We have the same issue. We have 30 Huawei servers with Intel X710 card and vsphere 6.5 u1 patch2. VM network connections on a Distributed Virtual Switch seem to freeze after this error appears in vmware logs:

After this, multiple Dvs ports fail and packets are dropped (vmnic1: dropped 501 pkts from queue).
This has happened on 3 ESXi servers already, causing downtime on VMs.
The logs show the same sequence of events on all 3 servers:
Only way to recover the VM networking is to vMotion to a different host.
I am attaching the vmkernel log file for this server. Issues start at 2018-03-30T07:35:50.216Z
We are really DESPERATED... We are working in big migration project and we are totally frozen!!!
We have tried to installed the last drivers "1.5.8" and the issue happends again.
NEED URGENT HELP!!!
Thank you for the post and I am sorry to hear what happened. Please share where did you download the driver for the X710 network card? Please provide the link.
Driver link: https://my.vmware.com/web/vmware/details?downloadGroup=DT-ESXI65-INTEL-I40EN-158&productId=614 https://my.vmware.com/web/vmware/details?downloadGroup=DT-ESXI65-INTEL-I40EN-158&productId=614https:... https://my.vmware.com/web/vmware/details?downloadGroup=DT-ESXI65-INTEL-I40EN-158&productId=614
Thank you for the information. Are these X710 network card Intel retail unit or OEM model?
For Intel retail version, you can check Board # (PBA) at this website https://www.intel.com/content/www/us/en/support/articles/000005612/network-and-i-o/ethernet-products... List of Supported Retail Intel® Ethernet Adapters
If the NICs are OEM, they will have different Board# (PBA).
Or you can follow the Identify your adapter PCI Device ID in the website to check the Vendor and Device ID.
Really appreciate your comments...
Anyway when have you planned to release a new version for this driver that works with vsphere 6.5 U1?
Or do you have no notice of the issues of this card with another customers since several months ago?
I am also experiencing the same issue with the driver putting the port into a failed mode (causing ESX top drop 100% of the packets on that nic)
ESXi 6.5 U1, 7967591

We have also tried different HP firmware and driver levels. We are using the HP 562SFP+ and 562FLR-SFP+ cards (based on the Intel X710 chip).
Digging around I found this in the release notes from the Intel driver package:
In a virtualized environment, on Intel(R) Server Adapters that support SR-IOV,
the virtual function (VF) may be subject to malicious behavior.
Software-generated frames are not expected and can throttle traffic between the
host and the virtual switch, reducing performance. To resolve this issue,
configure all SR-IOV enabled ports for VLAN tagging. This configuration allows
unexpected, and potentially malicious, frames to be dropped.
I do have some options on our HP DL380 Gen10 servers that may fix the driver failing but we will not be able to additional testing for a few days at least. I wanted to see if you have tried either enabling VLAN support for the NIC in the UEFI/BIOS or turning off SR-IOV entirely for the NIC/SYSTEM from the UEFI/BIOS?
Further checking, the information I received is Malicious Driver Detection is and open issue for ESX i40en driver version 1.5.8. The Malicious Driver Detection issue that we are aware of will be addressed in the next i40en driver release. The next driver is going through VMware Certification process and expected to release in a couple of weeks. We will have an official statement on this issue by next week. Thank you for your patience on this matter.
