Subject: forcedeth: fix checksum flag
From: Ayaz Abdulla <aabdulla@xxxxxxxxxx>
Fix the checksum feature advertised in device flags. The hardware support
TCP/UDP over IPv4 and TCP/UDP over IPv6 (without IPv6 extension headers).
However, the kernel feature flags do not distinguish IPv6 with/without
extension headers.
Therefore, the driver needs to use NETIF_F_IP_CSUM instead of
NETIF_F_HW_CSUM since the latter includes all IPv6 packets.
A future patch can be created to check for extension headers and perform
software checksum calculation.
