Penned by Henning Brauer on 20140608 10:14.46, we have:
| since no consensus could be found yet for a new command line option to
| ifconfig, heck, not even about wether it is needed, I propose this for
| now.
|
| 1) make "ifconfig <if> inet6 eui64" reset the NOINET6 flag
| unconditionally, so a link-local will be assigned if there isn't one
| yet.

| 2) turn the NOINET6 flag on by default.
| As said previously, it will be reset and thus a link-local assigned
| transparently if either
| -rtsol(d) is run
| -an inet6 address is assigned
| -ifconfig <if> inet6 eui64 is run
| and thus should be entirely transparent for the vast majority of inet6
| users.
