      Overview
      – 1000 Mbps IEEE 802.3z TBI
      – 10/100/1000 Mbps RGMII/RTBI
      — Full- and half-duplex support
      — Buffer descriptors are backwards compatible with MPC8260 and MPC860T 10/100
      programming models
      — 9.6-Kbyte jumbo frame support
      — RMON statistics support
      — 2-Kbyte internal transmit and receive FIFOs
      — MII management interface for control and status
      — Programmable CRC generation and checking
      OCeaN switch fabric
      — Three-port crossbar packet switch
      — Reorders packets from a source based on priorities
      — Reorders packets to bypass blocked packets
      — Implements starvation avoidance algorithms
      — Supports packets with payloads of up to 256 bytes
      Integrated DMA controller
      — Four-channel controller
      — All channels accessible by both local and remote masters
      — Extended DMA functions (advanced chaining and striding capability)
      — Support for scatter and gather transfers
      — Misaligned transfer capability
      — Interrupt on completed segment, link, list, and error
      — Supports transfers to or from any local memory or I/O port
      — Selectable hardware-enforced coherency (snoop/no-snoop)
      — Ability to start and flow control each DMA channel from external 3-pin interface
      — Ability to launch DMA from single write transaction
      PCI Controllers
      — PCI 2.2 compatible
      — One 64-bit or two 32-bit PCI ports supported at 16 to 66 MHz
      — Host and agent mode support, 64-bit PCI port can be host or agent, if two 32-bit ports, only one
      can be an agent
      — 64-bit dual address cycle (DAC) support
      — Supports PCI-to-memory and memory-to-PCI streaming
      — Memory prefetching of PCI read accesses
      — Supports posting of processor-to-PCI and PCI-to-memory writes
      — PCI 3.3-V compatible
