Hi, I am not sure if this is the correct mailer but I see an issue that seems to indicate a bug in i40evf behaviour or the VF-PF interaction. Kindly point me to the correct mechanism to report this.
Stock CentOS 7.5 VM on a VMWARE ESX 6.7U3 host w/ X710 w/ SR-IOV I get these error messages in the VM i40evf 0000:0b:00.0: PF returned error -4 (I40E_ERR_CONFIG) to our request 27 27 is VIRTCHNL_OP_ENABLE_VLAN_STRIPPING. Turns out, this was happening when I was doing ethtool -K gro off. Should that be the case? The ESX host PF driver (i40en) does not seem to allow VLAN HW stripping offload if the vswitch is in VST (VLAN configured in vswitch). And thus the error is justified, but I was not trying to change the VLAN offload setting, in the first place.
