For beet mode, when it's ipv6 inner address with nexthdrs set, the packet format might be: ---------------------------------------------------- | outer | | dest | | | ESP | ESP | | IP hdr | ESP | opts.| TCP | Data | Trailer | ICV | ---------------------------------------------------- The nexthdr from ESP could be NEXTHDR_HOP(0), so it should continue processing the packet when nexthdr returns 0 in xfrm_input(). Otherwise, when ipv6 nexthdr is set, the packet will be dropped. I don't see any error cases that nexthdr may return 0. So fix it by removing the check for nexthdr == 0.
