Can you explain the meanings of the 'phytool print' output and how to modify these parameters. This is more friendly to our beginners

Phytool is a low-level debug utility for those rare times when you need raw register access. If you want something more user-friendly, ethtool might be what you're looking for.

If you want to know more about the meaning of the register bits, I suggest you consult the datasheet for you specific PHY. If you don't have a datasheet available, many registers are standardized in IEEE 802.3 (Clause 22.2.4) which is available through IEEE's GET program: https://standards.ieee.org/products-programs/ieee-get-program/
