The hardware can behave differently for a given feature and the igb drivers supports a different set of hardware than e1000e. For igb, we support 82575 and greater (82576, 82580, i350). The best bet is the Datasheet for the 825XX you're working with. Here's the datasheet for 82580. http://download.intel.com/design/network/datashts/321027.pdf. I'll take a look at your patch and the datasheet as well and see if I can find anything to help.
