The Tulip Ethernet Card Driver

is maintained by Jeff Garzik (<email>jgarzik@pobox.com</email>).

</para>

<para>

The Tulip driver was developed by Donald Becker and changed by

Jeff Garzik, Takashi Manabe and a cast of thousands.

</para>

<para>

For 2.4.x and later kernels, the Linux Tulip driver is available at

<ulink url="http://sourceforge.net/projects/tulip/">http://sourceforge.net/projects/tulip/</ulink>

</para>

<para>

	This driver is for the Digital "Tulip" Ethernet adapter interface.

	It should work with most DEC 21*4*-based chips/ethercards, as well as

	with work-alike chips from Lite-On (PNIC) and Macronix (MXIC) and ASIX.

    <title>Driver Compatibility</title>

<para>

This device driver is designed for the DECchip "Tulip", Digital's

single-chip ethernet controllers for PCI (now owned by Intel).

Supported members of the family

are the 21040, 21041, 21140, 21140A, 21142, and 21143.  Similar work-alike

chips from Lite-On, Macronics, ASIX, Compex and other listed below are also

supported.

</para>

<para>

These chips are used on at least 140 unique PCI board designs.  The great

number of chips and board designs supported is the reason for the

driver size and complexity.  Almost of the increasing complexity is in the

board configuration and media selection code.  There is very little

increasing in the operational critical path length.

</para>

  </chapter>

  <chapter id="board-settings">

    <title>Board-specific Settings</title>

<para>

PCI bus devices are configured by the system at boot time, so no jumpers

need to be set on the board.  The system BIOS preferably should assign the

PCI INTA signal to an otherwise unused system IRQ line.

</para>

<para>

Some boards have EEPROMs tables with default media entry.  The factory default

is usually "autoselect".  This should only be overridden when using

transceiver connections without link beat e.g. 10base2 or AUI, or (rarely!)

for forcing full-duplex when used with old link partners that do not do

autonegotiation.

</para>

  </chapter>

  <chapter id="driver-operation">

    <title>Driver Operation</title>

<sect1><title>Ring buffers</title>

<para>

The Tulip can use either ring buffers or lists of Tx and Rx descriptors.

This driver uses statically allocated rings of Rx and Tx descriptors, set at

compile time by RX/TX_RING_SIZE.  This version of the driver allocates skbuffs

for the Rx ring buffers at open() time and passes the skb->data field to the

Tulip as receive data buffers.  When an incoming frame is less than

RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is

copied to the new skbuff.  When the incoming frame is larger, the skbuff is

passed directly up the protocol stack and replaced by a newly allocated

skbuff.

</para>

<para>

The RX_COPYBREAK value is chosen to trade-off the memory wasted by

using a full-sized skbuff for small frames vs. the copying costs of larger

frames.  For small frames the copying cost is negligible (esp. considering

that we are pre-loading the cache with immediately useful header

information).  For large frames the copying cost is non-trivial, and the

larger copy might flush the cache of useful data.  A subtle aspect of this

choice is that the Tulip only receives into longword aligned buffers, thus

the IP header at offset 14 isn't longword aligned for further processing.

Copied frames are put into the new skbuff at an offset of "+2", thus copying

has the beneficial effect of aligning the IP header and preloading the

cache.

</para>

</sect1>

<sect1><title>Synchronization</title>

<para>

The driver runs as two independent, single-threaded flows of control.  One

is the send-packet routine, which enforces single-threaded use by the

dev->tbusy flag.  The other thread is the interrupt handler, which is single

threaded by the hardware and other software.

</para>

<para>

The send packet thread has partial control over the Tx ring and 'dev->tbusy'

flag.  It sets the tbusy flag whenever it's queuing a Tx packet. If the next

queue slot is empty, it clears the tbusy flag when finished otherwise it sets

the 'tp->tx_full' flag.

</para>

<para>

The interrupt handler has exclusive control over the Rx ring and records stats

from the Tx ring.  (The Tx-done interrupt can't be selectively turned off, so

we can't avoid the interrupt overhead by having the Tx routine reap the Tx

stats.)	 After reaping the stats, it marks the queue entry as empty by setting

the 'base' to zero.	 Iff the 'tp->tx_full' flag is set, it clears both the

tx_full and tbusy flags.

</para>

    <title>Errata</title>

<para>

The old DEC databooks were light on details.

The 21040 databook claims that CSR13, CSR14, and CSR15 should each be the last

register of the set CSR12-15 written.  Hmmm, now how is that possible?

</para>

<para>

The DEC SROM format is very badly designed not precisely defined, leading to

part of the media selection junkheap below.  Some boards do not have EEPROM

media tables and need to be patched up.  Worse, other boards use the DEC

design kit media table when it isn't correct for their board.

</para>

<para>

We cannot use MII interrupts because there is no defined GPIO pin to attach

them.  The MII transceiver status is polled using an kernel timer.
