+       - 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.
