> The generated options is single 32-bit word with
> minimal length specified as 4, no extra fields in the
> option are supported. The option item must be preceded
> with the GTP item itself, and GTP item flags must be
> set accordingly:
>
> - E flag must be set, we are going to provide extension
> - S flag must be reset, because GTP item does not
> provide the value for SQN field, we can't fill this one
> - PN flag must be reset, no N-PDU value provided by
> GTP item either
>
> The raw set example:
>
> set raw_encap 2 eth / ipv4 / udp /
> gtp v_pt_rsv_flags is 0x34 / gtp_psc / end_set
>
> Please, note - value 0x34 provides the required flag combination.
