  SVN rev 191417 on 2009-04-23 10:59:40Z by rwatson
  
  Move portions of data structure initialization from if_attach() to
  if_alloc(), and portions of data structure destruction from if_detach()
  to if_free().  These changes leave more of the struct ifnet in a
  safe-to-access condition between alloc and attach, and between detach
  and free, and focus on attach/detach as stack usage events rather than
  data structure initialization.
  
  Affected fields include the linkstate task queue, if_afdata lock,
  address lists, kqueue state, and MAC labels.  ifq_attach() ifq_detach()
  are not moved as ifq_attach() may use a queue length set by the device
  driver between if_alloc() and if_attach().
