From 87dc02551c509703123a60dd7f043d75e92a6aed Mon Sep 17 00:00:00 2001 From: Saeed Mahameed Date: Fri, 4 Nov 2016 01:48:42 +0200 Subject: [PATCH] net/mlx5e: Fix XDP error path of mlx5e_open_channel() In case of mlx5e_open_rq fails the error handling will jump to label err_close_xdp_sq and will try to close the xdp_sq unconditionally. xdp_sq is valid only in case of XDP use cases, i.e priv->xdp_prog is not null. To fix this in this patch we test xdp_sq validity prior to closing it. In addition we now close the xdp_sq.cq as well.
