On the LS1021A-TSN board, the 2 Atheros AR8031 PHYs for eth0 and eth1 have interrupt lines connected to the shared IRQ2_B LS1021A pin. Switching to interrupts offloads the PHY library from the task of polling the MDIO status and AN registers (1, 4, 5) every second. Unfortunately, the BCM5464R quad PHY connected to the switch does not appear to have an interrupt line routed to the SoC.

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.
