vnic's for in guest iscsi

I have VM's on VMware that I am setting up in-guest iSCSI.  These guest iSCSI NIC's are riding the same real NIC's on the VMware Host that is used for iSCSI from VMware to the Nimble.

 

I give each VM two vnic's for iSCSI so I can use MPIO.  My question is does Nimble have a recommendation for the vnic settings in the Windows VM?

 

I turned ON Jumbo frames since my physical network from the VMware host is using Jumbo frames.  What about all of the TCP Off Load options in the vnic's?  Or RSS?

 

From my previous Windows/Hyper V experience everyone and their brother recommended that TCP Off load options be turned OFF as it could cause performance issues with iSCSI.  That was for a physical Windows host and in the case of Hyper V VM's a "good idea" from most blog's I read back when we had Hyper V

 

Thanks for any input!
