From: vishnuvardhan <vardhanraj4...@gmail.com> As per the SAMA5D3 device specification it supports Jumbo frames. 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.
