I see, this could make trouble for IPV6 RAW sockets. Can you please send
a patch for this and cc linux-bluetooth and linux-wpan. Also add some
comment why we do this is here, because the RAW socket issue.
Or just send it as RFC (means replace the PATCH into RFC in the
subject). Then we can talk about a better solution if this isn't a
perfect solution.
Also remove the unnecessary brackets -> checkpatch should show an error
because this.
