Since Intel agreed to submit further updates via broken-up patches
like they do currently (and admirably) for e1000 and e100, I agreed
to merge this update to bring the driver up to speed.

Contributed by: Ayyappan.Veeraiyan@intel.com

Changes:

Features implemented

*	Support for new 850nm adapters.
*	Copyright notice updated to include year 2004.
*	Fix for "ixgb does not maintain non-default MTU setting across a
link loss" issue - When link loss happens in non-default MTU
environment, driver will incorrectly operate with default 1500 MTU
setting.
*	Netpoll support added
*	Ethtool support - status functionality, FlowControl interface,
Checksum interface, TSO and Scatter Gather interfaces
*	Race condition fix - Race condition (TX path) exists between
ixgb_xmit_frame and clean_tx_irq routines in handling the queue.
* 	Removed dead code segments (#if 0)


Performance improvement features 
*	Mod operator usage is removed - used to cause performance
problems in non-IA architecture based machines
*	Multiple ICR register read in ISR is avoided
*	RS bit set on only 'end of packet' TX descriptors - to avoid
multiple writebacks by controller for packets with multiple descriptors.
*	RX descriptors prefetch is done - improved 1500 MTU TX
performance


All relevant e1000 driver cleanups ported to ixgb
*	Valid error propagation in functions ixgb_up, ixgb_probe,
ixgb_open. 
* 	NAPI code cleanups
* 	u8, u16 and u32 data types are changed to uint8_t, uint16_t and
uint32_t respectively. We use these types on our shared code for
multiple OSes and also to make it uniform with e1000 driver.
*	Some functions in ixgb_main.c are moved to different location -
This enables easy porting of e1000 bug fixes to ixgb

The following patch to net/sk98lin/skvpd.c was put together by Marc Bouget,
mbouget at club-internet.fr.

This patch works around a corrupt EEPROM (VPD?) in the ASUS K8V Deluxe SE
motherboard ethernet chipset and allows the network driver to work
correctly.  We have written to ASUS and the sk98lin maintainers but have
not heard anything back.

Found another patch that should go with this batch:

Switch to netdev_priv(). Fix outdated comment and bump version number
while we're at it.

Replace USE_MEM and USE_IO with USE_MMIO define.

- Switch to 8 char tabs.
- Remove kernel log pointer to the scyld web site -- it's
  a) fairly irrelevant by now and
  b) gone.
- Remove Emacs Voodoo.
- More white space clean up, mostly coding style.

This patch renames symbols:
via_rhine_* -> rhine_*
struct netdev_private *np -> struct rhine_private *rp

Lucas Nussbaum and Dirk Koeppen each found independently that the code
for forcing media options in via-rhine is borked and suggested the fix
below. I've been sitting on this way too long because there is more
badness in the immediate vicinity which needs a bigger surgery.

The second hunk fixes a braino I managed to introduce myself.

Joe Perches pointed out an error in patch 8.  As I looked at the results
closer 3 out of 4 looked correct.  This fixes the output for the last
case.  Output is now the same on IA32 and PPC64 hardware.

the Broadcom BCM4401 driver restores pci configuration on resume only when the 
device is up. On my notebook, this leads to a failure when the device is down 
during the S3 cycle. Short solution for now: Always restore pci config.

Also included are driver version update and change logs

Reduce scope of tx_lock

1) Provides support for new FarSync cards T1U, T2U, T4U and TE1
2) Provides support for an E1 interface
3) Provides support for a variant of X.21 that allows transmit and
receive clocks
4) Provide a raw socket interface directly to the data from the line.
5) Improves performance with less time in interrupts and more in BH's

This patch avoids a timeout when entering/exiting promiscuous mode with
tcpdump.  All pending xmit operations are flushed and if the queue is
full the timeout will occur.  The wake_queue avoids that timeout.
Tested ppc64 and ia32.

This patch corrects a printk when executed on a big-endian system.  Tested
ppc64.

The 79C973 version of the pcnet32 chipset would report all transmit
operations as being sent with a carrier error.  The root cause was
writing reserved bits in bcr33.  It caused the 973 to report xmit
as errors, and caused 975 and 976 to hard hang when reading bcr34.

My thanks to Bruce Penrod for his help in finding the cause of this
bug.

The current code will allow an infinite number of frames to be received
during one interrupt.  Tested ia32 and ppc64.

This removes the timer I recently added, and the 'ltint' interrupt
mitigation from the 79C971 and 79C972. It did not improve performance,
added complexity, and was a bad idea in hind sight.

This patch fixes a boundary condition.  It is possible to get an
interrupt and have the transmit queue completely full.  Without this
the driver will leak skb's and pci maps (if the arch supports them).

This patch correctly identifies the 79C976 as a PCnet/PRO not a FAST III.

This patch fixes a hard hang with 79C975 and 79C976 chip variants when
dumping BCR register #34.

This patch adds 'static' to two routines.  The prototype has static but
the instantiation did not.
