From 2576a9ace47eba28a682d249d1d6402f891808c9 Mon Sep 17 00:00:00 2001 From: Denis Kenzior Date: Mon, 26 Mar 2018 12:52:42 -0500 Subject: nl80211: Implement TX of control port frames This commit implements the TX side of NL80211_CMD_CONTROL_PORT_FRAME. Userspace provides the raw EAPoL frame using NL80211_ATTR_FRAME. Userspace should also provide the destination address and the protocol type to use when sending the frame. This is used to implement TX of Pre-authentication frames. If CONTROL_PORT_ETHERTYPE_NO_ENCRYPT is specified, then the driver will be asked not to encrypt the outgoing frame. A new EXT_FEATURE flag is introduced so that nl80211 code can check whether a given wiphy has capability to pass EAPoL frames over nl80211.
