[lwip-users] MAC address always zero in ethernet_input

I've not been able to get lwip+freertos+stm32f4 to work between a PC client and a STM TCP server with direct connection and static IPs (host is 169.254.134.127, STM is 169.254.134.254). It appears that tcpip_input is working correctly (etharp is processed), but the MAC addresses always return z
