You can set default_mtu in /kernel/drv/ixgbe.conf to enable jumbo frame. Please remember to rem_drv/add_drv or update_drv to make it to become effective. Currently we are working on adding/enabling/tuning more features (such as LSO/TSO, multiple rings, etc) which will eventually increase the performance greatly. Stay tuned.
