Subject: iwlwifi: mvm: Fix command queue number on d0i3 flow
From: Haim Dreyfuss <[email protected]>
[ Upstream commit c72c37b7f392ad7edc10b6092fa48c632ba6f4ed ]
During d0i3 flow we flush all the queue except from the command queue. Currently, in this flow the command queue is hard coded to 9. In DQA the command queue number has changed from 9 to 0. Fix that.
This fixes a problem in runtime PM resume flow.
