CVS commit: src/sys/netinet6

["Maxime Villard" <maxv%netbsd.org@localhost>]

Module Name:    src
Committed By:   maxv
Date:           Tue Jan 23 15:13:56 UTC 2018

Modified Files:
        src/sys/netinet6: dest6.c

Log Message:
Fix the calculation of the ICMP6 error pointer. It is not correct to use

        pointer = opt - mtod(m, u_int8_t *)

because m may have gone through m_pulldown, and it is possible that
m->m_data is no longer the beginning of the packet.
