[ Upstream commitbba25915b1] The 'phy-mode' property is currently defined as 'rgmii' for Jetson Xavier. This indicates that the RGMII RX and TX delays are set by the MAC and the internal delays set by the PHY are not used. If the Marvell PHY driver is enabled, such that it is used and not the generic PHY, ethernet failures are seen (DHCP is failing to obtain an IP address) and this is caused because the Marvell PHY driver is disabling the internal RX and TX delays. For Jetson Xavier the internal PHY RX and TX delay should be used and so fix this by setting the 'phy-mode' to 'rgmii-id' and not 'rgmii'.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
