Subject: iwlwifi: mvm: set SSID bits for passive channels
From: David Spinadel <david.spinadel@xxxxxxxxx>
commit bb963c4a43eb5127eb0bbfa16c7a6a209b0af5db upstream.
Set SSID bitmap for direct scan even on passive channels,
for the passive-to-active feature. Without this patch only
the SSID from probe request template is sent on passive
channels, after passive-to-active switching, causing us to
not find all desired networks.
Remove the unused passive scan mask constant.
