How do I configure my IG nic to use jumbo frames? Neither ifconfig nor ip work for me.
Does your NIC support jumbo frames?
The usual way to configure it seems to be "ifconfig ethX mtu 9000".

This command worked on Fedora 9, but not on suse. f9: MSI K9N NEO motherboard with 1G nic SUSE MSI K9N NEO V3 motherboard with 1G nic
The error I get (when jumbos aren't supported by the NIC) is "SIOCSIFMTU invalid argument". Any chance you have different version of drivers on Fedora/openSUSE?
I get two different errors on OpenBSD and Suse 'mtu X' gives invalid argument. 'mtu=X' gives invalid value.
That command also failed on OpenBSD which seems to want 'mtu=X' instead of 'mtu X'. 1G Nic is Netgear 311.
And it does actually run with jumbo frames - did you test it?
I don't know how to test if jumbo frames work. F9 took an mtu 9000 command.
