+/* This set of attributes controls behavior of the

+ * __msg Message expected to be found in the verifier log.
+ * Multiple __msg attributes could be specified.

+ * __success Expect program load success in privileged mode.
+ *
+ * __failure Expect program load failure in privileged mode.
+ *
+ * __log_level Log level to use for the program, numeric value expected.
+ *
+ * __flag Adds one flag use for the program, the following values are valid:
+ * - BPF_F_STRICT_ALIGNMENT;
+ * - BPF_F_TEST_RND_HI32;
+ * - BPF_F_TEST_STATE_FREQ;
+ * - BPF_F_SLEEPABLE;
+ * - BPF_F_XDP_HAS_FRAGS;
+ * - A numeric value.
+ * Multiple __flag attributes could be specified, the final flags
+ * value is derived by applying binary "or" to all specified values.
