MFC r253481:
  Recognize BCM5725C PHY.
MFC r253483:
  Add support for upcoming BCM5725 (ASIC 5762) controller.  This is a
  new 1Gb server controller chip that will be going into production
  soon.
  BCM5725 combines MAC with triple-speed PHY, a Network Controller
  Sideband Interface (NC-SI) and on-chip memory buffer in a single
  device.  BCM5725 has an Application Processing Engine (APE) that is
  capable of on-chip management and offloading features.  BCM5725
  supports high-precision clock, time stamp registers for
  receive/transmit packets and programmable trigger inputs and
  watchdog timeouts. These new features are not yet supported by
  bge(4).
  Many thanks to Broadcom for continuing to support FreeBSD!
MFC r253540:
  5725 family of devices corrupts TSO packets when TSO DMA buffers
  cross into regions which are within MSS bytes of a 4GB boundary.
  If we encounter the condition, drop the packet.
MFC r258830:
  Add support for BCM57764, BCM57767, BCM57782, BCM57786 and BCM57787.
