Hence, for = a 5-tuple flow, packet in one direction can be routed to a queue that = may be different than packet in the other direction. I=92m wondering if = there is a configuration or mechanism to get a symmetric hash so that = all packets for a given flow will be in the same queue. Thanks in = advance.=20 Dan=
