DEPRECATED: Updated Linux drivers for the ATWILC1000/ATWILC3000 products are located at https://github.com/linux4microchip/linux/tree/master/drivers/net/wireless/microchip/wilc1000. To simplify development, the legacy Linux4WILC was merged into the Linux4Microchip repo where driver development continues (Please refer latest ATWILC1000/ATWILC 3000 Wi-Fi Link Controller Linux User Guide) Driver code for Microchip ATWILC Wireless Devices (ATWILC1000 & ATWILC3000)

Allow MTU to be set greater than 1500bytes #106

Driver code does not set ndev->max_mtu, so defaults to 1500 bytes. Wifi will carry packets with larger size, and this is useful when using another protocol to tunnel, while not needing to fragment large IP frames.

The following diff shows a tested & working example, however the max size should be set to a value that is tested to work with the WILC firmware.
