Configuring FCoE Hardware Offload

You can use the tunables listed in Table 7-1 to reduce CPU utilization and improve performance on a system with FCoE ports. These tunables are supported by the Intel 10 Gb Ethernet devices and set in the ixgbe.conf file.

Copy the /kernel/drv/ixgbe.conf to /etc/driver/drv/ixgbe.conf and modify the tunable values for your FCoE environment.
