Hi. I guess this is a "known" issue, because there is some kind of "errata" about this. BUT, as you did notice, my motherboard is Intel DQ67EP, and i do have latest bios installed. And, still, my network card is suffering from this bug. So, my board vendor does know about issue, but oddly, they are not able to fix this!?? In any case, i do believe that this will be fixed in bioses eventually, BUT until this happens, this "fix" is necessary. So, i would ask again that this fix is included in driver. It must not be "enabled" by default, but to be able to enable it via option is just fine.
