Message-Id: <20180830211147.17008-13-jeffrey.t.kirsher@intel.com> Date: Thu, 30 Aug 2018 14:11:44 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Patryk Małek <patryk.malek@...el.com>, netdev@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jogreene@...hat.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next v2 12/15] i40evf: Don't enable vlan stripping when rx offload is turned on From: Patryk Małek <patryk.malek@...el.com> With current implementation of i40evf_set_features when user sets any offload via ethtool we set I40EVF_FLAG_AQ_ENABLE_VLAN_STRIPPING as a required aq which triggers driver to call i40evf_enable_vlan_stripping. This shouldn't take place. This patches fixes it by setting the flag only when VLAN offload is turned on.
