/**
 *  Packing Macros.
 *
 *  Syntax: MS_PACK_<Endian-ness LE/BE>_<no_of_bytes>_BYTE
 *
 *  Usage: Based on the endian-ness defined for each protocol/profile layer,
 *  appropriate packing macros to be used by each layer.
 *
 *  Example: HCI is defined as little endian protocol,
 *  so if HCI defines HCI_PACK_2_BYTE for packing a parameter of size 2 byte,
 *  that shall be mapped to MS_PACK_LE_2_BYTE
 *
 *  By default both the packing and unpaking macros uses pointer to
 *  a single or multi-octet variable which to be packed to or unpacked from
 *  a buffer (unsinged character array).
 *
 *  For the packing macro, another variation is available,
 *  where the single or multi-octet variable itself is used (not its pointer).
 *
 *  Syntax: MS_PACK_<Endian-ness LE/BE>_<no_of_bytes>_BYTE_VAL
