* **SK_PASS** on success, or **SK_DROP** on error.

* int bpf_lwt_push_encap(struct sk_buff *skb, u32 type, void *hdr, u32 len)
* Description
* Encapsulate the packet associated to *skb* within a Layer 3
* protocol header. This header is provided in the buffer at
* address *hdr*, with *len* its size in bytes. *type* indicates
* the protocol of the header and can be one of:
*
* **BPF_LWT_ENCAP_SEG6**
* IPv6 encapsulation with Segment Routing Header
* (**struct ipv6_sr_hdr**). *hdr* only contains the SRH,
* the IPv6 header is computed by the kernel.
* **BPF_LWT_ENCAP_SEG6_INLINE**
* Only works if *skb* contains an IPv6 packet. Insert a
* Segment Routing Header (**struct ipv6_sr_hdr**) inside
* the IPv6 header.
*
* A call to this helper is susceptible to change the underlaying
* packet buffer. Therefore, at load time, all checks on pointers
* previously done by the verifier are invalidated and must be
* performed again, if the helper is used in combination with
* direct packet access.
* Return
* 0 on success, or a negative error in case of failure.
*
* int bpf_lwt_seg6_store_bytes(struct sk_buff *skb, u32 offset, const void *from, u32 len)
* Description
* Store *len* bytes from address *from* into the packet
* associated to *skb*, at *offset*. Only the flags, tag and TLVs
* inside the outermost IPv6 Segment Routing Header can be
* modified through this helper.
*
* A call to this helper is susceptible to change the underlaying

* Return
* 0 on success, or a negative error in case of failure.
*
* int bpf_lwt_seg6_adjust_srh(struct sk_buff *skb, u32 offset, s32 delta)
* Description
* Adjust the size allocated to TLVs in the outermost IPv6
* Segment Routing Header contained in the packet associated to
* *skb*, at position *offset* by *delta* bytes. Only offsets
* after the segments are accepted. *delta* can be as well
* positive (growing) as negative (shrinking).

* Return
* 0 on success, or a negative error in case of failure.
*
* int bpf_lwt_seg6_action(struct sk_buff *skb, u32 action, void *param, u32 param_len)
* Description
* Apply an IPv6 Segment Routing action of type *action* to the
* packet associated to *skb*. Each action takes a parameter
* contained at address *param*, and of length *param_len* bytes.
* *action* can be one of:
*
* **SEG6_LOCAL_ACTION_END_X**
* End.X action: Endpoint with Layer-3 cross-connect.
* Type of *param*: **struct in6_addr**.
* **SEG6_LOCAL_ACTION_END_T**
* End.T action: Endpoint with specific IPv6 table lookup.
* Type of *param*: **int**.
* **SEG6_LOCAL_ACTION_END_B6**
* End.B6 action: Endpoint bound to an SRv6 policy.
* Type of param: **struct ipv6_sr_hdr**.
* **SEG6_LOCAL_ACTION_END_B6_ENCAP**
* End.B6.Encap action: Endpoint bound to an SRv6
* encapsulation policy.
