Hello, This mail might belong to the discuss mailing list but since this is regarding feature currently under dev i figure this will be the best place.
I am trying to install OVS with dpdk 1.8.0 support on a system with Mellanox NIC (ConnectX-3 Pro, dpdk works with no issues). Everything works as expected (i hope.. except minor change in the code i had to do due to fact that ETH_RSS_TCP is not in dpdk 1.8.0) until the stage i'm adding the dpdk0 port to br0. I get the following error: # ovs-vsctl add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk ovs-vsctl: Error detected while setting up 'dpdk0'. See ovs-vswitchd log for details. And in the logs: ovs-vswitchd[25530]: ovs|00021|bridge|WARN|could not open network device dpdk0 (No such device) It seems like the dpdk0 can't be created. How does ovs assign the dpdkX to physical port? is there some parameter i can pass? any chance it has some Intel specific code? Any ideas what prevent it from being created? There is a good chance i am missing something very basic so if this is the case sorry in advance for that! thanks in advance!
