CSCvk32439 - IPv6 - SISF main thread consumes high CPU DHCPv6/ICMPv6 SOLICIT - 4

I can confirm that we are hitting this bug on a Cisco C9500-40X software version 16.6.4. I had both IPv6 and DHCP Snooping turned on; turned them both off and CPU dropped to normal levels. I still have a use case for IPv6 and DHCP snooping so I'm eagerly awaiting a fix.
