Regular 5tuple filters don't have any stats similar to "fdirmatch"(in the rte_eth_stats 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 On Wed, Jan 14, 2015 at 5:27 AM, Bruce Richardson < bruce.richardson@intel.com> wrote: > On Tue, Jan 13, 2015 at 11:21:08PM -0500, Kamraan Nasim wrote: > > Hello, > > > > I've been using DPDK fdir filter APIs for 82599 NIC(Niantic) and they > work > > very well. > > > > Was wondering if I these could also be used for I210, 1Gbps NICs? > > > > The other option is to use 5tuple filters(rte_eth_dev_add_5tuple_filter > > < > http://dpdk.org/doc/api/rte__ethdev_8h.html#aaa28adafa65a4f47d4aeceaf1b08381b > >), > > however these do not support IPv6 yet. > > > > > > Have people in the community had any luck with configuring L3/L4 hardware > > filters for the I210 NIC? > > > > Thanks, > > Kam > > Flow director filters are not supported for 1G NICs.
