Subject: [PATCH 2/2] bna: Add Generic Netlink Interface

This patch adds the generic netlink communication interface to BNA driver. The
in-kernel generic netlink infrastructure can be used to collect hardware
specific control information and control attributes. The driver makes use of
the "doit" handler provided by the generic netlink layer to accomplish this.
