Need to know if I210 support 802.3az (EEE) when it is used with NC-SI interface.
From I210 datasheet, it says I210 supports 802.3az(EEE), but it doesn't say in which scenario. From the context it sounds I210 only support 802.3az(EEE) when it is connected to the host CPU with PCI-E interface.
802.3az define EEE which need Ethernet Physical Coding Sublayer (PCS)/ Physical Medium Attachment Sublayer (PMA)/ Physical Medium Dependent Sublayer (PMD) to implement the related function. NC-SI is Reduced media-independent interface (RMII) which have no related with EEE circuit. So NC-SI have no EEE function.
