Subject: [PATCH 1/2] net: ethernet: Remove the 8390 network drivers

commit <0cf445ceaf43> ("<netdev: Update status of 8390 based drivers>")
indicated the 8390 network drivers as orphan/obsolete in Jan 2011,
updated in the MAINTAINERS file.

now, after being exposed for 10 years to refactoring,
and no one has become its maintainer for the past 10 years,
so to remove the 8390 network drivers for good.

additionally, 8390 is a kind of old ethernet chip based on
ISA interface which is hard to find in the market.

- A PCMCIA ethernet driver for Asix AX88190-based cards
-
- The Asix AX88190 is a NS8390-derived chipset with a few nasty
- idiosyncracies that make it very inconvenient to support with a
- standard 8390 driver. This driver is based on pcnet_cs, with the
- tweaked 8390 code grafted on the end. Much of what I did was to
- clean up and update a similar driver supplied by Asix, which was
- adapted by William Lee, [email protected].

- This is the chip-specific code for many 8390-based ethernet adaptors.
- This is not a complete driver, it must be combined with board-specific
- code such as ne.c, wd.c, 3c503.c, etc.
-
- Seeing how at least eight drivers use this code, (not counting the
- PCMCIA ones either) it is easy to break some card by what seems like
- a simple innocent change. Please contact me or Donald if you think
- you have found something that needs changing. -- PG
-
- Changelog:
-
- Paul Gortmaker : remove set_bit lock, other cleanups.
- Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
- ei_block_input() for eth_io_copy_and_sum().
- Paul Gortmaker : exchange static int ei_pingpong for a #define,
- also add better Tx error handling.
- Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
- Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
- Paul Gortmaker : tweak ANK's above multicast changes a bit.
- Paul Gortmaker : update packet statistics for v2.1.x
- Alan Cox : support arbitrary stupid port mappings on the
- 68K Macintosh. Support >16bit I/O spaces
- Paul Gortmaker : add kmod support for auto-loading of the 8390
- module by all drivers that require it.
- Alan Cox : Spinlocking work, added 'BUG_83C690'
- Paul Gortmaker : Separate out Tx timeout code from Tx path.

- void block_output(struct net_device *dev, int count, const unsigned char *buf,

- Write the COUNT bytes of BUF to the packet buffer at START_PAGE. The
- "page" value uses the 8390's 256-byte pages.
- void get_8390_hdr(struct net_device *dev, struct e8390_hdr *hdr, int ring_page)
- Read the 4 byte, page aligned 8390 header. *If* there is a
- subsequent read, it will be of the rest of the packet.
- void block_input(struct net_device *dev, int count, struct sk_buff *skb, int ring_offset)
- Read COUNT bytes from the packet buffer into the skb data area. Start
- reading from RING_OFFSET, the address as the 8390 sees it. This will always

- * SMP and the 8390 setup.
- *
- * The 8390 isn't exactly designed to be multithreaded on RX/TX. There is
- * a page register that controls bank and packet buffer access. We guard
- * this with ei_local->page_lock. Nobody should assume or set the page other
- * than zero when the lock is not held. Lock holders must restore page 0
- * before unlocking. Even pure readers must take the lock to protect in
- * page 0.
- *
- * To make life difficult the chip can also be very slow. We therefore can't
- * just use spinlocks. For the longer lockups we disable the irq the device
- * sits on and hold the lock. We must hold the lock because there is a dual
- * processor case other than interrupts (get stats/set multicast list in
- * parallel with each other and transmit).
- *
- * Note: in theory we can just disable the irq on the card _but_ there is
- * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
- * enter lock, take the queued irq. So we waddle instead of flying.
- *
- * Finally by special arrangement for the purpose of being generally
- * annoying the transmit function is called bh atomic. That places
- * restrictions on the user context callers as disable_irq won't save
- * them.

- This is the chip-specific code for many 8390-based ethernet adaptors.
- This is not a complete driver, it must be combined with board-specific
- code such as ne.c, wd.c, 3c503.c, etc.
-
- Seeing how at least eight drivers use this code, (not counting the
- PCMCIA ones either) it is easy to break some card by what seems like
- a simple innocent change. Please contact me or Donald if you think
- you have found something that needs changing. -- PG
-
-
- Changelog:
-
- Paul Gortmaker : remove set_bit lock, other cleanups.
- Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
- ei_block_input() for eth_io_copy_and_sum().
- Paul Gortmaker : exchange static int ei_pingpong for a #define,
- also add better Tx error handling.
- Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
- Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
- Paul Gortmaker : tweak ANK's above multicast changes a bit.
- Paul Gortmaker : update packet statistics for v2.1.x
- Alan Cox : support arbitrary stupid port mappings on the
- 68K Macintosh. Support >16bit I/O spaces
- Paul Gortmaker : add kmod support for auto-loading of the 8390
- module by all drivers that require it.
- Alan Cox : Spinlocking work, added 'BUG_83C690'
- Paul Gortmaker : Separate out Tx timeout code from Tx path.
- Paul Gortmaker : Remove old unused single Tx buffer code.
- Hayato Fujiwara : Add m32r support.
- Paul Gortmaker : use skb_padto() instead of stack scratch area

-/*
- * SMP and the 8390 setup.
- *
- * The 8390 isn't exactly designed to be multithreaded on RX/TX. There is
- * a page register that controls bank and packet buffer access. We guard
- * this with ei_local->page_lock. Nobody should assume or set the page other
- * than zero when the lock is not held. Lock holders must restore page 0
- * before unlocking. Even pure readers must take the lock to protect in
- * page 0.
- *
- * To make life difficult the chip can also be very slow. We therefore can't
- * just use spinlocks. For the longer lockups we disable the irq the device
- * sits on and hold the lock. We must hold the lock because there is a dual
- * processor case other than interrupts (get stats/set multicast list in
- * parallel with each other and transmit).
- *
- * Note: in theory we can just disable the irq on the card _but_ there is
- * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
- * enter lock, take the queued irq. So we waddle instead of flying.
- *
- * Finally by special arrangement for the purpose of being generally
- * annoying the transmit function is called bh atomic. That places
- * restrictions on the user context callers as disable_irq won't save
- * them.
- *
- * Additional explanation of problems with locking by Alan Cox:
- *
- * "The author (me) didn't use spin_lock_irqsave because the slowness of the
- * card means that approach caused horrible problems like losing serial data
- * at 38400 baud on some chips. Remember many 8390 nics on PCI were ISA
- * chips with FPGA front ends.
- *
- * Ok the logic behind the 8390 is very simple:
- *
- * Things to know
- * - IRQ delivery is asynchronous to the PCI bus
- * - Blocking the local CPU IRQ via spin locks was too slow
- * - The chip has register windows needing locking work
- *
- * So the path was once (I say once as people appear to have changed it
- * in the mean time and it now looks rather bogus if the changes to use
- * disable_irq_nosync_irqsave are disabling the local IRQ)
- *
- *
- * Take the page lock
- * Mask the IRQ on chip
- * Disable the IRQ (but not mask locally- someone seems to have
- * broken this with the lock validator stuff)
- * [This must be _nosync as the page lock may otherwise
- * deadlock us]
- * Drop the page lock and turn IRQs back on
- *
- * At this point an existing IRQ may still be running but we can't
- * get a new one
- *
- * Take the lock (so we know the IRQ has terminated) but don't mask
- * the IRQs on the processor
- * Set irqlock [for debug]
- *
- * Transmit (slow as ****)
- *
- * re-enable the IRQ
- *
- *
- * We have to use disable_irq because otherwise you will get delayed
- * interrupts on the APIC bus deadlocking the transmit path.
- *
- * Quite hairy but the chip simply wasn't designed for SMP and you can't
- * even ACK an interrupt without risking corrupting other parallel
- * activities on the chip." [lkml, 25 Jul 2007]

-
- This driver should work with many programmed-I/O 8390-based ethernet
- boards. Currently it supports the NE1000, NE2000, many clones,
- and some Cabletron products.
-
- Changelog:
-
- Paul Gortmaker : use ENISR_RDC to monitor Tx PIO uploads, made
- sanity checks and bad clone support optional.
- Paul Gortmaker : new reset code, reset card after probe at boot.
- Paul Gortmaker : multiple card support for module users.
- Paul Gortmaker : Support for PCI ne2k clones, similar to lance.c
- Paul Gortmaker : Allow users with bad cards to avoid full probe.
- Paul Gortmaker : PCI probe changes, more PCI cards supported.
- [email protected] : Changed init order so an interrupt will only
- occur after memory is allocated for dev->priv. Deallocated memory
- last in cleanup_modue()
- Richard Guenther : Added support for ISAPnP cards
- Paul Gortmaker : Discontinued PCI support - use ne2k-pci.c instead.
- Hayato Fujiwara : Add m32r support.

- A PCMCIA ethernet driver for NS8390-based cards
-
- This driver supports the D-Link DE-650 and Linksys EthernetCard
- cards, the newer D-Link and Linksys combo cards, Accton EN2212
- cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
- mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
- Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
- mode. It will also handle the Socket EA card in either mode.

-/* smc-ultra.c: A SMC Ultra ethernet driver for linux. */
-/*
- This is a driver for the SMC Ultra and SMC EtherEZ ISA ethercards.
-
- Written 1993-1998 by Donald Becker.
-
- Copyright 1993 United States Government as represented by the
- Director, National Security Agency.

-
- This driver uses the cards in the 8390-compatible mode.
- Most of the run-time complexity is handled by the generic code in
- 8390.c. The code in this file is responsible for
-
- ultra_probe() Detecting and initializing the card.
- ultra_probe1()
- ultra_probe_isapnp()
-
- ultra_open() The card-specific details of starting, stopping
- ultra_reset_8390() and resetting the 8390 NIC core.
- ultra_close()
-
- ultra_block_input() Routines for reading and writing blocks of
- ultra_block_output() packet buffer memory.
- ultra_pio_input()
- ultra_pio_output()
-
- This driver enables the shared memory only when doing the actual data
- transfers to avoid a bug in early version of the card that corrupted
- data transferred by a AHA1542.
-
- This driver now supports the programmed-I/O (PIO) data transfer mode of
- the EtherEZ. It does not use the non-8390-compatible "Altego" mode.
- That support (if available) is in smc-ez.c.
-
- Changelog:
-
- Paul Gortmaker : multiple card support for module users.
- Donald Becker : 4/17/96 PIO support, minor potential problems avoided.
- Donald Becker : 6/6/96 correctly set auto-wrap bit.
- Alexander Sotirov : 1/20/01 Added support for ISAPnP cards
-
- Note about the ISA PnP support:
-
- This driver can not autoprobe for more than one SMC EtherEZ PnP card.
- You have to configure the second card manually through the /proc/isapnp
- interface and then load the module with an explicit io=0x___ option.
