Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

Linux Kernel Additions:
0.99H+lk0.9 - David S. Miller - softnet, PCI DMA updates
0.99H+lk1.0 - Jeff Garzik <jgarzik@pobox.com>
Remove compatibility defines for kernel versions < 2.2.x.
Update for new 2.3.x module interface
LK1.1.2 (March 19, 2000)
* New PCI interface (jgarzik)
LK1.1.3 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
- Merged with 3c575_cb.c
- Don't set RxComplete in boomerang interrupt enable reg
- spinlock in vortex_timer to protect mdio functions
- disable local interrupts around call to vortex_interrupt in
vortex_tx_timeout() (So vortex_interrupt can use spin_lock())
- Select window 3 in vortex_timer()'s write to Wn3_MAC_Ctrl
- In vortex_start_xmit(), move the lock to _after_ we've altered
vp->cur_tx and vp->tx_full. This defeats the race between
vortex_start_xmit() and vortex_interrupt which was identified
by Bogdan Costescu.
- Merged back support for six new cards from various sources
- Set vortex_have_pci if pci_module_init returns zero (fixes cardbus
insertion oops)
- Tell it that 3c905C has NWAY for 100bT autoneg
- Fix handling of SetStatusEnd in 'Too much work..' code, as
per 2.3.99's 3c575_cb (Dave Hinds).
- Split ISR into two for vortex & boomerang
- Fix MOD_INC/DEC races
- Handle resource allocation failures.
- Fix 3CCFE575CT LED polarity
- Make tx_interrupt_mitigation the default
LK1.1.4 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
- Add extra TxReset to vortex_up() to fix 575_cb hotplug initialisation probs.
- Put vortex_info_tbl into __devinitdata
- In the vortex_error StatsFull HACK, disable stats in vp->intr_enable as well
as in the hardware.
- Increased the loop counter in issue_and_wait from 2,000 to 4,000.
LK1.1.5 28 April 2000, andrewm
- Added powerpc defines (John Daniel <jdaniel@etresoft.com> said these work...)
- Some extra diagnostics
- In vortex_error(), reset the Tx on maxCollisions. Otherwise most
chips usually get a Tx timeout.
- Added extra_reset module parm
- Replaced some inline timer manip with mod_timer
(Franois romieu <Francois.Romieu@nic.fr>)
- In vortex_up(), don't make Wn3_config initialisation dependent upon has_nway
(this came across from 3c575_cb).
LK1.1.6 06 Jun 2000, andrewm
- Backed out the PPC defines.
- Use del_timer_sync(), mod_timer().
- Fix wrapped ulong comparison in boomerang_rx()
- Add IS_TORNADO, use it to suppress 3c905C checksum error msg
(Donald Becker, I Lee Hetherington <ilh@sls.lcs.mit.edu>)
- Replace union wn3_config with BFINS/BFEXT manipulation for
sparc64 (Pete Zaitcev, Peter Jones)
- In vortex_error, do_tx_reset and vortex_tx_timeout(Vortex):
do a netif_wake_queue() to better recover from errors. (Anders Pedersen,
Donald Becker)
- Print a warning on out-of-memory (rate limited to 1 per 10 secs)
- Added two more Cardbus 575 NICs: 5b57 and 6564 (Paul Wagland)
LK1.1.7 2 Jul 2000 andrewm
- Better handling of shared IRQs
- Reset the transmitter on a Tx reclaim error
- Fixed crash under OOM during vortex_open() (Mark Hemment)
- Fix Rx cessation problem during OOM (help from Mark Hemment)
- The spinlocks around the mdio access were blocking interrupts for 300uS.
Fix all this to use spin_lock_bh() within mdio_read/write
- Only write to TxFreeThreshold if it's a boomerang - other NICs don't
have one.
- Added 802.3x MAC-layer flow control support
LK1.1.8 13 Aug 2000 andrewm
- Ignore request_region() return value - already reserved if Cardbus.
- Merged some additional Cardbus flags from Don's 0.99Qk
- Some fixes for 3c556 (Fred Maciel)
- Fix for EISA initialisation (Jan Rekorajski)
- Renamed MII_XCVR_PWR and EEPROM_230 to align with 3c575_cb and D. Becker's drivers
- Fixed MII_XCVR_PWR for 3CCFE575CT
- Added INVERT_LED_PWR, used it.
- Backed out the extra_reset stuff
LK1.1.9 12 Sep 2000 andrewm
- Backed out the tx_reset_resume flags. It was a no-op.
- In vortex_error, don't reset the Tx on txReclaim errors
- In vortex_error, don't reset the Tx on maxCollisions errors.
Hence backed out all the DownListPtr logic here.
- In vortex_error, give Tornado cards a partial TxReset on
maxCollisions (David Hinds). Defined MAX_COLLISION_RESET for this.
- Redid some driver flags and device names based on pcmcia_cs-3.1.20.
- Fixed a bug where, if vp->tx_full is set when the interface
is downed, it remains set when the interface is upped. Bad
things happen.
LK1.1.10 17 Sep 2000 andrewm
- Added EEPROM_8BIT for 3c555 (Fred Maciel)
- Added experimental support for the 3c556B Laptop Hurricane (Louis Gerbarg)
- Add HAS_NWAY to "3c900 Cyclone 10Mbps TPO"
LK1.1.11 13 Nov 2000 andrewm
- Dump MOD_INC/DEC_USE_COUNT, use SET_MODULE_OWNER
LK1.1.12 1 Jan 2001 andrewm (2.4.0-pre1)
- Call pci_enable_device before we request our IRQ (Tobias Ringstrom)
- Add 3c590 PCI latency timer hack to vortex_probe1 (from 0.99Ra)
- Added extended issue_and_wait for the 3c905CX.
- Look for an MII on PHY index 24 first (3c905CX oddity).
- Add HAS_NWAY to 3cSOHO100-TX (Brett Frankenberger)
- Don't free skbs we don't own on oom path in vortex_open().
LK1.1.13 27 Jan 2001
- Added explicit `medialock' flag so we can truly
lock the media type down with `options'.
- "check ioremap return and some tidbits" (Arnaldo Carvalho de Melo <acme@conectiva.com.br>)
- Added and used EEPROM_NORESET for 3c556B PM resumes.
- Fixed leakage of vp->rx_ring.
- Break out separate HAS_HWCKSM device capability flag.
- Kill vp->tx_full (ANK)
- Merge zerocopy fragment handling (ANK?)
LK1.1.14 15 Feb 2001
- Enable WOL. Can be turned on with `enable_wol' module option.
- EISA and PCI initialisation fixes (jgarzik, Manfred Spraul)
- If a device's internalconfig register reports it has NWAY,
use it, even if autoselect is enabled.
LK1.1.15 6 June 2001 akpm
- Prevent double counting of received bytes (Lars Christensen)
- Add ethtool support (jgarzik)
- Add module parm descriptions (Andrzej M. Krzysztofowicz)
- Implemented alloc_etherdev() API
- Special-case the 'Tx error 82' message.
LK1.1.16 18 July 2001 akpm
- Make NETIF_F_SG dependent upon nr_free_highpages(), not on CONFIG_HIGHMEM
- Lessen verbosity of bootup messages
- Fix WOL - use new PM API functions.
- Use netif_running() instead of vp->open in suspend/resume.
- Don't reset the interface logic on open/close/rmmod. It upsets
autonegotiation, and hence DHCP (from 0.99T).
- Back out EEPROM_NORESET flag because of the above (we do it for all
NICs).
- Correct 3c982 identification string
- Rename wait_for_completion() to issue_and_wait() to avoid completion.h
clash.
LK1.1.17 18Dec01 akpm
- PCI ID 9805 is a Python-T, not a dual-port Cyclone. Apparently.
And it has NWAY.
- Mask our advertised modes (vp->advertising) with our capabilities
(MII reg5) when deciding which duplex mode to use.
- Add `global_options' as default for options[]. Ditto global_enable_wol,
global_full_duplex.
LK1.1.18 01Jul02 akpm
- Fix for undocumented transceiver power-up bit on some 3c566B's
(Donald Becker, Rahul Karnik)
- See http://www.zip.com.au/~akpm/linux/#3c59x-2.3 for more details.
- Also see Documentation/networking/vortex.txt
LK1.1.19 10Nov02 Marc Zyngier <maz@wild-wind.fr.eu.org>
- EISA sysfs integration.

Theory of Operation
I. Board Compatibility
This device driver is designed for the 3Com FastEtherLink and FastEtherLink
XL, 3Com's PCI to 10/100baseT adapters. It also works with the 10Mbs
versions of the FastEtherLink cards. The supported product IDs are
3c590, 3c592, 3c595, 3c597, 3c900, 3c905
The related ISA 3c515 is supported with a separate driver, 3c515.c, included
with the kernel source or available from
cesdis.gsfc.nasa.gov:/pub/linux/drivers/3c515.html
II. Board-specific settings
PCI bus devices are configured by the system at boot time, so no jumpers
need to be set on the board. The system BIOS should be set to assign the
PCI INTA signal to an otherwise unused system IRQ line.
The EEPROM settings for media type and forced-full-duplex are observed.
The EEPROM media type should be left at the default "autoselect" unless using
10base2 or AUI connections which cannot be reliably detected.
III. Driver operation
The 3c59x series use an interface that's very similar to the previous 3c5x9
series. The primary interface is two programmed-I/O FIFOs, with an
alternate single-contiguous-region bus-master transfer (see next).
The 3c900 "Boomerang" series uses a full-bus-master interface with separate
lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
DEC Tulip and Intel Speedo3. The first chip version retains a compatible
programmed-I/O interface that has been removed in 'B' and subsequent board
revisions.
One extension that is advertised in a very large font is that the adapters
are capable of being bus masters. On the Vortex chip this capability was
only for a single contiguous region making it far less useful than the full
bus master capability. There is a significant performance impact of taking
an extra interrupt or polling for the completion of each transfer, as well
as difficulty sharing the single transfer engine between the transmit and
receive threads. Using DMA transfers is a win only with large blocks or
with the flawed versions of the Intel Orion motherboard PCI controller.
The Boomerang chip's full-bus-master interface is useful, and has the
currently-unused advantages over other similar chips that queued transmit
packets may be reordered and receive buffer groups are associated with a
single frame.
With full-bus-master support, this driver uses a "RX_COPYBREAK" scheme.
Rather than a fixed intermediate receive buffer, this scheme allocates
full-sized skbuffs as receive buffers. The value RX_COPYBREAK is used as
the copying breakpoint: it is chosen to trade-off the memory wasted by
passing the full-sized skbuff to the queue layer for all frames vs. the
copying cost of copying a frame to a correctly-sized skbuff.
IIIC. Synchronization
The driver runs as two independent, single-threaded flows of control. One
is the send-packet routine, which enforces single-threaded use by the
dev->tbusy flag. The other thread is the interrupt handler, which is single
threaded by the hardware and other software.
IV. Notes
Thanks to Cameron Spitzer and Terry Murphy of 3Com for providing development
3c590, 3c595, and 3c900 boards.
The name "Vortex" is the internal 3Com project name for the PCI ASIC, and
the EISA version is called "Demon". According to Terry these names come
from rides at the local amusement park.
The new chips support both ethernet (1.5K) and FDDI (4.5K) packet sizes!
This driver only supports ethernet packets because of the skbuff allocation
limit of 4K.

[NET]: Remove gratuitous use of skb->tail in network drivers. Many drivers use skb->tail unnecessarily. In these situations, the code roughly looks like: dev = dev_alloc_skb(...); [optional] skb_reserve(skb, ...); ... skb->tail ... But even if the skb_reserve() happens, skb->data equals skb->tail. So it doesn't make any sense to use anything other than skb->data in these cases. Another case was the s2io.c driver directly mucking with the skb->data and skb->tail pointers. It really just wanted to do an skb_reserve(), so that's what the code was changed to do instead. Another reason I'm making this change as it allows some SKB cleanups I have planned simpler to merge. In those cleanups, skb->head, skb->tail, and skb->end pointers are removed, and replaced with skb->head_room and skb->tail_room integers. Signed-off-by: David S.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
