The MBIM firmware for the Sierra Wireless MC7710 is a nice source of "interesting" device issues. One of the uglier ones is that it under certain conditions will start flooding us with frames having length 0 as fast as it can. And that is pretty fast...If you can tell that those frames are bogus, why not count them as opposed to generic qlen? Say, if you see 20 among the last 30 are of this type, throttle.
Sounds like a good idea, but where do I add/get that statistics? Bjørn -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
