synthesis error : "tcp_ip_top.v" instantiates a mismathed version of "network_stack.v"?

[torukskywalker]

Not sure if some directories or files are updated to different versions causing this error.
But we found in the *project.tcl , it sets the src_dir to "rtl", but there is no "rtl", only "hdl" is available.
After fix the src_dir and some minor error (like no NUM_TCP_CHANNELS defined in network_stack.v)
we started to do synthesis, but if failed with errors like below, we checked the network_stack.v and found the
tcp_ip_top.v instantiates a "network_stack" with different in/out ports.
