I am not clearly sure that we need to add above 'if statement'.

Same as above.

FOREACH_PORT() returns valid ports, so is it not enough to check like above?
I am not clearly understand which case we need to add above extra if
statements.
Could you please describe?

But I agree we cannot use my previous patch.
We need to fix not only stop_port() but also close_port() like start_port().

Thanks,
Tetsuya
