How to disable tryforward ?

Hi, Tryforwad have merged 3 yeas ago, and it haven’t a sysctl to disable it , so ECMP was broken past 3 years. Olivier has fired a bug : https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225792 , it seems that a few of people cares it. Andrey said maybe some ipsec policy can disable tryforward.
