[netdrvr] pcnet32: other source formatting cleanups 

- undo some Lindent damage by indenting member names
- remove history at top of .c file, this is stored in the kernel
  repo changelog (in greater detail, even).

/*
* History:
* v0.01: Initial version
* only tested on Alpha Noname Board
* v0.02: changed IRQ handling for new interrupt scheme (dev_id)
* tested on a ASUS SP3G
* v0.10: fixed an odd problem with the 79C974 in a Compaq Deskpro XL
* looks like the 974 doesn't like stopping and restarting in a
* short period of time; now we do a reinit of the lance; the
* bug was triggered by doing ifconfig eth0 <ip> broadcast <addr>
* and hangs the machine (thanks to Klaus Liedl for debugging)
* v0.12: by suggestion from Donald Becker: Renamed driver to pcnet32,
* made it standalone (no need for lance.c)
* v0.13: added additional PCI detecting for special PCI devices (Compaq)
* v0.14: stripped down additional PCI probe (thanks to David C Niemi
* and sveneric@xs4all.nl for testing this on their Compaq boxes)
* v0.15: added 79C965 (VLB) probe
* added interrupt sharing for PCI chips
* v0.16: fixed set_multicast_list on Alpha machines
* v0.17: removed hack from dev.c; now pcnet32 uses ethif_probe in Space.c
* v0.19: changed setting of autoselect bit
* v0.20: removed additional Compaq PCI probe; there is now a working one
* in arch/i386/bios32.c
* v0.21: added endian conversion for ppc, from work by cort@cs.nmt.edu
* v0.22: added printing of status to ring dump
* v0.23: changed enet_statistics to net_devive_stats
* v0.90: added multicast filter
* added module support
* changed irq probe to new style
* added PCnetFast chip id
* added fix for receive stalls with Intel saturn chipsets
* added in-place rx skbs like in the tulip driver
* minor cleanups
* v0.91: added PCnetFast+ chip id
* back port to 2.0.x
* v1.00: added some stuff from Donald Becker's 2.0.34 version
* added support for byte counters in net_dev_stats
* v1.01: do ring dumps, only when debugging the driver
* increased the transmit timeout
* v1.02: fixed memory leak in pcnet32_init_ring()
* v1.10: workaround for stopped transmitter
* added port selection for modules
* detect special T1/E1 WAN card and setup port selection
* v1.11: fixed wrong checking of Tx errors
* v1.20: added check of return value kmalloc (cpeterso@cs.washington.edu)
* added save original kmalloc addr for freeing (mcr@solidum.com)
* added support for PCnetHome chip (joe@MIT.EDU)
* rewritten PCI card detection
* added dwio mode to get driver working on some PPC machines
* v1.21: added mii selection and mii ioctl
* v1.22: changed pci scanning code to make PPC people happy
* fixed switching to 32bit mode in pcnet32_open() (thanks
* to Michael Richard <mcr@solidum.com> for noticing this one)
* added sub vendor/device id matching (thanks again to
* Michael Richard <mcr@solidum.com>)
* added chip id for 79c973/975 (thanks to Zach Brown <zab@zabbo.net>)
* v1.23 fixed small bug, when manual selecting MII speed/duplex
* v1.24 Applied Thomas' patch to use TxStartPoint and thus decrease TxFIFO
* underflows. Added tx_start_pt module parameter. Increased
* TX_RING_SIZE from 16 to 32. Added #ifdef'd code to use DXSUFLO
* for FAST[+] chipsets. <kaf@fc.hp.com>
* v1.24ac Added SMP spinlocking - Alan Cox <alan@redhat.com>
* v1.25kf Added No Interrupt on successful Tx for some Tx's <kaf@fc.hp.com>
* v1.26 Converted to pci_alloc_consistent, Jamey Hicks / George France
* <jamey@crl.dec.com>
* - Fixed a few bugs, related to running the controller in 32bit mode.
* 23 Oct, 2000. Carsten Langgaard, carstenl@mips.com
* Copyright (C) 2000 MIPS Technologies, Inc. All rights reserved.
* v1.26p Fix oops on rmmod+insmod; plug i/o resource leak - Paul Gortmaker
* v1.27 improved CSR/PROM address detection, lots of cleanups,
* new pcnet32vlb module option, HP-PARISC support,
* added module parameter descriptions,
* initial ethtool support - Helge Deller <deller@gmx.de>
* v1.27a Sun Feb 10 2002 Go Taniguchi <go@turbolinux.co.jp>
* use alloc_etherdev and register_netdev
* fix pci probe not increment cards_found
* FD auto negotiate error workaround for xSeries250
* clean up and using new mii module
* v1.27b Sep 30 2002 Kent Yoder <yoder1@us.ibm.com>
* Added timer for cable connection state changes.
* v1.28 20 Feb 2004 Don Fry <brazilnut@us.ibm.com>
* Jon Mason <jonmason@us.ibm.com>, Chinmay Albal <albal@in.ibm.com>
* Now uses ethtool_ops, netif_msg_* and generic_mii_ioctl.
* Fixes bogus 'Bus master arbitration failure', pci_[un]map_single
* length errors, and transmit hangs. Cleans up after errors in open.
* Jim Lewis <jklewis@us.ibm.com> added ethernet loopback test.
* Thomas Munck Steenholdt <tmus@tmus.dk> non-mii ioctl corrections.
* v1.29 6 Apr 2004 Jim Lewis <jklewis@us.ibm.com> added physical
* identification code (blink led's) and register dump.
* Don Fry added timer for 971/972 so skbufs don't remain on tx ring
* forever.
* v1.30 18 May 2004 Don Fry removed timer and Last Transmit Interrupt
* (ltint) as they added complexity and didn't give good throughput.
* v1.30a 22 May 2004 Don Fry limit frames received during interrupt.
* v1.30b 24 May 2004 Don Fry fix bogus tx carrier errors with 79c973,

* v1.30f 16 Jun 2004 Don Fry cleanup IRQ to allow 0 and 1 for PCI,
* expanding on suggestions from Ralf Baechle <ralf@linux-mips.org>,
* and Brian Murphy <brian@murphy.dk>.
* v1.30g 22 Jun 2004 Patrick Simmons <psimmons@flash.net> added option
* homepna for selecting HomePNA mode for PCNet/Home 79C978.
* v1.30h 24 Jun 2004 Don Fry correctly select auto, speed, duplex in bcr32.
* v1.30i 28 Jun 2004 Don Fry change to use module_param.
* v1.30j 29 Apr 2005 Don Fry fix skb/map leak with loopback test.
* v1.31 02 Sep 2005 Hubert WS Lin <wslin@tw.ibm.c0m> added set_ringparam().
* v1.31a 12 Sep 2005 Hubert WS Lin <wslin@tw.ibm.c0m> set min ring size to 4
* to allow loopback test to work unchanged.
* v1.31b 06 Oct 2005 Don Fry changed alloc_ring to show name of device
* if allocation fails
* v1.31c 01 Nov 2005 Don Fry Allied Telesyn 2700/2701 FX are 100Mbit only.
* Force 100Mbit FD if Auto (ASEL) is selected.
* See Bugzilla 2669 and 4551.
* v1.32 18 Mar2006 Thomas Bogendoerfer and Don Fry added Multi-Phy
* handling for supporting AT-270x FTX cards with FX and Tx PHYs.
* Philippe Seewer assisted with auto negotiation and testing.
