  SVN rev 218788 on 2011-02-18 02:58:09Z by yongari
  
  Apply special PHY initialization code for 21143 controllers before
  any other media configuration. Otherwise some 21143 controller
  cannot establish a link. While I'm here remove the PHY
  initialization code in dc_setcfg(). Since dc_setcfg() is called
  whenever link state is changed, having the PHY initialization code
  in dc_setcfg() resulted in continuous link flips.
  After driver resets SIA, use default SIA transmit/receive
  configuration instead of disabling autosense/autonegotiation.
  Otherwise, controller fails to establish a link as well as losing
  auto-negotiation capability. For manual media configuration, always
  configure 21143 controller with specified media to ensure media
  change. This change makes ANA-6922 establish link with/without
  auto-negotiation.
  
  While I'm here be more strict on link UP/DOWN detection logic.
  
  Many thanks to marius who fixed several bugs in initial patch and
  even tested the patch on a couple of dc(4) controllers.
