What about the bonding drivers that Linux already has? I tried this guy once and failed miserably (it failed actually). Or how about the TEQL scheduler. (Haven't had a chance to try it yet.)

Doesn't really solve the same problem, Adam. You're still limited to the maximum bandwith of a single adapter; equal-cost routing and the other layer 3 solutions just decide which one to use. Etherchannel support allows you to bind the adapters in such a way that they appear to be a single layer 2 entity with a bandwidth equal to the sum of the bandwidth of the individual adapters. It's nice. Given the low physical density of S390 network adapters, this would be a Very Good Thing, at least until 10 Gbit Ethernet is widely available. Now that the qeth and QDIO drivers are open-source, we might be able to do something about the lack of Etherchannel support. I'll have a look later this evening.
