Looks good. A couple caveats about debugfs. 1) Don't use it for API's not available elsewhere. You don't want it to become a stable API which other tools get tied too. 2) Best to make it an optional config option (dependent on DEBUGFS) that way it is possible to have rocker support w/o having DEBUGF configured. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
