Subject: ipv6: always add flag an address that failed DAD with DADFAILED
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=82d3c821e9819e7ca4e051e4c6f4efa9d3da5464;p=pandora-kernel.git

ipv6: always add flag an address that failed DAD with DADFAILED

commit 3d171f3907329d4b1ce31d5ec9c852c5f0269578 upstream.

The userspace needs to know why is the address being removed so that it can
perhaps obtain a new address.

Without the DADFAILED flag it's impossible to distinguish removal of a
temporary and tentative address due to DAD failure from other reasons (device
removed, manual address removal).
