[Question] RK3288 (Tinkerboard) maximum ethernet MTU #20

Closed rfrht closed 6 years ago

rfrht commented 6 years ago

Hi there Rockchip / Maintainers;

What is the maximum supported MTU for RK3288 Gigabit Ethernet interface?

Trying to change MTU results a error here [using 4.4.120-beleza8-rockchip (Beleza8 is my build) from Armbian]:

root@tinkerboard:~# ifconfig eth0 mtu 8000
SIOCSIFMTU: Device or resource busy

Thanks a lot,
