        sys/dev/pci/if_wm.c: revision 1.686

        sys/dev/pci/if_wm.c: revision 1.688
        sys/dev/pci/if_wm.c: revision 1.689

s/ressource/resource/. Found by knakahara.

  Add new flag named WM_F_CRC_STRIP and use it. No functional change.

  This change also sets the RCTL_SECRC bit on I211 but it doesn't change
the behavior because I211 always strips CRC like I35[04] and I210.

  Add a workaround for jumbo frame on PCH2 and newer. Tested by chs@.

- Add wm_lv_jumbo_workaround_ich8lan() and use it. From FreeBSD.
   XXX For KUMCTRLSTA_OFFSET_HD_CTRL register modification, it's doubtful.
   FreeBSD and Linux do the same thing that they set the same value on both
   jumbo frame's enable case and the disable case. It seems the default value
   is 0x0b0c and it's not changed on the enable case, so it might be a bug
   on the enable case or the modification is not required.
- Rename I219_UNKNOWN1 to I82579_UNKNOWN1.
  Use 12K for packet buffer for jumbo frame on PCH2 and newer.

XXX Note that Linux Use 14K.
