Edge Datapath will parse the IPv6 header for unicast packets when destination IP is the uplink IP address of the SR instance, or SR CPU's port IP address. The payload length field of the IPv6 header is not processed with correct byte order.
As a result, payload length of multiples of 256 bytes are treated as malformed packets and and are dropped.
This issue is resolved in NSX 3.1.0 and higher.
