            Description

            The current DHCP client implementation configures a gateway IP address even if the DHCP server does not provide a gateway address in the DHCP-OFFER. The gateway address will be set to the network address + 1.

            I would expect the gateway address to be 0.0.0.0 in case the DHCP server does not provide a gateway address.

            This was fixed for earlier LWIP releases (based on upstream version V1.4) with             PSLWIP-393, but was reintroduced by accident with integration of upstream LWIP V2)
