Bjoern A. Zeeb dd4d5a5ffb IPv6: set ifdisabled in the kernel rather than in rc 
Enable ND6_IFF_IFDISABLED when the interface is created in the
kernel before return to user space.

This avoids a race when an interface is create by a program which
also calls ifconfig IF inet6 -ifdisabled and races with the
devd -> /etc/pccard_ether -> .. netif start IF -> ifdisabled
calls (the devd/rc framework disabling IPv6 again after the program
had enabled it already).

In case the global net.inet6.ip6.accept_rtadv was turned on,
we also default to enabling IPv6 on the interfaces, rather than
disabling them.
