VMWare, Direct Path fix ?

I get the following error on Host->Config->Advanced Setting for a NIC

Direct Path I/O Configuration

  Warning:  Configuration host hardware without virtualization features for virutal machine
  passthrough will make it unavailable for use except for dedicating it to a single virtual
  machine.  In particular, configuraing a device needed for normal host boot or operation
  can make normal host boot impossible and may require significant effort to undo.

Select allOpen in new window

While I am tyring to get it to work for PassThru to have the knowledge of how to do that, my goal is to virtualize the card

I installed VMTools on all my VM's, and rebooted the host, hoping that would give me the driver required to make this work

However, I still get a Direct Path issue

My NIC is a Broadcom Corporation NetXtreme II5770 10Gigabit Ethernet

My machine is a Intel Westmere EP 12 core machine

What do I do next ?

BTW,  VMWare knows what the NIC is (Broadcom 5710), and that is checked in Advanced Settings, and on another machine the card is working just fine on VMWare without the need to install a driver.

Is installing a driver the correct course, and if so what should I do next

Thanks
