in order to perform compliance tests of our product, we would need to send a test-pattern from the ethernet interface. For this, I need to set registers on the phy.
In L4T R28.2, ethtool says that it is not supported to read/write the registers.
In the u-boot shell the phy is not loaded yet, so it can’t be done either.
How does one normally enable a test-pattern for compliance tests?
