What is the effect of this on RoCE and IWARP adapters ? While they populate node_desc in sysfs, I don't think they support IB_DEVICE_MODIFY_NODE_DESC for ib_modify_device. Shouldn't such devices be "skipped" in terms of setting NodeDescription ? -- Hal > This deamon is intended to work with kernels which support polling of the > procfs hostname file.
