Hi There Does Wireshark/WinPCAP capture and show the checksum offload info from the out-of-band data? Thanks Arun asked 12 Oct '10, 10:22  Arun |
One Answer:
I'm going to guess a big No on this one. Dropped packet stats may be recorded by the driver somewhere - but those communications are probably not seen by wireshark. Its kind of against the point to have an offloading NIC report back to the CPU when it drops a packet... answered 13 Oct '10, 11:01  GeonJay |
Hi Arun - can you be a bit more specific regarding which out-of-band data you are interested in? If the out-of-band data is carried in a packet and it is passed up to Wireshark, then you should be able to see it. There is some out-of-band data that does not actually cross the network, but is used between a driver and protocol stack, hence the question for clarification.
Hi
Thanks for the quick response. Sorry I should have been more clear. This is about the out-of-band data used between NIC driver and protocol stack. Specifically I want to find out if a Checksum offloading adapter/driver said good checksum or bad checksum for an incoming packet.
Thanks Arun
