Changes to update driver with latest Intel driver version 2.1.7
- Changed from using explicit devices id to using descriptive labels.
- Added support for 82573 and 82546 Quad adapters.
- Corrected support for 82547EI and 82541ER (mac_type was not assigned)
- Removed #ifdef DBG_STATS and extraneous code.
if_em_hw.c/if_em_hw.h
- Added support for 82573 and 82546 Quad adapters.
- Brought forward Intel's most current mac and phy changes.
