Configuring FCoE Hardware Offload
You can use the tunables listed in the following table 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 can be set in the
ixgbe.conf file.
Copy the /kernel/drv/ixgbe.conf file to
/etc/driver/drv/ixgbe.conf file, and
modify the tunable values for your FCoE environment.
