  Modified files:
    sys/net              if_var.h 
  Log:
  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.
