Subject: [PATCH v7 1/3] cfg80211: modify prototype for change_beacon
Date:   Wed, 9 Nov 2022 13:47:18 -0800
Message-ID: <20221109214720.6097-2-quic_alokad@quicinc.com>
In-Reply-To: <20221109214720.6097-1-quic_alokad@quicinc.com>
References: <20221109214720.6097-1-quic_alokad@quicinc.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Modify the prototype for change_beacon() in struct cfg80211_op to
accept struct cfg80211_ap_settings instead of cfg80211_beacon_data
so that it can process data in addition to beacons.
Above change also requires similar modifications to prototype of
ieee80211_change_beacon() and driver specific functions for
successful compilation.
