When I added copying of pbuf data to application buffer inside TCP 
receive callback, one interesting thing happened - TX side got 
completely unresponsive!

I have been copying it like this:
if(p->tot_len < BUF_SIZE) {
    if (pbuf_copy_partial(p, (void*)buf, p->tot_len, 0) != p->tot_len) {
            xil_printf("total copied != p->tot_len\n");
        }
    }

I guess that using pbuf_copy_partial is a valid way to do the copying to 
application buffer, isn't it? This seems like some memory corruption.
