Subject: [PATCH] wcn36xx: set PREASSOC and IDLE stated when BSS info changes
Git-commit: 2a46c829a9266bf2a2be1a3d25dbac5fcd4eb9c1
Patch-mainline: v4.18-rc1
References: FATE#326906
When a BSSID is joined, set the link status to 'preassoc', and set it to
'idle' when the BSS is deleted.
This is what the downstream driver is doing, and it seems to improve the
reliability during connect/disconnect stress tests.
