From: Noa Osherovich Date: Sat, 4 Jun 2016 12:15:29 +0000 (+0300) Subject: IB/mlx5: Return PORT_ERR in Active to Initializing tranisition X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2788cf3bd90af3791c3195c52391bcf34fa67b40;p=linux-beck.git IB/mlx5: Return PORT_ERR in Active to Initializing tranisition FW port-change events are fired on Active <-> non Active port state transitions only. When the port state changes from Active to Initializing (Active -> Down -> Initializing), a single event is fired. The HCA transitions from Down to Initializing unless prevented from doing so, hence the driver should also propagate events when the port state is Initializing to consumers so they'll be aware that the port is no longer Active and act accordingly.
