From 28029530963223c5c3b94f7a2f9d1343662a1a04 Mon Sep 17 00:00:00 2001 From: Matthew Smith Date: Tue, 26 Sep 2017 13:33:44 -0500 Subject: Add API support to dump IPsec SAs Add an API request message type to dump IPsec SAs. Either all IPsec SAs can be dumped or it can be limited to a single SA ID (numeric ID set at creation time - not an index). Add a handler for incoming messages with the new request type. Add an API response message type containing the data for an IPsec SA. Add VAT support for new message type.
