From: Stephen Hemminger <[EMAIL PROTECTED]> It doesn't look like spidernet hardware can really checksum all protocols, the code looks like it does IPV4 only. If so, it should use NETIF_F_IP_CSUM instead of NETIF_F_HW_CSUM.
The driver doesn't need it's own get/set for ethtool tx csum, and it should use the standard ethtool_op_get_link.
