Ethernet technology on Qualcomm Linux supports the Energy Efficient Ethernet (EEE)
            feature.

### Energy Efficient Ethernet

EEE is an optional operational mode that helps in reducing the consumption of power
                while transmitting and receiving data. When there is no data to transmit or receive,
                this feature allows the MAC sublayer and a family of physical layers (PHY) to
                operate in the low-power idle (LPI) mode.

During link negotiation, the link partners learn about the capabilities and features,
                such as EEE, supported by the remote entity. Based on the supported capabilities,
                features, and data transfer state, the MAC determines whether the system should
                enter or exit the LPI mode and communicates it to the PHY.

The EEE feature specifies the capabilities and negotiation methods that the link
                partners can use to determine whether EEE is supported and then select the set of
                parameters that are common to both the devices.
