For software-driven scan, rely on mac80211 software scan instead
of internal driver implementation. The internal implementation
cause connection trouble since it keep the antenna busy during
the entire scan duration, moreover it's only a passive scanning
(no probe request). Therefore, let mac80211 manages sw scan.
Note: we fallback to software scan if firmware does not report
scan offload support or if we need to scan the 5Ghz band (currently
not supported by the offload scan...).

What changed since v2? Please always include a changelog so that I
don't
need to guess what you have changed in the patch. No need to resend, a
reply is enough.
Yes sorry, this patch has been rebased on ath master and squashed with
Bryan's fix:
wcn36xx: Set sw-scan chan to 0 when not associated
No additional changes have been made on top of the initial patches.

Loic
This is excruciatingly slow on Android.
Android I'm finding unlike Debian where this stuff was tested, merrily
issues scan requests every 30 seconds.
For me this ends up looking like this

Basically it takes 15 seconds to complete.
Interleaved scan seems very slow and is IMO unusable on Android
The software scan is driven by mac80211 which interleaves channels
scanning
with the regular data operations. In worst case, it scans during 111ms
on the
channel and switches back to the operating channel for 200ms.
So, with 35 channels to scan that would take about 11 seconds to
complete...
So yes, it's quite slow...
Yes looks a scheduling thing in mac80211.
However, one remaining
thing to try would be to send an update-channel-list command to the
firmware before each offload scan (cf UPDATE_CHANNEL_LIST_REQ
in the downstream driver). That's not something I've tried yet.
I've tried
1. Setting the operating frequency to a 5ghz band before the scan
2. Updating the channel list with 2g/5g channels via
UPDATE_CHANNEL_LIST_REQ
3. Updating the channel list with 5g only with UPDATE_CHANNEL_LIST_REQ
4. Doing 5g channels only in the channel list of
WCN36XX_HAL_START_SCAN_OFFLOAD_REQ
I don't think the channel list matters, if I recall rightly I've also
tried leaving out the channel list in WCN36XX_HAL_START_SCAN_OFFLOAD_REQ
and get back the same set of channels in the result
I guess we should take this patch anyway, since it makes wcn36xx and
mac80211 agree on ownership of the antenna...

Ah.
If we implement ops->flush() we can slash that idle time down significantly
static void ieee80211_scan_state_resume(struct ieee80211_local *local,
unsigned long *next_delay)
{
if (local->ops->flush) {
ieee80211_flush_queues(local, NULL, false);
*next_delay = 0;
} else
*next_delay = HZ / 10;
}
Trivial hack example:
+void wcn36xx_flush(struct ieee80211_hw *hw, struct ieee80211_vif *vif,
+ u32 queues, bool drop)
+{
+}
+
static const struct ieee80211_ops wcn36xx_ops = {
.start = wcn36xx_start,
.stop = wcn36xx_stop,
@@ -1187,7 +1192,7 @@ static const struct ieee80211_ops wcn36xx_ops = {
.sta_add = wcn36xx_sta_add,
.sta_remove = wcn36xx_sta_remove,
.ampdu_action = wcn36xx_ampdu_action,
-
+ .flush = wcn36xx_flush,
CFG80211_TESTMODE_CMD(wcn36xx_tm_cmd)
};
That ~ 20 seconds is cut to just 4 ! Which to be fair seems to be the
kind of time it took to do the old version of the software scan.

Not only that but I get the full scan-result list as expected...
So yeah I think this patch is good as-is.
We should add ops->flush() - I guess I'll send something out for comment
on that in the next 12-18 hours.
