To: kvalo; +Cc: phhuang, linux-wireless
From: Po-Hao Huang <phhuang@realtek.com>
Adding this supports beacon filter and connection quality monitor.
To make host CPU wake up less, let firmware perform signal
monitoring and beacon processing, then notify driver upon signal
changes or beacon loss.
This feature needs firmware 0.27.56 or newer to support it.

From: Po-Hao Huang <phhuang@realtek.com>
Allocate a per-skb completion to track those skbs we are interested in
and wait for them to complete transmission with TX status. To avoid
race condition between process and softirq without additional locking,
we use a work to free the tx_wait struct later when waiter is finished
referencing it. This must be called in process context and with a
timeout value greater than zero since it might sleep.
We use another workqueue so works can be processed concurrently and
when the PCI device is removed unexpectedly, all pending works can be
flushed. This prevents some works that were scheduled but never processed
leads to memory leak.

From: Po-Hao Huang <phhuang@realtek.com>
Add support of remain on channel ops. Since channel context is
required to enable multi-channel concurrent(MCC) and the current
ROC in mac80211 don't support more than 1 channel context, add this
to let P2P and other protocols relying on this work as expected.
The off-channel duration and cancel timing is purely controlled by
upper layers.

From: Ping-Ke Shih @ 2023-03-16 12:18 UTC (permalink / raw)
To: kvalo; +Cc: phhuang, linux-wireless
From: Po-Hao Huang <phhuang@realtek.com>
Use POWER_ON flag to make sure power on/off is symmetric. Since both
remain_on_channel and hw_scan both alter the power state, this makes
sure that we don't enter/leave IPS mode twice.
Also, replace IPS related functions with inline function that does
similar logic so we can track it more easily.

From: Po-Hao Huang <phhuang@realtek.com>
We used to store operating channel info after associated. However, scan
might happen before that. Without switching back to operating channel,
authentication or association might fail. Therefore, we switch back to
operating channel when the scanning vif's BSSID is non-zero, which
implies connected or during attempt to connect.
