ipsec: new api for sa ips and ports updates
Useful to update the tunnel paramaters and udp ports (NAT-T) of an SA
without having to rekey. Could be done by deleting and re-adding the
SA but it would not preserve the anti-replay window if there is one.
Use case: a nat update/reboot between the 2 endpoints of the tunnel.
Type: feature
Change-Id: Icf5c0aac218603e8aa9a008ed6f614e4a6db59a0
