Subject: [PATCH 2/7] wifi: rtw89: 8851b: fill BB related capabilities to chip_info
Date:   Fri, 19 May 2023 11:14:55 +0800
Message-ID: <20230519031500.21087-3-pkshih@realtek.com>
In-Reply-To: <20230519031500.21087-1-pkshih@realtek.com>
References: <20230519031500.21087-1-pkshih@realtek.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 7BIT
Content-Type:   text/plain; charset=US-ASCII
Precedence: bulk

These capabilities include helpers of BT coexistence, RX PPDU status
parser, DIG (dynamic initial gain) and CFO (center frequency offset)
settings.
