+    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, william@asix.com.tw.

+  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.

+ *	this with ei_local->page_lock. Nobody should assume or set the page other

+ *	before unlocking. Even pure readers must take the lock to protect in

+ *
+ *	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

+
+
+  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.
+    rjohnson@analogic.com : 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.

+    CCAE support.  Drivers merged back together, and shared-memory
+    Socket EA support added, by Ken Raeburn, September 1995.

+/* 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.
+
+	The author may be reached as becker@scyld.com, or C/O
+	Scyld Computing Corporation
+	410 Severn Ave., Suite 210
+	Annapolis MD 21403
+
+	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.
