I am new to Linux. I would like to understand the rules and etiquettes
of engaging with the community. I have read the materials that I could
find. As I work with Linux I come across situations for which I can not
seem to find any answers. Hopefully folks on the list can answer them.

David,
Thanks a lot for your prompt response. Do you have a specific
solution
in mind or will the calls be replaced with simple checks ?
There is upcoming work for that, but not specific to TCP
little different behavior is desired it can be achieved and
common code could still be shared. Of course you can not say much
without looking at the code but will you even entertain such a change ?

I am working on a change which introduces a couple of indirect function
calls in the fast path. I used indirect function calls instead of
"if/else" as it keeps the code cleaner and more readable and provides
for extensibility.
I do not expect any measurable overhead as modern CPU's use pre-fet

Making Linux conform to standards and behavior that is logical seems
like a good enough reason.

I am looking at a system which is configured for IPv6 only but sits in a
