It seems that some revision of controller hang while accessing the VPD. Because VPD access routine are unused, nuke it. o Let TWSI reload EEPROM if VPD capability is detected. Reloading EEPROM will also set ethernet address so age(4) now reads AGE_PAR0 and AGE_PAR1 register to get ethernet address. This removes a lot of hack and enhance readability a lot. o Double PHY reset timeout as it takes more time to take PHY out of power-saving state. o Explicitly check power-saving state by checking undocumented PHY registers. If link is not up, poke undocumented registers to take PHY out of power-saving state. This is the same way what Linux does. On resume, make sure to wake up PHY. o Don't rely on auto-clearing feature of master reset bit, just wait 1ms and check idle status of MAC. o Add PCI device revision information in bootverbose mode. This should fix occasional controller hang in device attach phase. Reported by: barbara < barbara.xxx1975 at libero DOT it > Tested by: barbara < barbara.xxx1975 at libero DOT it > |
