Bits 31 to 0—Receive Descriptor Start Address 31 to 0 (RDLA31 to RDLA0)
Notes: The lower bits are set as follows according to the specified descriptor length.
16-byte boundary: RDLA[3:0] = 0000
32-byte boundary: RDLA[4:0] = 00000
64-byte boundary: RDLA[5:0] = 000000
Modifications made to this register during reception are invalid. This register should only
be modified while reception is disabled.
