Hmm, what if the application is sth. like a MPEG demultiplexer? There you don't like to look at everything and excplicitly ignore received data[1]. Yes, I know this is usually done with hardware demuxers and filters, but the principle might apply to other applications as well, for which no hardware solutions exist. Regards Ingo Oeser [1] which you cannot ignore properly with Linux yet. - 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
