Hi All, The IPV6 over IPv4 driver is loaded in my kernel during load time. I was experimenting with netdevice notifiers.
I observed that on doing $ifconfig eth0 down my notifier function is called twice instead of once. If i do $ifconfig eth0 up my notifier function is again called but this time only once. My assumption is, this is because of the IPv6 over IPv4 tunnelling driver which makes a pseudo IPv6 device and is existent as sit0 along with eth0. When i bring the eth0 down it takes down sit0 first and then is shut down. To kernel they are two device eth0 and sit0 , and thus two notification events. And only one when i do eht0 up, may be because i have built the eth0 driver statically into the kernel and thus a notification is generated only for IPv6 tunnelling module during ifconfig eth0 up. I know i am talking wrong mostly, but it my guess . Any help, why is this happening this way?
