From 1c25103326f9e94c9adade33da09ac772a1e59a2 Mon Sep 17 00:00:00 2001 From: Kalesh AP Date: Thu, 16 Jan 2020 18:34:51 +0530 Subject: [PATCH] net/bnxt: handle HW filter setting when port is stopped Driver destroy the VNIC when the port is brought down. Port HW filter setting such as promiscuos, allmulti and VLAN filtering will be applied when port is started. Fixed to return success silently for these callbacks when port is stopped. Also fixed to clear "bp->dev_stopped" before invoking bnxt_vlan_offload_set_op() in bnxt_dev_start_op().
