Dynamic power management of ethernet interface

A receiving network device, comprising:

• a Serializer/Deserializer (SerDes) receiver configured to receive data from a transmitting network device;
• a media access control receiver coupled to the SerDes receiver;
• and
• a power management logic configured to:
• determine that the received data corresponds to one of a last valid transaction or a first valid transaction;
• and
• transmit one or more control indications to the media access control receiver based on the received data corresponding to the one of the last valid transaction or the first valid transaction, wherein, based on the one or more control indications, the media access control receiver is configured to transition from a first power mode to a second power mode.

A method, comprising:

• determining absence of pending data for processing;
• completing transmission of residual processed data of an ongoing data transfer operation based on the determined absence of the pending data for the processing;
• and
• transmitting one or more control indications to a Serializer/Deserializer (SerDes) transmitter based on the completion of the transmission of the residual processed data, wherein
• the SerDes transmitter is configured to transition from a power-up mode to a power-down mode based on the one or more control indications.
