Subject[PATCH 4.14 206/496] iwlwifi: mvm: Direct multicast frames to the correct station
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

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

[ Upstream commit 7c305de2b9548ab6b65fce342c78618bbed5db73 ]

Multicast frames for NL80211_IFTYPE_AP and NL80211_IFTYPE_ADHOC were
directed to the broadcast station, however, as the broadcast station
did not have keys configured, these frames were sent unencrypted.

Fix this by using the multicast station which is the station for which
encryption keys are configured.
