CVS commit: src/sys/dev/pci

Module Name:    src
Committed By:   cegger
Date:           Wed Aug  5 12:07:16 UTC 2009

Modified Files:
        src/sys/dev/pci: if_age.c

Log Message:
- Don't access VPD even if hardware advertised the capability.
  It seems that some revisions of the controllers hang while accessing
  the VPD. Because VPD access routine is now unused, nuke it.
- Let TWSI reload EEPROM if VPD capability is detected. Reloading
  the EEPROM will also set the Ethernet address, so age(4) now reads
  AGE_PAR0 and AGE_PAR1 register to get the Ethernet address. This removes
  removes a lot of hacks and enhance readability a lot.
- Double PHY reset timeout as it takes more time to take the PHY out of
  power-saving state.
- 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 thing done by the
  Linux driver.
- Don't rely on auto-clearing feature of master reset bit, just wait
  1ms and check idle status of MAC.
