Hi,
I just wanted to let you know that data structures in sys/netinet6
now uses time_uptime instead of time_second. This should not be
user-visible, but if you notice there is something wrong with IPv6
after r253970, please let me know. Please do not forget to update
rtsold(8), rtadvd(8), and ndp(8) together when you compile a new
kernel.

New Revision: 253970
URL: http://svnweb.freebsd.org/changeset/base/253970
Log:
- Use time_uptime instead of time_second in data structures for
PF_INET6 in kernel. This fixes various malfunction when the wall time
clock is changed. Bump __FreeBSD_version to 1000041.
- Use clock_gettime(CLOCK_MONOTONIC_FAST) in userland utilities.
