ixgbe DMA question

[Santosh Rao Gururajan]

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,
