There is no much difference on those registers :(
But you could try to replace :

static void atl1e_cal_ring_size(struct atl1e_adapter *adapter, u32 *ring_size)
{
	*ring_size = ((u32)(adapter->tx_ring.count *
		     sizeof(struct atl1e_tpd_desc) + 7
			/* tx ring, qword align */
		     + adapter->rx_ring.real_page_size * AT_PAGE_NUM_PER_QUEUE *
			adapter->num_rx_queues + 31
			/* rx ring,  32 bytes align */
		     + (1 + AT_PAGE_NUM_PER_QUEUE * adapter->num_rx_queues) *
			16 + 15));
			/* tx, rx cmd, dword align   */
}


static int atl1e_setup_ring_resources(struct atl1e_adapter *adapter)
{
.....
	/* Init CMB dma address */
	offset = roundup(offset, 16);
	tx_ring->cmb_dma = adapter->ring_dma + offset;
	tx_ring->cmb = adapter->ring_vir_addr + offset;
	offset += sizeof(u32);
	offset = roundup(offset, 16);

	for (i = 0; i < adapter->num_rx_queues; i++) {
		for (j = 0; j < AT_PAGE_NUM_PER_QUEUE; j++) {
			rx_page_desc[i].rx_page[j].write_offset_dma =
				adapter->ring_dma + offset;
			rx_page_desc[i].rx_page[j].write_offset_addr =
				adapter->ring_vir_addr + offset;
			offset += sizeof(u32);
			offset = roundup(offset, 16);
		}
	}
.....



Just guess, no confidence on it ....
