Hello list,

inside the automatic U-Boot patch tracking system a new ticket
[DNX#2006110242000092] was created:

<snip>
> Tundra tsi108 on chip Ethernet controller support.
> The following is a brief description of the Ethernet controller:
> 
> The Tsi108/9 Ethernet Controller connects Switch Fabric to two
> independent Gigabit Ethernet ports,E0 and E1.  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 bus interface 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.
