Subject: [PATCH v6 08/24] rtw89: implement mac80211 ops
Date: Fri, 20 Aug 2021 12:35:22 +0800	[thread overview]
Message-ID: <20210820043538.12424-9-pkshih@realtek.com> (raw)
In-Reply-To: <20210820043538.12424-1-pkshih@realtek.com>

Implement ops to interactive with mac80211. The ops contain start/stop,
TX, add/remove vif, config, sta state, key, ampdu action,
sw_scan_start/complete, and so on. To avoid racing between ieee80211
delayed work and ioctl, all of them are protected by rtwdev->mutex.
To yield better TX performance, wake TX queue is implemented.
