I have just set up my new gigabit network and when I was about to increase the MTU to use jumbo frames, I get this error:
root@rayquang-desktop:~# ifconfig eth1 mtu 9000 SIOCSIFMTU: Invalid argument
Could anyone help me to increase the MTU.
Details: NIC: NETGEAR GA311; Switch: NETGEAR GS105, running Ubuntu 10.10 and Debian Lenny on desktop, server respectively.
Help would be greatly appreciated, RayQuang
