Subject: [PATCH] iwlwifi: mvm: Increase the scan timeout guard to 30 seconds
Git-commit: ced50f1133af12f7521bb777fcf4046ca908fb77
Patch-mainline: v5.17-rc1
References: git-fixes

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.
