Hi, Poborsky Please try sending an IP packet (not UDP, TCP or SCTP).
Or you can try to set filter.l4type = RTE_FDIR_L4TYPE_TCP when adding a filter. I guess it is because the NIC already classify you packet as TCP one. > -----Original Message----- > From: dev [mailto:dev-bounces at dpdk.org] On Behalf Of Newman Poborsky > Sent: Thursday, October 30, 2014 11:18 PM > To: dev at dpdk.org > Subject: [dpdk-dev] flow director - perfect match filter > > Hi, > > I'm not sure this is the right place to post a question like this, but I've > been > stuck with the same problem for days now. > > I'm trying to use flow director perfect match filters and so far I haven't > been > able to get it working.
