Re: [patch net-next 3/5] ipv6: consider net.ipv6.conf.all sysctls when making decisions

Hello,

IN6_DEV_MAXCONF
	IN6_DEV_HOPLIMIT
	IN6_DEV_MTU

I'm a little bit surprise to set the MTU as the maximum of all/dev
value. Since the default for "all" is IPV6_MIN_MTU, it is probably
harmless, but it could be a little bit surprising for administrators.

 IN6_DEV_USE_TEMPADDR

For this one, the default is zero, except for point-to-point and
loopback, with -1. I didn't see any difference between 0 and -1 in the
current kernel code, but if I missed something, it could be a little
problem.
