10Gb ISCSI NICS - enable VMQ in W2012R2 for best ISCSI performance?

We had an issue with our 10Gb NICS LAN Team NICS in W2012R2. It is now solved by setting the base and max number of processors to be used. 

While reading up on VMQ I am reading MS best practise advice to enable VMQ also on ISCSI  MPIO NICS for best performance in Windows Hyper-V Failover Cluster. It is enabled by defauilt on the NIC driver but with Get-NetAdapterVmq I see that is not enabled in Windows for the Nimble ISCSI ports. Get-NetAdapaterRSS RSS is enabled and to use all physical processors incuding node0.  

What does the Nimble connection manager by default do with RSS and VMQ settings? Best practise on Hyper-V Failover clustyer hosts?

TIA,

Fred
