I have modified the l2fwd example application provided with dpdk in order t= o benefit from RSS. I have a development machine with an Intel I350 NIC (1G= b) where RSS seem to work (traffic forwarded on all cores). On the test machine there is a 82598EB based network card and here the RSS = doesn't work, only core 0 is forwarding traffic. Looking into ixgbe_dev_mq_rx_configure() function from dpdk lib I can see t= hat for this type of network controller the configuring function exits imme= diately. i.e. if (hw->mac.type =3D=3D ixgbe_mac_82598EB) return 0; However the datasheet claims that RSS is supported. The test machine is an Intel Xeon E5420 @ 2.50GHz. Does anyone have an idea about why RSS would not work in the 82598EB case? Thanks, Costin
