    ipv6: sr: add helper functions for seg6local · d7a669dd
    David Lebrun authored
    This patch adds three helper functions to be used with the seg6local packet
    processing actions.
    
    The decap_and_validate() function will be used by the End.D* actions, that
    decapsulate an SR-enabled packet.
    
    The advance_nextseg() function applies the fundamental operations to update
    an SRH for the next segment.
    
    The lookup_nexthop() function helps select the next-hop for the processed
    SR packets. It supports an optional next-hop address to route the packet
    specifically through it, and an optional routing table to use.
