Test Plan

Here is my current netflow export configuration and it works:

kldstat -qm ng_netflow || kldload ng_netflow
kldstat -qm ng_ether || kldload ng_ether
kldload ./ng_ksocket.ko
ngctl mkpeer vtnet0: netflow lower iface0
ngctl name vtnet0:lower netflow          
ngctl connect vtnet0: netflow: upper out0
ngctl mkpeer netflow: ksocket export9 inet6/dgram/udp6
ngctl name netflow:export9 ngk
ngctl msg ngk: connect inet6/[fdb5:c59b:114e:8db4::1]:4444

I have tested this for tcp6 protocol, msg bind, and link-local with [fe80::1%vtnet0]:4444.

sys/netgraph/ng_ksocket.c
62	What does require if_var.h?

Also, any meaningful change to a manual page requires bumping the .Dd value at the beginning of the page to today's date.

Bump .Dd in ng_ksocket.4
update value from January 9, 2012 to January 9, 2025

sys/netgraph/ng_ksocket.c
62	I am using `ifunit()` at line 352, and its function declared in <net/if_var.h>. Maybe I think it's required due to my lack of knowledge, Should I remove it?
