Normal cell routing for unknow cells received on port A. "xxx1" = Port A,
"xx1x" = Port B, "x1xx" = Port C, "1xxx" RX SAR. Cells can be broadcast to
multiple destinations by setting multiple bits in this field to '1'.

Value by which the HEC generated on UTOPIA will be XORed before
being transmitted. Should match the value used by the PHY.
Reserved. Must always be "0000_0000_0"

If the cell fill of the Port C output FIFO becomes greater than
this value, cells from the TX SAR input FIFO will be blocked. 0h
= no backpressure
