Detailed Description

Performs 6LoWPAN compression of IPv6 packets as specified by RFC 4944 and RFC 6282

This module acts as a shim between IPv6 and a generic NetDevice.

The module implements RFC 4944 and RFC 6282, with the following exceptions:

MESH and LOWPAN_BC0 dispatch types are not supported
HC2 encoding is not supported
IPHC's SAC and DAC are not supported
