the PHY driver can account for adding delays. Conversely when PHY_INTERFACE_MODE_RGMII_TXID is specified, return PHY_INTERFACE_MODE_RGMII_RXID to the PHY since we will have enabled a TXC MAC delay (id_mode_dis=0, meaning there is a delay inserted). This is not considered a bug fix at this point since it only affects Broadcom STB platforms shipping with a Device Tree blob that is not updatable in the field (quite a few devices out there) and which was generated using the scripted Device Tree environment shipped with those platforms' SDK.

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.
