Subject: [PATCH 073/146] iwlwifi: mvm: fix fw monitor 7000 HW recollecting
Git-commit: 3e73148406c67615bbe8d166d2c22efc3995e305
Patch-mainline: v4.13-rc1
References: FATE#322675
To stop and start the FW monitor in the 7000 HW
family we need to use a different bit, otherwise
after stopping it for the first time - it won't
get restarted. Use the correct bitmask.
Note: This fix is only for DRAM collection mode.
For other modes, an additional fix will be
needed.
