files generated by text2pacp not suported

Hi

files generated from text2pcap not suppored

raises:
File "/usr/local/lib/python2.7/dist-packages/pcapng/structs.py", line 538, in _get_raw
raise KeyError(name)
KeyError: 'if_name'

Looks like they are missing a required field from a structure. Shouldn't be a big problem though to make it optional. Could you please provide me with a (small) sample of a file that causes the issue, so I can include it in the test suite?

Thanks
