    xfrm: remove gso_segment indirection from xfrm_mode · 7613b92b
    Florian Westphal authored
    These functions are small and we only have versions for tunnel
    and transport mode for ipv4 and ipv6 respectively.
    
    Just place the 'transport or tunnel' conditional in the protocol
    specific function instead of using an indirection.
