-/** \brief IPsec: Update Security Association keys
+/** \brief Add or Update Protection for a tunnel with IPSEC
+
+    Tunnel protection directly associates an SA with all packets
+    ingress and egress on the tunnel. This could also be achieved by
+    assigning an SPD to the tunnel, but that would incur an unnessccary
+    SPD entry lookup.
+
+    For tunnels the ESP acts on the post-encapsulated packet. So if this
+    packet:
+      +---------+------+
+      | Payload | O-IP |
+      +---------+------+
+    where O-IP is the overlay IP addrees that was routed into the tunnel,
+    the resulting encapsulated packet will be:
+      +---------+------+------+
+      | Payload | O-IP | T-IP |
+      +---------+------+------+
+    where T-IP is the tunnel's src.dst IP addresses.
+    If the SAs used for protection are in transport mode then the ESP is
+    inserted before T-IP, i.e.:
+      +---------+------+-----+------+
+      | Payload | O-IP | ESP | T-IP |
+      +---------+------+-----+------+
+    If the SAs used for protection are in tunnel mode then another
+    encapsulation occurs, i.e.:
+      +---------+------+------+-----+------+
+      | Payload | O-IP | T-IP | ESP | C-IP |
+      +---------+------+------+-----+------+
+    where C-IP are the crypto endpoint IP addresses defined as the tunnel
+    endpoints in the SA.
+    The mode for the inbound and outbound SA must be the same.
