sysConfigSwitchingMode

The switch can operate as a high speed cut-through
switch, or as a traditional store-and-forward switch.
Cut-through switching of frames is enabled when
this object is set to fastForward(3) or fragmentFree(2).
This works to reduce buffering latency by attempting to
forward a frame before reception is completed.
          
Switches operating with firmware versions greater
than or equal to 6.00 support only fragmentFree(2) and
sotre-and-forward(1).
          
Broadcast frames are always switched using the
store-and-forward(1) method.  Multicast frame switching
may be forced to the store-and-forward(1) mode using
the object sysConfigMulticastStoreAndForward.
The switching of any types of frame automatically reverts
to the store-and-forward(1) method whenever the
switch is configured to monitor frames internally (see the
                object sysConfigMonitorPort).
          
The default value for this object for firmware version
greater than or equal to 6.00 is fragmentFree(2).
The default value for this object for firmware version
less than 6.00 is fastForward(3).
          
store-and-forward: entire frame is buffered before it is
                   forwarded to the appropriate destination.
          
fragmentFree     : forward the frame to the appropriate
                   destination after 64 bytes plus preamble
                   have been received.
          
fastForward      : minimize latency by making the forwarding
                   decision as soon as possible during frame
                   reception (after 6 bytes plus preamble).
