/**
    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).
