SQL iSCSI LUN - Best practice configuring network interfaces

Hi, we have a few SQL servers both physical and virtual and on the SQL end there are reports of very long waits at times but from the netapp the response time is showing as sub-millisecond (FAS8020 cluster). Does anyone have a NIC config best practice for connecting a QLOGIC BCM57800 to the FAS.

 

Storage network is all 10Gbps and jumbo frames is enabled but I wonder about the other NIC config settings like flow control and TCP offload among other settings.

 

Any help would be appreciated, none of the documentation I have found relates to using iSCSI.

 

Thanks
