Description

Intel® Ethernet needs to be set to 5Gbps/2.5 Gbps.

Resolution

As of Release 25.4 of the Ethernet drivers, support for NBASE-T technology was modified to allow selection of 2.5Gb and 5Gb speeds.

When the user specifies 2.5G, this will configure the device for auto-negotiation with 2.5G as the only speed advertised.

When the user specifies 5G, this will configure the device for auto-negotiation with 5G as the only speed advertised.
