// This module implements a trivial MAC protocol for use in ~AckingWirelessInterface.
//
// The implementation provides packet encapsulation and decapsulation, but it
// doesn't have a real medium access protocol. It doesn't provide carrier sense
// mechanism, collision avoidance, collision detection, but it provides optional
// out-of-band acknowledgement. Higher layer packets should have MacAddressReq
// tag.
//
// See ~AckingWirelessInterface for rationale and details.
