Why is it like this?Is it expected?If so, how should I unload ipv6 module?
As long as an interface is up you cannot unload a module. This means when any interface has an IPv6 Address (eth0, lo ....) you cannot unload the module. You have to shut down (remove) all IPv6 Addresses.
Is "reboot" the only option we are left with? Please let me know the info.at the moment you're not allowed to unload the ipv6 module from the kernel. that was a design choice taken from linux kernel developers.
I'm not sure wheter this is the case. You can try the method above, but I may be wrong. Guido
