USXGMII specification clarification for Auto Negotiation

Hi there,

I would like to get some clarification for the "Universal SXGMII Interface for a Single MultiGigabit Copper Network Port" specification.

 

For the Table 2 in the specification, how does MAC knows the value to send to PHY? Does MAC need to pass back the speed and duplex information obtained from PHY?

 

What is the equation to resolve the speed after AN is completed? Always resolved to lowest speed support by both MAC and PHY?

 

Thanks.
