Date: Thu, 30 Oct 2014 08:40:56 -0700 From: Tom Herbert <therbert@...gle.com> To: davem@...emloft.net, alexander.duyck@...il.com, netdev@...r.kernel.org Subject: [PATCH net] gre: Use inner mac length when computing tunnel length 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.
