But the suggested flag and length of bytes it supports was not updated in this driver config_structure. The maximum jumbo frames the device supports: 10240 bytes as per the device spec. While changing the MTU value greater than 1500, it threw error: sudo ifconfig eth1 mtu 9000 SIOCSIFMTU: Invalid argument Add this support to driver so that it works as expected and designed.
