YES!!!!

 

We were able to get this problems solved by the following:

 

On the R710 host with the 8152 CNA card do the following:

 

1.  Disable the MSIX capability

 

    esxcli system module parameters set -m qla2xxx --parameter-string "ql2xenablemsix=0"

2. Change the network packet pool size

 

    In vCenter, navigate to the affected Host. Choose Configuration, Choose Advanced Settings under System. Find VMkernel.Boot.netPktPoolMaxSize and change it from 656 to 800.

3.  Finally, the Most critical change is to double the netPktHeapMaxSize.

 

   In vCenter, navigate to the affected Host. Choose Configuration, Choose Advanced Settings under System, Change the value of VMkernel.Boot.

netPktHeapMaxSize (under the VMkernel section of Advanced Settings) from 64 to 128
This instruction came from our open ticket with tech support.  We were able to validate that this resolved the problem on our affected hosts.
