Set this to value 00H.
This 2-bit number denotes the size in Blocks of FIFO for the PHYID specified in the RXSDQ
FIFO Indirect Address register. The bandwidth is related to the size of the FIFO that will be
allocated to the PHY. The values to be programmed are given in the Operation section.
For correct operation of the S/UNI-2488, this field must be set to 11.
This should be set to 00H.
