[lwip-users] Two ethernet port with one mac address

[vrnud]

Hi,

I am new to lwip.
basic:
1) I have two ethernt port.(external word interface)
2) Only one ip address is assigned to both the port.
3) RMII interface is used.(3rd port which is going to controller).

Set up:
1) Both ports are connected to external ethernet switch.
2) PC is connected to ethernet switch.

when only one port of DUT (device under test) is connected to ethernet
switch; pinging from pc on individual port is working fine.

Problem:
when both the ports of DUT (device under test) is connected to ethernet
switch; ping is not working.
