From 6a671a50f8199b3e1fe49fa8afff0fc8335da79c Mon Sep 17 00:00:00 2001 From: Denis Kenzior Date: Mon, 26 Mar 2018 12:52:41 -0500 Subject: nl80211: Add CMD_CONTROL_PORT_FRAME API This commit also adds cfg80211_rx_control_port function. This is used to generate a CMD_CONTROL_PORT_FRAME event out to userspace. The conn_owner_nlportid is used as the unicast destination. This means that userspace must specify NL80211_ATTR_SOCKET_OWNER flag if control port over nl80211 routing is requested in NL80211_CMD_CONNECT, NL80211_CMD_ASSOCIATE, NL80211_CMD_START_AP or IBSS/mesh join.
