Hello everyone, I got the same problem last year when I tried to use LWIP 1.1.0 stably. Finally, I found the driver bug of net device in the low_level_input and low_level_output function.
I suggest you to check your driver first. In low_level_input function, you should check the packet error and recover the device buffer pointer after drop packet. Also, in low_level_output function, you should send the packet again when you can not get the send success flag over a reasonable time. This is my suggestion. I hope you will get the trouble point.
