net: macb: Adding Support for Jumbo Frames up to 10240 Bytes in SAMA5D3
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.
