Simplify; clear then set flags to ia4_flags (NFCI)
This change is not right.
You are clearing the flags for an already existing address and now
allows this:
ifconfig bge0 1.2.3.4/16
address becomes tentative
ifconfig bge0 1.2.3.4/16
address flags cleared, address can be used before DaD finishes.
Can we match it to the inet6 path and at least remember if existing
flags were TENTATIVE | DETACHED? That is only done there because we can
update flags from userland, we have no mechanism for this in inet hence
the slight difference.
I would also be happier with always setting DETACHED on link down, but
only setting TENTATIVE if ip_dad_count > 0.
Would that help solve your issue with GARP? What is GARP anyway?
