2.6.25-stable review patch. If anyone has any objections, please let us know. ------------------ From: Ayaz Abdulla commit edcfe5f7e307846e578fb88d69fa27051fded0ab upstream 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.
