History
glebius 7845c5b75c o Rearrange struct inpcb fields to optimize the TCP output code path 
considering cache line hits and misses.  Put the lock and hash list
  glue into the first cache line, put inp_refcount inp_flags inp_socket
  into the second cache line.
o On allocation zero out entire structure except the lock and list entries,
  including inp_route inp_lle inp_gencnt.  When inp_route and inp_lle were
  introduced, they were added below inp_zero_size, resulting on not being
  cleared after free/alloc.  This definitely was a source of bugs with route
  caching.  Could be that r315956 has just fixed one of them.
  The inp_gencnt is reinitialized on every alloc, so it is safe to clear it.

This has been proved to improve TCP performance at Netflix.
