ix(4): Add EEE support for E610 adapters

2026-03-27T11:43:22Z

The ix driver now supports Energy Efficient Ethernet (EEE) on Intel E610 devices. EEE allows the network interface to enter low-power states during periods of low link utilization, reducing power consumption while maintaining full performance when needed. E610 adapters provide EEE support through BASE-T PHY functionality. Due to this PHY-based implementation, EEE is supported only on 2.5Gb speeds and above.
