Hi Yossi, Steffen,
I am using ipsec throug openvpn on one of my machines and it stopped
working since 4.15. Bisection showed that the culprit is:
5efec5c655dd xfrm: Fix eth_hdr(skb)->h_proto to reflect inner IP version
Reverting the patch does fix it for me.
I am seing h_proto being changed from 0x1bac to 0x8 and wireshark
doesn't see the ethernet header anymore:
