VMXNET3 and Exchange 2016

According to HealthChecker in our Exchange, the script is warning us that ("Large packet loss at the guest operating system level on the VMXNET3 vNIC in ESXi (2039495)). I do not see any connectivity issues. There is a KB article from VMware to look at the firmware to see if they are okay, then change the buffer size. I do not want to change the buffer size since I do not see any connectivity issues. Has anyone else seen this warning in their Exchange Server/SQL environment? Is this a real problem? Or can it be ignored?
