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

Log Message:
fix EITR setting.

    + 82574
      - add EITR setting, that is MSI-X mode interrupt interval
    + 82575
      - fix EITR value. 82575's EITR usage is the same as legacy (not NEWQUEUE)
        controllers
      - apply workaround which 82575's EITR does not have CNT_INGR bit
    + other NEWQUEUE controllers
      - fix interrupt interval field. NEWQUEUE (include 82575) controllers'
        interrupt interval field is 2:14
      - use CNT_INGR bit which avoid to overwrite counter

tested 82574, 82575 and I354.
