Subject: [PATCH 3/3] cfg80211: Add support for key operations on NL80211_IFTYPE_MLO_LINK
Date:   Tue, 22 Feb 2022 20:53:13 +0530
Message-ID: <1645543393-22448-4-git-send-email-quic_vjakkam@quicinc.com>
In-Reply-To: <1645543393-22448-1-git-send-email-quic_vjakkam@quicinc.com>
References: <1645543393-22448-1-git-send-email-quic_vjakkam@quicinc.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Allow key operations on NL80211_IFTYPE_MLO_LINK to support configuring
per MLO link keys such as GTK/IGTK/BIGTK.

Add necessary changes in mac80211 and drivers to conform to updated
function signatures
