Adding a new field counting 'bounds ports' without being netns ready is a total mistake,
as it is useless by current standards.

The first thing that users will do is add proper netns support, with extra complexity in the kernel.

So, instead of pushing some incomplete feature, trying to fool ourselves with a sentiment of 'small cost'
that will later need another 100 lines of code in the kernel, please give us the complete picture.

I am just saying, you can of course ignore my feedback.
