[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.
