Another question unrelated to this series:
Does 82540EM still supported by Win2k12?
The following link shows that 82540EM were not supported in Win2k12.
https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProdId=983

The oldest 825x card supported by 2k12 seems 82574.

If yes, workaround a buggy driver may be endless work in the future.
