Can you please add more detail, same also asked in prev version [1]. Btw what
does "flow id won't work" mean, and what is cong or cgid?

Thanks.

Can you please provide more information in commit log, why this change is done,
is it to fix something, if so what is broken with original code, why using "cong
group id" helps instead of using "flow_id" etc..
