Sync up to Intel's latest FreeBSD em driver (6.2.9). Adds support
for a few newer Intel PCIe boards, some code removal and cleaning
and a few bug fixes.
From: Jack Vogel@Intel
Tested by mk@ wilfried@ brad@ dlg@, Marc Winiger, Gabriel Kihlman,
Jason Dixon, Johan Mson Lindman, and a few other end users.
Tested with 82543, 82544, 82540, 82545, 82541, 82547, 82546 and 82573.
