+Subject: [PATCH] ip6_tunnel: Fix missing tunnel encapsulation limit option
+
+The IPv6 tunneling code tries to insert IPV6_TLV_TNL_ENCAP_LIMIT and
+IPV6_TLV_PADN options when an encapsulation limit is defined (the
+default is a limit of 4).  An MTU adjustment is done to account for
+these options as well.  However, the options are never present in the
+generated packets.
+
+The issue appears to be a subtlety between IPV6_DSTOPTS and
+IPV6_RTHDRDSTOPTS defined in RFC 3542.  When the IPIP tunnel driver was
+written, the encap limit options were included as IPV6_RTHDRDSTOPTS in
+dst0opt of struct ipv6_txoptions.  Later, ipv6_push_nfrags_opts was
+(correctly) updated to require IPV6_RTHDR options when IPV6_RTHDRDSTOPTS
+are to be used.  This caused the options to no longer be included in v6
+encapsulated packets.
+
+The fix is to use IPV6_DSTOPTS (in dst1opt of struct ipv6_txoptions)
+instead.  IPV6_DSTOPTS do not have the additional IPV6_RTHDR requirement.
+
+Fixes: 1df64a8569c7: ("[IPV6]: Add ip6ip6 tunnel driver.")
+Fixes: 333fad5364d6: ("[IPV6]: Support several new sockopt / ancillary data in Advanced API (RFC3542)")
