Hi

Is it possible for ethereal to be configured to start decodeing from
acertain offset in a packet.

I am looking at an issue where the MAC layer is corrupt but the IP
information is vaild.
I would like to decode IP starting at offset 0x10

This is on a ethernet network.

    Time delta from previous packet: 0.000000 seconds
    Time relative to first packet: 0.000000 seconds
