3.16.7-ckt1 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Tom Herbert <therbert@xxxxxxxxxx> commit 14051f0452a2c26a3f4791e6ad6a435e8f1945ff upstream. Currently, skb_inner_network_header is used but this does not account for Ethernet header for ETH_P_TEB. Use skb_inner_mac_header which handles TEB and also should work with IP encapsulation in which case inner mac and inner network headers are the same. Tested: Ran TCP_STREAM over GRE, worked as expected. Signed-off-by: Tom Herbert <therbert@xxxxxxxxxx> Acked-by: Alexander Duyck <alexander.h.duyck@xxxxxxxxxx> Signed-off-by: David S.
