Module Name:    src

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

Log Message:
- Fix availability detection of WoL on some chips. This change has no effect
other than dmesg because WM_F_WOL is currently not used to change the behavior:
  - For ICH/PCH, check the capability not from NVM but from the WUC register.
    Check the value before clearing the register.
  - 82580 and newer have per-port NVM block, so read the area correctly.
    Note that 82580, I350 and I354 may have PCI function 2 and 3.
  - Some devices can't detect WoL capability neither from NVM nor from WUC.
    Use PCI device ID and the function number.
- Print the WUS (WakeUp Status) register bits when resume.
