dpdk-devbind.py can also be used to bind devices to kernel modules. Some kernel modules are registered with '-' in their name and are populated with '-' in '/sys/bus/pci/drivers/' but kernel populates the name in /sys/modules/ as '_' This confuses the current script making it unable to bind to such modules. The patch addresses it by always replacing '-' with '_' when looking in /sys/modules/ Hope this clears things up. Pavan.
