SPDX-License-Identifier: GPL-2.0 - -============================================================================= -Linux and the 3Com EtherLink III Series Ethercards (driver v1.18c and higher) -============================================================================= - -This file contains the instructions and caveats for v1.18c and higher versions -of the 3c509 driver. You should not use the driver without reading this file. - -release 1.0 - -28 February 2002 - -Current maintainer (corrections to): - David Ruggiero - -Introduction -============ - -The following are notes and information on using the 3Com EtherLink III series -ethercards in Linux. These cards are commonly known by the most widely-used -card's 3Com model number, 3c509. They are all 10mb/s ISA-bus cards and shouldn't -be (but sometimes are) confused with the similarly-numbered PCI-bus "3c905" -(aka "Vortex" or "Boomerang") series. Kernel support for the 3c509 family is -provided by the module 3c509.c, which has code to support all of the following -models: - - - 3c509 (original ISA card) - - 3c509B (later revision of the ISA card; supports full-duplex) - - 3c589 (PCMCIA) - - 3c589B (later revision of the 3c589; supports full-duplex) - - 3c579 (EISA) - -Large portions of this documentation were heavily borrowed from the guide -written the original author of the 3c509 driver, Donald Becker. The master -copy of that document, which contains notes on older versions of the driver, -currently resides on Scyld web server: http://www.scyld.com/. - - -Special Driver Features -======================= - -Overriding card settings - -The driver allows boot- or load-time overriding of the card's detected IOADDR, -IRQ, and transceiver settings, although this capability shouldn't generally be -needed except to enable full-duplex mode (see below). An example of the syntax -for LILO parameters for doing this:: - - ether=10,0x310,3,0x3c509,eth0 - -This configures the first found 3c509 card for IRQ 10, base I/O 0x310, and -transceiver type 3 (10base2). The flag "0x3c509" must be set to avoid conflicts -with other card types when overriding the I/O address. When the driver is -loaded as a module, only the IRQ may be overridden. For example, -setting two cards to IRQ10 and IRQ11 is done by using the irq module -option:: - - options 3c509 irq=10,11 - - -Full-duplex mode -================ - -The v1.18c driver added support for the 3c509B's full-duplex capabilities. -In order to enable and successfully use full-duplex mode, three conditions -must be met: - -(a) You must have a Etherlink III card model whose hardware supports full- -duplex operations. Currently, the only members of the 3c509 family that are -positively known to support full-duplex are the 3c509B (ISA bus) and 3c589B -(PCMCIA) cards. Cards without the "B" model designation do *not* support -full-duplex mode; these include the original 3c509 (no "B"), the original -3c589, the 3c529 (MCA bus), and the 3c579 (EISA bus). - -(b) You must be using your card's 10baseT transceiver (i.e., the RJ-45 -connector), not its AUI (thick-net) or 10base2 (thin-net/coax) interfaces. -AUI and 10base2 network cabling is physically incapable of full-duplex -operation. - -(c) Most importantly, your 3c509B must be connected to a link partner that is -itself full-duplex capable. This is almost certainly one of two things: a full- -duplex-capable Ethernet switch (*not* a hub), or a full-duplex-capable NIC on -another system that's connected directly to the 3c509B via a crossover cable. - -Full-duplex mode can be enabled using 'ethtool'. - -.. warning:: - - Extremely important caution concerning full-duplex mode - - Understand that the 3c509B's hardware's full-duplex support is much more - limited than that provide by more modern network interface cards. Although - at the physical layer of the network it fully supports full-duplex operation, - the card was designed before the current Ethernet auto-negotiation (N-way) - spec was written. This means that the 3c509B family ***cannot and will not - auto-negotiate a full-duplex connection with its link partner under any - circumstances, no matter how it is initialized***. If the full-duplex mode - of the 3c509B is enabled, its link partner will very likely need to be - independently _forced_ into full-duplex mode as well; otherwise various nasty - failures will occur - at the very least, you'll see massive numbers of packet - collisions. This is one of very rare circumstances where disabling auto- - negotiation and forcing the duplex mode of a network interface card or switch - would ever be necessary or desirable. - - -Available Transceiver Types -=========================== - -For versions of the driver v1.18c and above, the available transceiver types are: - -== ========================================================================= -0 transceiver type from EEPROM config (normally 10baseT); force half-duplex -1 AUI (thick-net / DB15 connector) -2 (undefined) -3 10base2 (thin-net == coax / BNC connector) -4 10baseT (RJ-45 connector); force half-duplex mode -8 transceiver type and duplex mode taken from card's EEPROM config settings -12 10baseT (RJ-45 connector); force full-duplex mode -== ========================================================================= - -Prior to driver version 1.18c, only transceiver codes 0-4 were supported. Note -that the new transceiver codes 8 and 12 are the *only* ones that will enable -full-duplex mode, no matter what the card's detected EEPROM settings might be. -This insured that merely upgrading the driver from an earlier version would -never automatically enable full-duplex mode in an existing installation; -it must always be explicitly enabled via one of these code in order to be -activated. - -The transceiver type can be changed using 'ethtool'. - - -Interpretation of error messages and common problems ----------------------------------------------------- - -Error Messages -^^^^^^^^^^^^^^ - -eth0: Infinite loop in interrupt, status 2011. -These are "mostly harmless" message indicating that the driver had too much -work during that interrupt cycle. With a status of 0x2011 you are receiving -packets faster than they can be removed from the card. This should be rare -or impossible in normal operation. Possible causes of this error report are: - - - a "green" mode enabled that slows the processor down when there is no - keyboard activity. - - - some other device or device driver hogging the bus or disabling interrupts. - Check /proc/interrupts for excessive interrupt counts. The timer tick - interrupt should always be incrementing faster than the others. - -No received packets -^^^^^^^^^^^^^^^^^^^ - -If a 3c509, 3c562 or 3c589 can successfully transmit packets, but never -receives packets (as reported by /proc/net/dev or 'ifconfig') you likely -have an interrupt line problem. Check /proc/interrupts to verify that the -card is actually generating interrupts. If the interrupt count is not -increasing you likely have a physical conflict with two devices trying to -use the same ISA IRQ line. The common conflict is with a sound card on IRQ10 -or IRQ5, and the easiest solution is to move the 3c509 to a different -interrupt line. If the device is receiving packets but 'ping' doesn't work, -you have a routing problem. - -Tx Carrier Errors Reported in /proc/net/dev -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - - -If an EtherLink III appears to transmit packets, but the "Tx carrier errors" -field in /proc/net/dev increments as quickly as the Tx packet count, you -likely have an unterminated network or the incorrect media transceiver selected. - -3c509B card is not detected on machines with an ISA PnP BIOS. -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -While the updated driver works with most PnP BIOS programs, it does not work -with all. This can be fixed by disabling PnP support using the 3Com-supplied -setup program. - -3c509 card is not detected on overclocked machines -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -Increase the delay time in id_read_eeprom() from the current value, 500, -to an absurdly high value, such as 5000. - - -Decoding Status and Error Messages ----------------------------------- - - -The bits in the main status register are: - -===== ====================================== -value description -===== ====================================== -0x01 Interrupt latch -0x02 Tx overrun, or Rx underrun -0x04 Tx complete -0x08 Tx FIFO room available -0x10 A complete Rx packet has arrived -0x20 A Rx packet has started to arrive -0x40 The driver has requested an interrupt -0x80 Statistics counter nearly full -===== ====================================== - -The bits in the transmit (Tx) status word are: - -===== ============================================ -value description -===== ============================================ -0x02 Out-of-window collision. -0x04 Status stack overflow (normally impossible). -0x08 16 collisions. -0x10 Tx underrun (not enough PCI bus bandwidth). -0x20 Tx jabber. -0x40 Tx interrupt requested. -0x80 Status is valid (this should always be set). -===== ============================================ - - -When a transmit error occurs the driver produces a status message such as:: - - eth0: Transmit error, Tx status register 82 - -The two values typically seen here are: - -0x82 -^^^^ - -Out of window collision. This typically occurs when some other Ethernet -host is incorrectly set to full duplex on a half duplex network. - -0x88 -^^^^ - -16 collisions. This typically occurs when the network is exceptionally busy -or when another host doesn't correctly back off after a collision. If this -error is mixed with 0x82 errors it is the result of a host incorrectly set -to full duplex (see above). - -Both of these errors are the result of network problems that should be -corrected. They do not represent driver malfunction. - - -Revision history (this file) -============================ - -28Feb02 v1.0 DR New; major portions based on Becker original 3c509 docs - diff --git a/Documentation/networking/device_drivers/ethernet/index.rst b/Documentation/networking/device_drivers/ethernet/index.rst index 5f3f06111911b..e87b3bed0c1a2 100644 --- a/Documentation/networking/device_drivers/ethernet/index.rst +++ b/Documentation/networking/device_drivers/ethernet/index.rst @@ -10,7 +10,6 @@ Contents: .. toctree:: :maxdepth: 2 - 3com/3c509 3com/vortex amazon/ena altera/altera_tse diff --git a/arch/powerpc/configs/ppc6xx_defconfig b/arch/powerpc/configs/ppc6xx_defconfig index 488844fcdb62a..59163084becd9 100644 --- a/arch/powerpc/configs/ppc6xx_defconfig +++ b/arch/powerpc/configs/ppc6xx_defconfig @@ -395,7 +395,6 @@ CONFIG_NETCONSOLE=m CONFIG_TUN=m CONFIG_VETH=m CONFIG_VIRTIO_NET=m -CONFIG_EL3=m CONFIG_PCMCIA_3C574=m CONFIG_PCMCIA_3C589=m CONFIG_VORTEX=m diff --git a/drivers/net/ethernet/3com/3c509.c b/drivers/net/ethernet/3com/3c509.c deleted file mode 100644 index fb68339e1511c..0000000000000 --- a/drivers/net/ethernet/3com/3c509.c +++ /dev/null @@ -1,1448 +0,0 @@ -/* 3c509.c: A 3c509 EtherLink3 ethernet driver for linux. */ -/* - Written 1993-2000 by Donald Becker. - - Copyright 1994-2000 by Donald Becker. - Copyright 1993 United States Government as represented by the - Director, National Security Agency.
