Subject: iwlwifi: mvm: Increase the scan timeout guard to 30 seconds
From: Ilan Peer <ilan.peer@xxxxxxxxx>
commit ced50f1133af12f7521bb777fcf4046ca908fb77 upstream.
With the introduction of 6GHz channels the scan guard timeout should
be adjusted to account for the following extreme case:
- All 6GHz channels are scanned passively: 58 channels.
- The scan is fragmented with the following parameters: 3 fragments,
95 TUs suspend time, 44 TUs maximal out of channel time.
The above would result with scan time of more than 24 seconds. Thus,
set the timeout to 30 seconds.
