Hello,

Does someone know how to add a new sysctl parameter?

I like to add a tcp-level sysctl parameter to control my own function.
I have tried to modify /sys/netinet/tcp_var.h, tcp_subr.c and
/usr/include/netinet/tcp_var.h, then re-compile sysctl command.

But it seems not work, I can't see my new sysctl var with sysctl.

Could you give me a guide?

Thanks.
