Thanks Joel for the careful review. The MDIO controller is not paired
with BMC MAC; instead, it's connected to the MDC/MDIO interface of the
on-board switch (whose ports are connected to BMC, Host and front panel
management port).
In other word, the MDIO controller is used, but we do need some user
space scripts to control the controller. What's your suggestion? For
example, should I add some comments to explain the purpose?
Cheers,
Tao
