/* 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. This software may be used and distributed according to the terms of the GNU General Public License, incorporated herein by reference. This driver is for the 3Com EtherLinkIII series. The author may be reached as becker@scyld.com, or C/O Scyld Computing Corporation 410 Severn Ave., Suite 210 Annapolis MD 21403 Known limitations: Because of the way 3c509 ISA detection works it's difficult to predict a priori which of several ISA-mode cards will be detected first. This driver does not use predictive interrupt mode, resulting in higher packet latency but lower overhead. If interrupts are disabled for an unusually long time it could also result in missed packets, but in practice this rarely happens. FIXES: Alan Cox: Removed the 'Unexpected interrupt' bug. Michael Meskes: Upgraded to Donald Becker's version 1.07. Alan Cox: Increased the eeprom delay. Regardless of what the docs say some people definitely get problems with lower (but in card spec) delays v1.10 4/21/97 Fixed module code so that multiple cards may be detected, other cleanups. -djb Andrea Arcangeli: Upgraded to Donald Becker's version 1.12. Rick Payne: Fixed SMP race condition v1.13 9/8/97 Made 'max_interrupt_work' an insmod-settable variable -djb v1.14 10/15/97 Avoided waiting..discard message for fast machines -djb v1.15 1/31/98 Faster recovery for Tx errors. -djb v1.16 2/3/98 Different ID port handling to avoid sound cards. -djb v1.18 12Mar2001 Andrew Morton - Avoid bogus detect of 3c590's (Andrzej Krzysztofowicz) - Reviewed against 1.18 from scyld.com v1.18a 17Nov2001 Jeff Garzik <jgarzik@pobox.com> - ethtool support v1.18b 1Mar2002 Zwane Mwaikambo <zwane@commfireservices.com> - Power Management support v1.18c 1Mar2002 David Ruggiero <jdr@farfalle.com> - Full duplex support v1.19 16Oct2002 Zwane Mwaikambo <zwane@linuxpower.ca> - Additional ethtool features v1.19a 28Oct2002 Davud Ruggiero <jdr@farfalle.com> - Increase *read_eeprom udelay to workaround oops with 2 cards. v1.19b 08Nov2002 Marc Zyngier <maz@wild-wind.fr.eu.org> - Introduce driver model for EISA cards. v1.20 04Feb2008 Ondrej Zary <linux@rainbow-software.org> - convert to isa_driver and pnp_driver and some cleanups */ #define DRV_NAME "3c509" /* A few values that may be tweaked. */ /* Time in jiffies before concluding the transmitter is hung. */ #define TX_TIMEOUT (400*HZ/1000) #include <linux/module.h> #include <linux/isa.h> #include <linux/pnp.h> #include <linux/string.h> #include <linux/interrupt.h> #include <linux/errno.h> #include <linux/in.h> #include <linux/ioport.h> #include <linux/init.h> #include <linux/netdevice.h> #include <linux/etherdevice.h> #include <linux/pm.h> #include <linux/skbuff.h> #include <linux/delay.h> /* for udelay() */ #include <linux/spinlock.h> #include <linux/ethtool.h> #include <linux/device.h> #include <linux/eisa.h> #include <linux/bitops.h> #include <linux/vermagic.h> #include <linux/uaccess.h> #include <asm/io.h> #include <asm/irq.h> #ifdef EL3_DEBUG static int el3_debug = EL3_DEBUG; #else static int el3_debug = 2; #endif /* Used to do a global count of all the cards in the system.
