Nope, the fact that it's messed up is what I was trying to point out.
From a quick look at the code, it looks like you should set the
environment variable VIADEV_DEFAULT_MTU to "MTU1024" on PCI-X systems
and "MTU2048" on PCI Express systems.
In general, one wants to use the largest possible MTU to get maximum
performance.
Yes, I was not sure if IA64 should be 2048 or 1024 when I proposed the patch.
If I get time I will try and test our which is best fo IA64.
