ipv6: enable IPV6_FLOWLABEL_MGR for getsockopt
It is already possible to set/put/renew a label with IPV6_FLOWLABEL_MGR and setsockopt. This patch add the possibility to get information about this label (current value, time before expiration, etc). It helps application to take decision for a renew or a release of the label. v2: * Add spin_lock to prevent race condition * return -ENOENT if no result found * check if flr_action is GET v3: * move the spin_lock to protect only the relevant code Signed-off-by: Florent Fourcot <florent.fourcot@enst-bretagne.fr> Acked-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.
