From 628639b1c976a5f02792dc6595a4d199b7b70d85 Mon Sep 17 00:00:00 2001 From: Dedy Lansky Date: Wed, 8 Mar 2017 13:52:17 +0200 Subject: [PATCH] wil6210: use WMI_DISCONNECT_CMDID upon connect timeout Upon connect timeout driver invokes _wil6210_disconnect() which iterates over sta array and disconnects each connected sta. In practice, because the connection is still ongoing and because cid is not yet allocated, disconnect is not actually happening. This leaves FW in connecting state while driver is in disconnected state. To fix this, upon connect timeout, explicitly send WMI_DISCONNECT_CMDID to FW to make sure it gets disconnected.
