3.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Govindarajulu Varadarajan <gvaradar@xxxxxxxxx> [ Upstream commit 7596175e99b3d4bce28022193efd954c201a782a ] In case of IPv6 pkts, ipv4_csum_ok is 0. Because of this, driver does not set skb->ip_summed. So IPv6 rx checksum is not offloaded. Signed-off-by: Govindarajulu Varadarajan <gvaradar@xxxxxxxxx> Signed-off-by: David S.
