Guillaume Nault f778941913 vxlan: Pull inner IP header in vxlan_rcv(). ... Ensure the inner IP header is part of skb's linear data before reading its ECN bits. Otherwise we might read garbage. One symptom is the system erroneously logging errors like "vxlan: non-ECT from xxx.xxx.xxx.xxx with TOS=xxxx". Similar bugs have been fixed in geneve, ip_tunnel and ip6_tunnel (see commit 1ca1ba465e ("geneve: make sure to pull inner header in geneve_rx()") for example). So let's reuse the same code structure for consistency. Maybe we'll can add a common helper in the future.
