Subject:   ping6: failed to get receiving hop limit

Hello,

Sometimes ping6 command writes the following warning to stderr:

ping6: failed to get receiving hop limit

I can easily reproduce this with 
for n in `jot - 1 1000` ; do /sbin/ping6 -n -c 5 $HOST > /dev/null ; done

It is very likely that even 100 repetitions is enough to catch this.

Other than this warning IPv6 network seems to work properly.

What does it mean?

Thanks.
