Details:

It will fail when it check IP_ADDR_PCB_VERSION_MATCH in udp_bind function.The
UDP client use UDP_PCB with IPv6 flag. But the type of ipaddr is 0. It haven't
set as IPADDR_TYPE_V6.
I think it need to modify code in pcb_new function. After
ip_set_v6(msg->conn->pcb.ip, 1) at last in this funtion, it need to call
IP_SET_TYPE(&((msg->conn->pcb.ip)->local_ip), IPADDR_TYPE_V6).
