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?
