+ * long bpf_skb_set_delivery_time(struct sk_buff *skb, u64 dtime, u32 dtime_type)
+ * Description
+ * Set a *dtime* (delivery time) to the __sk_buff->tstamp and also
+ * change the __sk_buff->delivery_time_type to *dtime_type*.
+ *
+ * When setting a delivery time (non zero *dtime*) to
+ * __sk_buff->tstamp, only BPF_SKB_DELIVERY_TIME_MONO *dtime_type*
+ * is supported. It is the only delivery_time_type that will be
+ * kept after bpf_redirect_*().
+ *
+ * If there is no need to change the __sk_buff->delivery_time_type,
+ * the delivery time can be directly written to __sk_buff->tstamp
+ * instead.
+ *
+ * *dtime* 0 and *dtime_type* BPF_SKB_DELIVERY_TIME_NONE
+ * can be used to clear any delivery time stored in
+ * __sk_buff->tstamp.
+ *
+ * Only IPv4 and IPv6 skb->protocol are supported.
+ *
+ * This function is most useful when it needs to set a
+ * mono delivery time to __sk_buff->tstamp and then
+ * bpf_redirect_*() to the egress of an iface. For example,
+ * changing the (rcv) timestamp in __sk_buff->tstamp at
+ * ingress to a mono delivery time and then bpf_redirect_*()
+ * to sch_fq@phy-dev.
+ * Return
+ * 0 on success.
+ * **-EINVAL** for invalid input
+ * **-EOPNOTSUPP** for unsupported delivery_time_type and protocol
