Subject: [PATCH] wiphy: Set the linkmode and operstate of the link

We need to set the linkmode and operstate after successful
authentication.

Initial value for linkmode is 1 (user space controlled) and
IF_OPER_DORMANT for opermode. After successful authentication,
the operstate is set to IF_OPER_UP.

More specific details can be seen in kernel sources at
https://www.kernel.org/doc/Documentation/networking/operstates.txt
