[PATCH 51/71] nl80211: Extend add/set station command to support NDI

[Andrei Otcheretianski]

From: Ilan Peer <ilan.peer at intel.com>

When a NAN Data Interface (NDI) station is configured it should
be associated with the NAN Management Interface station to which
it belongs. Thus, when configuring an NDI station to the kernel
also set the corresponding NMI station address.
