Subject: [PATCH v2 1/1] cfg80211: Allow AP/P2PGO to indicate port authorization to peer STA/P2PClient
Date:   Fri, 15 Sep 2023 10:47:47 +0530
Message-Id: <d19fc849488e63cf367029b614289c324f531ae8.1694751711.git.vinayak.yadawad@broadcom.com>

In 4way handshake offload, cfg80211_port_authorized enables driver
to indicate successful 4way handshake to cfg80211 layer. Currently
this path of port authorization is restricted to interface type
NL80211_IFTYPE_STATION and NL80211_IFTYPE_P2P_CLIENT. This patch
extends the support for NL80211_IFTYPE_AP and NL80211_IFTYPE_P2P_GO
interfaces to authorize peer STA/P2P_CLIENT, whenever authentication
is offloaded on the AP/P2P_GO interface.
