Pull up the following, requested by msaitoh in tickt #1085:
sys/dev/mii/inbmphyreg.h 1.11
sys/dev/pci/if_wmreg.h 1.108
sys/dev/pci/if_wm.c 1.590-1.596 via patch
- 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.
