Description (partial)

Piggybacked message received from MME on Cisco SGW ingress interface is forwarded to PGW as separate messages. Hence PGW should handle two separate messages instead of one piggybacked message.

The issue is seen for the following scenario.
At SGW even when (MBReq. + CBResp.) piggybacked message is received, SGW does not send these 2 messages as piggybacked to PGW. Instead SGW sends as 2 separate messages.
