From: Kamala R <kamala@aristanetworks.com>
The behaviour of blackhole and prohibit routes has been corrected by setting the input and output pointers of the dst variable appropriately. For blackhole routes, they are set to dst_discard and to ip6_pkt_discard and ip6_pkt_discard_out respectively for prohibit routes.
