 * in the user space, define a set of messages they recognize.
 * Each of this message will have an header of type tAniMsgHdr defined below.
 * Each Netlink message to/from a kernel module will contain only one
 * message which is preceded by a tAniMsgHdr. The maximun size (in bytes) of
 * a netlink message is assumed to be MAX_PAYLOAD bytes.
