Since when "Fixes:" tag becomes mandatory for a stable patch?
At least netdev-FAQ is not updated. ;-) I 100% agree "Fixes:"
is helpful when backporting patches, but it is not mandatory currently.

For this patch, I was too lazy to dig the history, it looks like this is
caused by the following commit:

commit c15b1ccadb323ea50023e8f1cca2954129a62b51

    ipv6: move DAD and addrconf_verify processing to workqueue

Thanks.
