Hi,

Some user has posted a bug report on ipv6 and DAD:
http://bugs.alpinelinux.org/issues/2773

Basically, ifup of an ipv6 interface will return with success before
the configured address is ready to use due to DAD. When a service later
tries to bind to the address it fails.

In debian's ifupdown then have solved it with this:
http://anonscm.debian.org/hg/collab-maint/ifupdown/rev/a7e1677e7efc

I wonder if this fix should be ported to busybox or if anyone has better
ideas?
