Please help me out. I have configured NTUPLE filter in my application with just Destination IP every thing else(SRC IP, S_PORT, D_PORT & proto) is disabled. But whenever i send packet from any machine, it means Different Source IP, hash value at DPDK app side changed and hence result in, Arrival of packet at different queue. Any hint would be appreciated. Thanks -- Rgds, NV ^ permalink raw reply [flat|nested] 6+ messages in thread

Suppose you're using 5-tuple, right? Suppose you're using a igb or ixgbe NIC as 5-tuple is only supported by igb/ixgbe, right? Would you like to let us know what you've done? I mean how you disable the other things. I think you might set the mask to do that. And please aware if the mask is FF, means the field is used.

I don’t find anything wrong in your code, except I’m not sure if the mask for dst_ip is right. Suppose it’s right ☺ Seems having to check if the register is right. I mean the registers in the function ixgbe_add_5tuple_filter. Not sure if it’s easy to check them in your APP. If not, maybe you can try testpmd first.
