bnx2x: Add support for single-port DCBx
Driver is currently looking at shared information for determining whether DCBx can be supported for a given port. On 4-port devices, up-to-date management firmware can support DCBx on each port of a given engine independently - but that would cause bnx2x to misinterpert the support and assume DCBx is supported on both.
