[PATCHv3 net-next 0/3] Add YNL test framework and library improvements

[Hangbin Liu <liuhangbin@gmail.com>]

This series enhances YNL tools with some functionalities and adds
YNL test framework.

Changes include:
- Add MAC address parsing support in YNL library
- Support ipv4-or-v6 display hint for dual-stack fields
- Add tests covering CLI and ethtool functionality

The tests provide usage examples and regression testing for YNL tools.
