Ethernet (the default) is the standard Ethernet 2.0 encapsulation for
hosts that support Ethernet. This type is required for point-to-point or
any type of X.25 interface.) If you are defining a LAN interface (Ethernet
or IEEE 802.x), you must specify the encapsulation method supported
by the attached network.

802.2 can be used for hosts supporting IEEE 802.2 over IEEE 802.3
LAN interfaces. The 802.2 structure is encapsulated as shown, and is
further encapsulated within a medium-specific 802.x packet.
