//* description: MAC layer class for 802.11

// Implementation of the 802.11b MAC protocol. This module is intended
// to be used in combination with the SnrEval80211 and Decider80211
// modules as physical layer.
// This module supports ad-hoc mode only (does not generate or handle
// management frames), and does not support fragmentation, RTS threshold,
// duplication detection and recovery.
