enic: Support newer version of firmware devcmd CMD_MCPU_FW_INFO
This patch provides support to the newer version of firmware devcmd CMD_MCPU_FW_INFO that returns additional information (ASIC type and revision) about the underlying hardware. This knowledge is required by the driver to implement any hardware specific features.
