[gentoo-user] SIOCSIFMTU: Invalid argument

[Valmor de Almeida]

Hello,

I am getting a

SIOCSIFMTU: Invalid argument [ok]

message when re/starting eth0. I am wondering about that. The router's
MTU is set at 1500. Looking at the /etc/init.d/net.eth0 it seems the
inteface metrics should be calculated automatically.

Any ideas about where to look for the reason for the message? Additional
info below.

Thanks,
