The document provides instructions for enabling and configuring a 40GbE network interface card (NIC) on a Vyatta Core 6.5 R1 system. It includes steps to load the necessary kernel modules, check the status and settings of the NIC, and verify options and modules. The summaries also provide brief output from commands to check the NIC driver version, bus information, offload parameters, and module details.
