11-BETA3 Panic with ip6+ESP, Fatal trap 12, severe outage

[Harry Schmalzbauer]

Hello,

unfortunately my upgrade from 10.3 to 11-BETA3 caused machine outage.
ESP encrypted IPv6-traffic acauses a immediate crash.
Please see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211486
whereI provided this info:

Andrey V. Elsukov rapidly analysed and corrected that in HEAD with r303657.
This solved my problems on stable/11, as updated here https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211486


Thank you very much!
