Re: [PATCH net-next] ipv6: recreate ipv6 link-local addresses when increasing MTU over IPV6_MIN_MTU

Might be a bit longer.  I just realized that I think there is another 
bug here where you are going through the NETDEV_UP path even though the 
interface isn't up.  I'll run through some testing this morning to work 
out the kinks.

When you wrote this, I noticed that if someone removes the LL addresses
to disable the interface and raises the MTU again, we would also start
adding link-local addresses. Probably we need to safe the last state of
disable_ipv6 somewhere in the parent interface. :(

Maybe there is an easier solution for that.

Thanks for your patch, it looks cleaner!

Bye,
