SHIFT_VCI
Selects the VCI Address range used for mapping to queue numbers. This bit
only controls the reception of cells. This field is not used if VP_MODE_EN is
set.
0) Will use VCI(7:0) as the queue number if VCI(8) = 1.
2) Will use VCI(11:4) as the queue number if VCI(12) = 1.
VP_MODE_EN
When set uses the VPI field for Line selection and uses VCI field for OAM
cell detection. This bit only controls the reception of cells. This bit can only
be set if all lines are in UDF mode. In particular:
1) VPI[2:0] selects line within the A1SP
2) If VCI <= 31 then interpret cell as OAM cell and place in OAM buffer.
3) Queue 0 will be assumed and no VCI bits need to be used to indicate
queue number
Note that VP_MODE_EN should only be set in the Utopia 1 or Utopia 2 single
address modes.
