Sorry, I another problems want to ask.

I already know what codes cause eth1's(xnetif_1) gateway be "255.255.0.0",
that is a function reads ini file error, so it can reads a right gateway
"192.168.191.254" after I write a correct function.

Next, I trace packet when I ping eth1(192.168.191.220), the packet send to
"etharp_query(netif, dst_addr, q)" on etharp_output(), it returns "ERR_OK",
but the packet already loss, I don't understand.

ps: I set all devices and PC on the same subnet, and device_1 and device_2
are no problems after pinging them, so my two interfaces can work on the
same subnet.
