NAME

       sys_attrs_fta - fta subsystem attributes

DESCRIPTION

       The  fta  (fta) kernel subsystem is used by the Fiber Distributed Data Interface (FDDI) adapters.  Refer to the sys_attrs(5) reference page
       for an introduction to the topic of kernel subsystem attributes.

	      A value that enables (1) or disables (0) the awakening of a separate thread to handle interrupt service work.

	      The processing of received frames or of completed transmits is typically performed by the driver's interrupt  service  routine.	If
	      minimal_isr is enabled, the interrupt service routine does not do the processing.  Instead, it awakens another thread to do the pro-
	      cessing.	The benefit is that the new thread can run on any other processor, thereby freeing the master processor for  other  inter-
	      rupt  processing and other tasks.  While this may improve overall system performance, there will be an increased latency in the pro-
	      cessing of received FDDI frames.

	      If minimal_isr is disabled, the interrupt service routine processes all received frames and completed transmits.	This can delay the
	      master  processor  from servicing other I/O interrupts and can lead to overall system performance degradation.  However, the latency
	      for handling received FDDI frames will be very low.

	      Default value: 1 (enabled)
