>
> Introduce the ICE_AQC_PORT_OPT_MAX_LANE_40G constant and update the code to process this new option in both the devlink and the Admin Queue Command GET PORT OPTION (opcode 0x06EA) message, similar to existing constants like ICE_AQC_PORT_OPT_MAX_LANE_50G, ICE_AQC_PORT_OPT_MAX_LANE_100G, and so on.

> This feature allows the driver to correctly report configuration options for 2x40G on ICX-D LCC and other cards in the future via devlink.
