src: Adding support for segment routing header 'srh'
Segment Routing Header "SRH" is new type of IPv6 Routing extension
header (type 4).
SRH contains a list of segments (each is represented as an IPv6 address)
to be visited by packets during the journey from source to destination.
The SRH specification are defined in the below IETF SRH draft.
