[PATCH] make gianfar eTSEC vlan hw acceleration work again.

Hi.

There seems to be a breakage in the VLAN TX HW acceleration in gianfar (kernel 3.1). It seems like the previous patch that was submitted forgotten to initialize the TX registers.

        if (ndev->features & NETIF_F_IP_CSUM)
                tctrl |= TCTRL_INIT_CSUM;

After this patch, it seems vlan rx/tx for eTSEC works again.

Best regards
