Start of Receive List (SRL)
This field points to the start of the receive buffer descriptor list. The
descriptor list resides in the Host memory. Writing this register is only valid
when the RX DMA engine is in the stopped state. When stopped, this
register must be written before the START command is given.
RESERVED
Receive List Base Address Register (RX_BASE_ADDR)
This register specifies the start address of the receive buffer list. RX_BASE_ADDR must be 4-DWORD
(16 byte) aligned (e.g. Reserved address bits 3:0 must be 0).
