The IDataLink.Kind property returns an Enum value for the datalink when it can translate it to one (otherwise it throws an exception).

The RAW datalink Kind is DataLinkKind.IpV4.

If the packet was received, you can probably down cast the IDataLink instance you have to PcapDataLink and use either the PcapDataLink.Name property or the PcapDataLink.Value property to get the string or integer value for the datalink.

If you have packets with datalinks that don't have a Kind value, you're welcome to provide .pcap samples for them in Pcap.Net Q&A group so I can add support for them.
