It uses a single Management interface + to manage the two physical connection devices (PHYs). Each Ethernet port + has its own statistics monitor that tracks and reports key interface + statistics. Each port supports a 256-entry hash table for address + filtering. In addition, each port is bridged to the Switch Fabric + through a 2-Kbyte transmit FIFO and a 4-Kbyte Receive FIFO. + + Each Ethernet port also has a pair of internal Ethernet DMA channels to + support the transmit and receive data flows. The Ethernet DMA channels + use descriptors set up in memory, the memory map of the device, and + access via the Switch Fabric. The Ethernet Controller?s DMA arbiter + handles arbitration for the Switch Fabric. The Controller also + has a register businterface for register accesses and status monitor + control. + + The PMD (Physical Media Device) interface operates in MII, GMII, or TBI + modes. The MII mode is used for connecting with 10 or 100 Mbit/s PMDs. + The GMII and TBI modes are used to connect with Gigabit PMDs. Internal + data flows to and from the Ethernet Controller through the Switch Fabric. + + Each Ethernet port uses its transmit and receive DMA channels to manage + data flows through buffer descriptors that are predefined by the + system (the descriptors can exist anywhere in the system memory map). + These descriptors are data structures that point to buffers filled + with data ready to transmit over Ethernet, or they point to empty + buffers ready to receive data from Ethernet. + + Signed-off-by: Alexandre Bounine <alexandreb@tundra.com> + Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> + +commit 78aa0c3427f3ecdeb34aabfbbe2dd23b6ad8f40e +Author: roy zang <tie-fei.zang@freescale.com> +Date: Thu Nov 2 19:01:33 2006 +0800 + + Tundra tsi108 header file. + + The Tundra Semiconductor Corporation (Tundra) Tsi108 is a host bridge for + PowerPC processors that offers numerous system interconnect options for + embedded application designers.
