Teaming and VMQ issues with broadcom based network cards on Microsoft OS

We've had countless issues with poor performance, inconsistent performance, dramatic packet loss when using HP530T Nics (BCM957810A1008G) on Windows based OS (bare-metal) when using the teaming option. This as made the system team reluctant to use teaming and as been leading to bad architecture designs.

Microsoft rep says it's common knowledge that these Broadcom based chipset NICs experience issues under MS windows operating system. We've tried different teaming solutions within windows, we've tried different drivers and issues are never fully resolved on windows server 2008-2012-2016.

We've ordered Intel based Nics to see if issues will be resolved.

When the teaming is removed, all issues disappear.

We don't see any issue with the teaming when the cards are in a VMware ESX server.

It's been hard for the network team to help diagnose the issue as we don't have access to the servers and the system team as been reluctant to install Wireshark on the production servers that are experiencing the issue. The problems are also very intermittent. One of the main issue is the application crashing when creating a collection of VMs on Hyper-V based VDI.

As anyone encountered teaming issues when using Broadcom chipset based NICs? Did you ever resolve it ?
