/**
 * This header generates MIPE tracepoint declaration BLOB at
 * compile time.
 *
 * Before including this header, the following parameters
 * must be defined:
 *
 * MIPE_HEADER_BLOB_VAR_NAME: the name of the variable
 * where the result BLOB will be stored.
 *
 * MIPE_HEADER_TP_LIST: the list of tracepoints to process.
 * It should be defined as follows:
 * #define MIPE_HEADER_TP_LIST \
 *     TP_DESC(FIRST_TRACEPOINT, "Some description", "@II", "first_arg,second_arg") \
 *     TP_DESC(SECOND_TRACEPOINT, "Some description", "@II", "first_arg,second_arg") \
 *     etc.
 * Where the first argument is tracepoints name, the second
 * argument is a short tracepoint description, the third argument
 * argument types (see MIPE documentation), and the fourth argument
 * is comma separated argument names.
 *
 * MIPE_HEADER_TP_LIST_COUNT: number of entries in MIPE_HEADER_TP_LIST.
 *
 * MIPE_HEADER_PKT_CLASS: MIPE packet class.
