Subject: [PATCH] wifi: ath10k: add support to allow broadcast action from RX
Date:   Tue, 17 Oct 2023 09:53:06 -0700
Message-Id: <20231017165306.118779-1-prestwoj@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Advertise support for multicast frame registration and update the RX
filter with FIF_MCAST_ACTION to allow broadcast action frames to be
received. Broadcast action frames are needed for the Device
Provisioning Protocol (DPP) for Presence and PKEX Exchange requests.
