ipsec: enable input features on tunnels
Make the ipsec[46]-tun-input nodes siblings of device-input so that input features can be enabled on them. Register ipsec-tun for feature updates. When a feature is enabled on the device-input arc and the ifindex is an IPSec tunnel, change the end node of the arc for that ifindex to be the appropriate ESP decrypt node. Set a flag on the tunnel to indicate that the feature arc should be started for packets input on the tunnel. Test input policing on ESP IPSec tunnels. Type: improvement Signed-off-by: Brian Russell <brian@graphiant.com> Change-Id: I3b9f047e5e737f3ea4c58fc82cd3c15700b6f9f7
