I have been using it recently and find it very very fast and efficient. However off late I am trying to capture Jumbo packets on the network for the following scenario's but that doesn't seem to be working. Please suggest in its present form is NetMap capable of handling the below scenario's w.r.t Jumbo frames? If how do we have to some special handling w.r.t to this? 1) Netmap is receiving un-fragmented Jumbo frame. In this case is NetMap capable of passing on the Jumbo packet to the user? 2) Netmap receving fragmented Jumbo frames. In this case is NetMap capable of reassembling the fragmented packets and deliver the assembled packet to the user? I have been stuck with this issue for some time now. A quick response would help a great deal. Thanks, Soumya Panigrahi
