Subject: [PATCH AUTOSEL 6.6 19/35] wifi: iwlwifi: mvm: properly set 6 GHz channel direct probe option

From: Ayala Beker <ayala.beker@...el.com>

[ Upstream commit 989830d1cf16bd149bf0690d889a9caef95fb5b1 ]

Ensure that the 6 GHz channel is configured with a valid direct BSSID,
avoiding any invalid or multicast BSSID addresses.
