issPortCtrlSwitchModeType

This object is used to configure switching mode configuration
per port-level.
              
Switching mode can be configured only for physical ports.
              
When configured as StoreForward(2), the port operates in a
store-and-forward mode  and the switch checks each frame for
cyclic redundancy check (CRC) errors  before forwarding them
to the network. Each frame is  stored until the entire frame
has been received and  checked. Because the switch waits for
forwarding the frame until the entire frame has been received
and checked, the switching  speed in Store-Forward switching
mode is slower than  the switching speed  in Cut-Through
switching modes.
              
When configured any of the cut-through  modes, the switch
operates in Cut-Through switching mode and start forwarding
the  frame as soon as the  switch has read the  destination
details in the packet header. A switch in  Cut-Through mode
forwards  the data  before it has  completed receiving  the
entire frame. The switching  speed in Cut-Through  mode  is
faster than the switching speed in Store-Forward switching
mode.
              
Switching mode configuration:
CutThroughSameSpeed(1) : Cut-through forwarding between same speed
                         ports
StoreForward(2)        : Store and forward switching mode
CutThroughSlowToFast(3): Cut-through forwarding between slower to
                         faster speed ports.
CutThroughFastToSlow(4): Cut-through forwarding between faster to
                         slower speed ports.
NOTE:
Few platforms supports extended Cut-Through mode for ports with
mismatched speeds.(eg. slow-to-fast, fast-to-slow).
Platforms which doesn't support extended Cut-Through mode,
Cut-Through same speed shall be considered as Cut-Through
switching mode
