I have a host machine with 2 ixgbe NICs. I am trying to pass the frames from one NIC to the other with the lowest possible overhead to the host (high speed bridge). I am wondering if I can do a rx-ring to tx-ring DMA copy without creating a mbuf on the host. Is that possible? What are the risks? Thanks, -santosh
