Smarts SAM: Trap exploder is not forwarding IPv6 traps with the proper source IPv6 address

Issue/Introduction
Symptoms:
User has noted that when their trap exploder (trap adapter designed to forward incoming traps to another trap adapter) receives a trap from an IPv6 source, it is rewriting the source IP address to the IPv4 address of the trap exploder. This creates inaccurate and misleading results in Smarts when those traps are received.

Environment
VMware Smart Assurance - SMARTS
Cause
The user had configured the FORWARD statements in trapd.conf to use the -nosmtrapaddr option. While this option didn't cause any problems with IPv4 sources, it was preventing IPv6 sources from being properly written in the forwarded traps.
Resolution
In this case removing the -nosmtrapaddr option from the FORWARD lines in the trapd.conf fixed the issue.
