When I added the SR-IOV support for the 82576 adapter I removed a call to set the MAC type in an early routine, thinking it was unnecessary, since a slightly later shared code init does the same thing. I also saw no problem when I did this on the 82576.... well, it did have a bad effect that I did not notice, the slightly later call, igb_setup_msix() did not have the mac set and this resulted in the 82575 creating more queues than it is really able to handle. So, bottom line, this is a critical fix for 82575: SVN rev 210968 Cheers, Jack
