RELENG_6:

  Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
  IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
  ifnet.if_drv_flags.  Device drivers are now responsible for
  synchronizing access to these flags, as they are in if_drv_flags.  This
  helps prevent races between the network stack and device driver in
  maintaining the interface flags field.

  Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
  some less so.
