Until v1.2.2, Sniffnet only supported parsing Ethernet packets.

With #421 support for interfaces based on raw IP and null/loopback was added to Sniffnet, covering the vast majority of possible use cases and scenarios.

This issue is intended to track the necessity to add support for even more link types.

The most important scenario that's still unsupported is, for example, parsing packets from the any interface on Linux, since this particular interface is based on a peculiar link type (known as LINUX_SLL or Linux cooked) that adds to packets a special header.

A full list of link types is available here.
