Thanks Bruce, that's exactly it. Basically each filter will forward traffic to a unique RSS queue which can allow me to calculate filter match statistics for that queue(or filter). At that point I would like to drop the filtered packet. Is there any way to drop the filtered packet in the RSS queue without doing a rte_eth_rx_burst() and dropping it then? --Kam On Thu, Jan 15, 2015 at 9:44 AM, Bruce Richardson < bruce.richardson at intel.com> wrote: > On Wed, Jan 14, 2015 at 04:59:17PM -0500, Kamraan Nasim wrote: > > Many thanks Helin and Bruce :) > > > > Now if 1Gb NICs don't support fdir filters then im wondering how would we > > count the number of packets matching a filter. > > > > Regular 5tuple filters don't have any stats similar to "fdirmatch"(in the > > rte_eth_stats <http://dpdk.org/doc/api/structrte__eth__stats.html> > struct). > > One way I can think of is to use regular ibytes/ipackets stats for the > > queue to which the packets are being redirected in the 5tuple filter but > > this seems a bit hacky + there is no way to distinguish this packet > > throughput from the regular traffic that the NIC is forwarding to that > > specific queue. > > > > Is there a way to EXCLUSIVELY bind a 5tuple filter to an RSS queue so > that > > only matched traffic is forwarded there? > > > > > > --Kam > > > > What you can do is use a 5-tuple filter to send traffic to a queue.
