Log Message:
Pull up the following revisions(s) (requested by msaitoh in ticket #1648):
        sys/dev/mii/inbmphyreg.h                1.11
        sys/dev/pci/if_wm.c                     1.586-1.588, 1.590-1.596 via patch
        sys/dev/pci/if_wmreg.h                  1.108

- rename tu event counter to txunderrun.
- Try m_defrag() to reduce the number of DMA segment if bus_dmamap_load_mbuf()
   returned EFBIG. When m_defrag() is called, txqNNdefrag event counter is
   incremented. If the 2nd try of bus_dmamap_load_mbuf() failed, txqNNtoomanyseg
   event counter is incremented.
- Reduce the max number of DMA segments from 256 to 64 (it's the same value
   as other BSD's (EM_MAX_SCATTER) and more than before if_wm.c rev. 1.75's
   value (40)) because we do m_defrag() now.
- 82574 and newer document says the status field has neither EC
   (Excessive Collision) bit nor LC (Late Collision) bit (reserved), so
   don't check the bit.
- Add workaround for DMA hang problem which result in TX device timeout
   on PCH_LPT with I218. Same as FreeBSD and Linux. This workaround is
   only for device ID 0x155a, 0x15a2, 0x1559 and 0x15a3.
- Fix a PCH2 specific bug that wrong PHY register value can be read
   when boot. Same as FreeBSD and Linux.
- After writing MDIC register, don't read quickly the same register but
   do delay(50). Same as other OSes.
- Add missing wm_gate_hw_phy_config_ich8lan(false) in
   wm_phy_post_reset() on PCH2. wm_gate_hw_phy_config_ich8lan(true) is
   called in wm_reset(), so wm_gate_hw_phy_config_ich8lan(false) should
   be called after reset in wm_phy_post_reset().
- On PCH2, set the phy config counter to 50msec after (PHY) reset.
- KNF & Use macro.
