So I have an Ethernet interface with two IP and MAC addresses. It seems it 
works, except for one thing.
I tested connectivity by running "ping 192.168.1.156" command from a shell on 
the same computer. No reply!
The ARP table is ok (192.168.1.156 is associated to 01.02.03.04.05.06 MAC address). It seems no packets are detected from lwip. 

Besides the fix mentioned by Joel, you can turn off
checksumming in LwIP by something like:

  #if (LWIP_DEBUG > 0)
    #define CHECKSUM_CHECK_IP       0
    #define CHECKSUM_CHECK_TCP      0
    #define CHECKSUM_CHECK_UDP      0
    #define CHECKSUM_CHECK_ICMP     0
    #define CHECKSUM_CHECK_ICMP6    0
    ...
  #endif
