Subject: [PATCH 5/8] wifi: rtw89: fw: propagate an argument include_bb for BB MCU firmware
Date:   Fri, 1 Sep 2023 14:15:04 +0800
Message-ID: <20230901061507.34312-6-pkshih@realtek.com>
In-Reply-To: <20230901061507.34312-1-pkshih@realtek.com>

Precedence: bulk

Though WiFi 7 chips need BB MCU firmware, we don't download it in probe
stage. Instead, only bring interface up under normal operation or WoWLAN
mode. So, add an argument to assist download flow to setup download
settings properly.
