Mac address always change for any packet-in message

[bruce-szg]

I installed linc-switch on two raspberry pi and connected them with two hosts. However, it always change switches/host mac address, it I ping a host from another host. Whatever it is switch's ingress mac address or host mac address. It will result in that linc-switch will report a packet-in message to the controller for any message from/to the same hosts. Does linc-switch have some setting to frequently update mac address?

I set the static IP in the raspberry pi for communicating with controller. The Ryu controller is installed in a PC.
I connected a host and a server through the LINC-switch, and I can ping each other, but when I wanted to access the server, It always downloaded the html automatically. I don't find the reason.
ps: I used USB-to-RJ45 to extend the eth, and the switches mac address didn't change.

@topspeedbell could you explain your topology more precisely? Where the LINC is installed etc.

@mentels sorry for replying you so late.
********** host----AP(WiFi)----LINC-Switch(Raspberry Pi)----Server ************
***************************************** | ****************************************
********Ryu(controller) ***
the topology is simply depicted.
the LINC is installed in the Raspberry Pi, and the Ryu is installed in a PC. The AP(WiFi) is configured as the bridge mode.
At first, We use the link like this (host----AP(WiFi)----Server), and the host can access the Server well. Then, When we add the LINC-Switch and the Ryu add the flow table as described here [1], the host and the Server can ping each other, but the host can not access the server well, it always replies that "Method Not Implemented to/index.html not supported".
