The zephyr driver sets the scan_res2_get_in_prog flag to true after starting to get the results. This can cause possible race as the results might be done before the dev_ops->get_scan_results2() returns. This could lead to timeout in the following while loop.

Please raise a manifest PR and this should be nrf noup as our upstream is still hostap.git not zephyrrtos

Is the manifest changes really needed yet, the original fix is not yet merged and we do not reference that zephyrrtos repo yet in any manifest.

Yes, the manifest for sdk-hostap needs to be updated in sdk-nrf to pull this fix to NCS. Once the zephyrrtos/sdk-hostap is mature then we need to rebase this repo to use that as a upstream.
