A couple years ago, we identified a performance problem in IPv6 because it had the index and not the dev in a per-packet piece of code. The result was spending a lot of time searching the device list just to increment a (required) per-device MIB counter. I don't know if that's still there or not, but of course those sorts of implications should be considered, too. +-DLS - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
