pcap_io: Only check byteswapped linktype if pcap magic is swapped
In pcap_validate_header() the linktype and the byte-swapped linktype are currently checked against the supported linktypes. Since the swapped linktype is always larger than LINKTYPE_MAX, only one of the two tests was actually done. Make this intention a bit more clear by explicitly checking only for either the swapped or non-swapped linktype, depending on whether the pcap magic is swapped. Also make the error messages a bit more verbose regarding the major/minor version. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
