  Adopt the slightly weaker consistency locking approach used in IPv4 raw
  sockets for IPv6 raw sockets: separately lock the inpcb for determining
  the destination address for a connect()'d raw socket at the rip6_send()
  layer, and then re-acquire the inpcb lock in the rip6_output() layer to
  query other options on the socket.  Previously, the global raw IP socket
  lock was used, which while correct and marginally more consistent, could
  add significantly to global raw IP socket lock contention.
