I have
Netgear GA311 ethernet card. I am wondering how to enable jumbo packets.
I do:
bash-3.00# ifconfig eth0 mtu 9014
bash: SIOCSIFMTU:: command not found
Am I doing something wrong? I am fairly certain the GA311 is able to do jumbo packets. I know my switch does(Netgear GS108.) It works on dummy0 but not on eth0.
ifconfig -a reveals:
dummy0 Link encap:Ethernet HWaddr <insert mac address here>

If that is of any use to anyone.
I can get it to do 7200 mtu. I didn't think to lower the amount. Maybe I'll have to pick another intel card, since it seems it can do 16436 as I have it in my other machine.
