Workaround :

Workaround : 
The message shows that the WLC is receiving IPv6 packets having source address of
::(Unspecified Address).

There are some workarounds:
 - Disconnect the client.
 - Disable IPv6 on the client.
 - Change logging level to critical on the WLC.
 - Disable IPv6 on WLC by "config ipv6 disable" command.

Solution : 
CSCug51714 is raised to remove the message.
Upgrading 007.006(100.000) is a solution.
