        src/sys/dev/pci: if_wm.c if_wmreg.h

Log Message:
- Control TX/RX descriptor snooping control bits on ICH8 and newer.
  Only on ICH8, No-snoop bits are opposite polarity. On my Thinkpas X61,
  the default value of this bits are all zero, so this commit changes
  the snoop function enable on the machine. I tested with some other
  PCH machines and those bits are all zero (enable snoop by default),
  so this commit won't affect to some machines.
- Disable relax ordering on 82546GB(Device ID 0x1099 and 0x10b5) or >= ICH8.
  Same as other OSes.
