Thanks Hal, we indeed do. And we would like to continue to do so, be it by setting a flag or otherwise. I hope removing that functionality from the kernel is not an option, as it would be a major inconvenience for us. Thanks, Suri

There are 2 vendors that I'm aware of that use linux for their embedded IB switch platforms: Mellanox and Bay Microsystems and there may be others.
