+Subject: [PATCH] support gre key in ikev1
+
+this implements gre key negotiation in ikev1 similarly to the
+ipsec-tools patch in alpine.
+
+the from/to port pair is internally used as gre key for gre
+protocol traffic selectors. since from/to pairs 0/0xffff and
+0xffff/0 have special meaning, the gre keys 0xffff and 0xffff0000
+will not work.
+
+this is not standard compliant, and should probably not be upstreamed
+or used widely, but it is applied for interoperability with alpine
+racoon for the time being.
