Hello, Is it possible with ixgbe/82599 to use Flow Director to map traffic to particular 82599 queues and then use either PF_PACKET sockets or the PF_RING capability to busy-poll a thread on each queue?
Need to receive traffic from several different UDP ports together so the only solution I'm aware of is to read raw frames. Need to be able to have particular threads operate exclusively on particular queues. Have this working with Myricom DBL, but would be nice do accomplish it with 'ixgbe'. The goal, of course, is to read data without interrupts or context switches. ----- Does the newer Intel 10G silicon support ring queues larger than 65535 entries? If so one could use PF_RING to access the hardware directly while avoiding data loss from traffic bursts. That 16-bit ring limit in the 82599 is a killer. Thanks!
