Returns the multicast address associated with an IPv6 address according to RFC 4944 Section 9.
An IPv6 packet with a multicast destination address (DST), consisting of the sixteen octets DST[1] through DST[16], is transmitted to the following 802.15.4 16-bit multicast address:
0 1 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |1 0 0|DST[15]* | DST[16] | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Here, DST[15]* refers to the last 5 bits in octet DST[15], that is, bits 3-7 within DST[15]. The initial 3-bit pattern of "100" follows the 16-bit address format for multicast addresses (Section 12).

Reset the Mac16Address allocation index.
This function resets (to zero) the global integer that is used for unique address allocation. It is automatically called whenever
is called. It may also be optionally called by user code if there is a need to force a reset of this allocation index.
