Hmm, maybe we should just add a vls directory with sl0 ... sl15 or something like that in generic code? I don't see why this needs to be driver-specific code. > Yes, this is what I'm working on. > The patch is the only change outside of the hw/qib/ directory. > Do you want to see a preview of the sysfs code? I think the earlier you can post the whole driver, the sooner you'll get it upstream. - R. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
