/*
* bpf_skb_set_delivery_time
*
* 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.
*
* Returns
* 0 on success.
* **-EINVAL** for invalid input
* **-EOPNOTSUPP** for unsupported delivery_time_type and protocol
