From: Ilan Peer Date: Fri, 10 Dec 2021 07:06:21 +0000 (+0200) Subject: iwlwifi: mvm: Increase the scan timeout guard to 30 seconds X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ced50f1133af12f7521bb777fcf4046ca908fb77;p=linux.git iwlwifi: mvm: Increase the scan timeout guard to 30 seconds 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.
