Subject: [PATCH 1/1] cfg80211: Allow AP/P2PGO to indicate port authorization to peer STA/P2PClient
Date:   Thu, 14 Jul 2022 11:00:28 +0530
Message-Id: <5ee2d7c8f809c3d7f773ad4231cb894af850e1a2.1657720730.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.
