    sys/net              if_var.h 
  Merge if_var.h:1.99 from HEAD to RELENG_6:
    Allocate one of the spare ifnet integer fields to hold if_drv_flags,
    which in the future will hold IFF_OACTIVE and IFF_RUNNING, and have
    its access synchronized by the device driver rather than the
    protocol stack.  This will avoid potential races in the management
    of flags in if_flags.
