 * This file implements Information Fields present in IEEE 802.15.4-2011.
 * Information Fields are in practice similar to the Information Elements(IE)
 * introduced in later revisions of the standard, however, they lack
 * descriptors and common format unlike the IEs. To keep this implementation
 * consistent with the IEEE 802.15.4-2011 std. the present file implements
 * Information Fields not Information Elements.
