Solaris 11 igb driver question

I was wondering if anyone knew how to tune the Intel igb driver to get more performance out of gigabit?

available parameters are:

tx_ring_size (default 512) The number of the transmit descriptors per receive queue
rx_ring_size (default 512) The number of the receive descriptors per receive queue
mr_enable (default 0) Enable multiple rx queues and tx queues
group_number (default 1) The number of the receive ring groups


I checked the oracle support site and it says that a mr_enable of 0 actually will enable the multiple queues. This seems pretty counter-intuitive and I was wondering if anyone knew how to check if multiple queues were indeed enabled and working?

I'm trying to tune this system for a NAS purpose, large file serving only. Should I max out these options?
