MFC r213081,213225,213280:
r213081:
  Always show asic/chip revision in device attach phase. There are
  too many bge(4) controllers there and model name does not
  necessarily match asic/chip revision. Relying on VPD string made
  it hard to identify exact asic/chip revision so the first step to
  debug bge(4) was getting exact asic/chip information with verbose
  boot which may not be available on production server.

r213255:
  Set the number of RX frames to receive after RX MBUF low watermark
  has reached. This reduced number of dropped frames when
  flow-control is enabled. Previously it dropped incoming frames once
  RX MBUF low watermark has reached. The value used in MAC RX MBUF
  low watermark is greater than or equal to 4 so receiving two more
  RX frames should not be a problem.

  Obtained from:	OpenBSD

r213280:
  After r207391, brgphy(4) passes resolved flow-control settings to
  parent driver. Use that information to configure flow-control.
  One drawback is there is no way to disable flow-control as we still
  don't have proper way to not advertise RX/TX pause capability to
  link partner. But I don't think it would cause severe problems and
  users can selectively disable flow-control in switch port.
