CSCvi29672 - Implementation of Authenticated Received Chain for ESA

[SR_O]

It's so disappointing how Cisco acts here. The comment from the support technician can be found below:

Currently, there is no specific ETA to implement that, there is an existent feature request to enable ARC and have it natively supported, you can take a look at it here:   https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvi29672

This is one of the most sought out feature and one of the hot topics in this forum.

ARC is expected to be introduced in 16.5 which is expected to be out by the end of this year. this may be subject to change, but given the importance of having this feature on ESA and customers demanding it for several years now, this may be introduced sooner
