Follow-up Comment #4, bug #57710 (project lwip):

Hi Benjamin,

We are not using IPv6 but its default enabled in my LWIP.
I will disable it as we don't have any plans on working on IPv6.

I have added the change which you suggested in below function and need to test
err_t Etherdo_connected(void arg, struct tcp_pcb newpcb, err_t err) {
    // do something
    ip_set_option(newpcb, SOF_KEEPALIVE);

    *pcb_tcp = pcb;*

I am using the "newpcb" during tcp_write(). I amcopying the content of newpcb
to my local pcb_tcb and using that for data transmission.

I will remove the IPv6 and check again now and will get back to you with
