Energy efficient Ethernet
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 this information to the PHY.The EEE feature specifies the capabilities and negotiation methods that the link partners can use to:
- Determine whether EEE is supported.
- Select the set of parameters that are common to both the devices.
EEE feature is supported only on QEP8121 PHY.

Device tree source overlay (QPS615)
A Device tree source (DTS) overlay is a modular extension to a Linux device tree that allows hardware descriptions to be added, modified, or enabled on top of an existing base device tree.DTS overlays are typically applied at boot time and allow hardware configuration changes without modifying or recompiling the original device tree. This mechanism is commonly used to enable optional peripherals or board-specific features.EFI based overlay is required to enable Ethernet interfaces, which in turn enable XO shutdown and S2R functionality.
