Is it still possible to configure a 56 Gbps Ethernet link between two MCX354A-FCCT network cards? I also have two MC2207128-003 Mellannox 56Gbps Infiniband cables.
I found a guide that involved flashing custom firmware with 56Gbps link rates configured but the source code for the firmware has since been taken down. Now that the key to enable 56Gbps links on switches is free is it possible to enable this link rate without a switch?
