Hello,

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.

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.
