  SVN rev 213495 on 2010-10-06 21:23:57Z by yongari
  
  Add more comments to rings supported by the controller. Different
  versions of controller support different number of ring control
  blocks such that adjust code a bit to access known number of
  send/receive ring control blocks. Previously bge(4) blindly
  accessed 16 send/receive RCBs. Also move initializing standard
  receive producer ring producer index, jumbo receive producer ring
  producer index and mini receive producer ring producer index to
  the end of each receive producer ring initialization.
  
  Do not assume mini receive producer ring is available only when
  controller has jumbo frame capability, instead explicitly check
  ASIC version BCM5700 to disable mini receive producer ring.
  
  Additionally always enable send ring 0 regardless of controller
  versions. Previously bge(4) didn't enable send ring 0 if controller
  is BGE_IS_5705_PLUS. Becase bge(4) need 1 send ring to send frames
  at least, I have no idea how it would have worked so far.
