dissect_ip() and check for header length

Hi, I'm evaluating the way how to add support into Wireshark for Solaris snoop files with IP tunnel links data. The data are basically RAW IP so I wouldn't have to write new dissector. But the problem is that stored packets for *outgoing* traffic doesn't contain "Header length" (it's zero as at layer where it was captured it wasn't filled, the same case is for "Header checksum"). dissect_ip() for such packets will report just: "Header length: %u bytes (bogus, must be at least %u)". So we can either lighten this condition in dissect_ip() and continue with the packet processing (e.g if length and check sum is zero). Or I can create new dissector which will just add correct header length and pass it along to dissect_ip(). Thanks for any comments/suggestions.
