so how about this situation: 1. a device, A, in a network using static IP for a while already, so it and the server knows each other's MAC. 2. device A changed its Ethernet card and keeps it's static IP. Then later server sends out an ARP request for an IP other than A's 3. in current implementation of lwip, A uses this ARP request to update its own table. 4. when A sends a message to server, it doesn't send out ARP request because it has server's MAC in its table already. 5. Therefore, server still has the old IP and MAC pair in its table, and it will cause problem until current entry expires.
