I was not able to attend the Linux conference held at the end of August
myself but coworkers of mine here at Intel informed that method 2 here
seems to be the preferred approach.  Perhaps some folks who attended
the the conference can chime in with more specifics.

There really wasn't much more specific discussion.  Bjorn's summary of
the mini-summit <http://lwn.net/Articles/514113/> says:

SR-IOV Management

    Currently drivers implement module parameters like "max_vfs".  This means
    all devices claimed by the driver get the same number of VFs, and you can't
    change anything without unloading and reloading the driver.

    Consensus that we should try to implement a knob for this in sysfs so it
    can be generic (not in each driver) and set individually for each device.

I don't think any implementation has been posted to the linux-pci list

please check attached three patches...
