Re: [PATCH net 1/2] r8152: fix the sw rx checksum is unavailable

[Mark Lord]

What does this code do:

>static void r8153_set_rx_early_size(struct r8152 *tp)
>{
>        u32 mtu = tp->netdev->mtu;
>        u32 ocp_data = (agg_buf_sz - mtu - VLAN_ETH_HLEN - VLAN_HLEN) / 4;
>
>        ocp_write_word(tp, MCU_TYPE_USB, USB_RX_EARLY_SIZE, ocp_data);
>}

How is ocp_data used by the hardware?
Shouldn't the calculation also include sizeof(rx_desc) in there somewhere?

Thanks
