Subject: [TG3]: Enable TSO by default

Enable TSO by default on newer chips that support TSO in hardware.
Leave TSO off by default on older chips that do firmware TSO because
performance is slightly lower.

Subject: [TG3]: Support shutdown WoL.

Support WoL during shutdown by calling
tg3_set_power_state(tp, PCI_D3hot) during tg3_close().

Change the power state parameter to pci_power_t type and use
constants defined in pci.h.

Certain ethtool operations cannot be performed after tg3_close()
because the device will go to low power state. Add return -EAGAIN
in such cases where appropriate.

Subject: [BNX2]: Fix bug when rx ring is full

Fix the rx code path that does not handle the full rx ring correctly.

When the rx ring is set to the max. size (i.e. 255), the consumer and
producer indices will be the same when completing an rx packet. Fix
the rx code to handle this condition properly.

Subject: [BNX2]: Support larger rx ring sizes (part 1)

Increase maximum receive ring size from 255 to 1020 by supporting
up to 4 linked pages of receive descriptors. To accomodate the
higher memory usage, each physical descriptor page is allocated
separately and the software ring that keeps track of the SKBs and the
DMA addresses is allocated using vmalloc.

Some of the receive-related fields in the bp structure are re-
organized a bit for better locality of reference.

The max. was reduced to 1020 from 4080 after discussion with David
Miller.

This patch contains ring init code changes only. This next patch
contains rx data path code changes.

Subject: [IRDA]: nsc-ircc: ISAPnP support

This enables PnP support for the nsc-ircc chipset.
Since we can't fetch the chipset cfg_base from the PnP layer, we just use
the PnP information as one more hint when probing the chip.

Here goes a patch for supporting TOIM3232 based serial IrDA dongles.
The code is based on the tekram dongle code.

It's been tested with a TOIM3232 based IRWave 320S dongle. It may work
for TOIM4232 dongles, although it's not been tested.

+ * PROTOCOL:
+ *
+ * The protocol for talking to the TOIM3232 is quite easy, and is
+ * designed to interface with RS232 with only level convertors. The
+ * BR/~D line on the chip is brought high to signal 'command mode',
+ * where a command byte is sent to select the baudrate of the RS232
+ * interface and the pulse length of the IRDA output. When BR/~D
+ * is brought low, the dongle then changes to the selected baudrate,
+ * and the RS232 interface is used for data until BR/~D is brought
+ * high again. The initial speed for the TOIMx323 after RESET is
+ * 9600 baud.  The baudrate for command-mode is the last selected
+ * baud-rate, or 9600 after a RESET.
+ *
+ * The  dongle I have (below) adds some extra hardware on the front end,
+ * but this is mostly directed towards pariasitic power from the RS232
+ * line rather than changing very much about how to communicate with
+ * the TOIM3232.
+ *
+ * The protocol to talk to the TOIM4232 chipset seems to be almost
+ * identical to the TOIM3232 (and the 4232 datasheet is more detailed)
+ * so this code will probably work on that as well, although I haven't
+ * tested it on that hardware.
+ *
+ * Target dongle variations that might be common:
+ *
+ * DTR and RTS function:
+ *   The data sheet for the 4232 has a sample implementation that hooks the
+ *   DTR and RTS lines to the RESET and BaudRate/~Data lines of the
+ *   chip (through line-converters). Given both DTR and RTS would have to
+ *   be held low in normal operation, and the TOIMx232 requires +5V to
+ *   signal ground, most dongle designers would almost certainly choose
+ *   an implementation that kept at least one of DTR or RTS high in
+ *   normal operation to provide power to the dongle, but will likely
+ *   vary between designs.
+ *
+ * User specified command bits:
+ *  There are two user-controllable output lines from the TOIMx232 that
+ *  can be set low or high by setting the appropriate bits in the
+ *  high-nibble of the command byte (when setting speed and pulse length).
+ *  These might be used to switch on and off added hardware or extra
+ *  dongle features.
+ *
+ *
+ * Target hardware: IRWave IR320ST-2
+ *
+ * 	The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic
+ * 	TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transciever.
+ * 	It uses a hex inverter and some discrete components to buffer and
+ * 	line convert the RS232 down to 5V.
+ *
+ * 	The dongle is powered through a voltage regulator, fed by a large
+ * 	capacitor. To switch the dongle on, DTR is brought high to charge
+ * 	the capacitor and drive the voltage regulator. DTR isn't associated
+ * 	with any control lines on the TOIM3232. Parisitic power is also taken
+ * 	from the RTS, TD and RD lines when brought high, but through resistors.
+ * 	When DTR is low, the circuit might lose power even with RTS high.
+ *
+ * 	RTS is inverted and attached to the BR/~D input pin. When RTS
+ * 	is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode.
+ * 	RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command
+ * 	mode'.
+ *
+ * 	For some unknown reason, the RESET line isn't actually connected
+ * 	to anything. This means to reset the dongle to get it to a known
+ * 	state (9600 baud) you must drop DTR and RTS low, wait for the power
+ * 	capacitor to discharge, and then bring DTR (and RTS for data mode)
+ * 	high again, and wait for the capacitor to charge, the power supply
+ * 	to stabilise, and the oscillator clock to stabilise.
+ *
+ * 	Fortunately, if the current baudrate is known, the chipset can
+ * 	easily change speed by entering command mode without having to
+ * 	reset the dongle first.
+ *
+ * 	Major Components:
+ *
+ * 	- Vishay/Temic TOIM3232 SIR Endec to change RS232 pulse timings
+ * 	  to IRDA pulse timings
+ * 	- 3.6864MHz crystal to drive TOIM3232 clock oscillator
+ * 	- DM74lS04M Inverting Hex line buffer for RS232 input buffering
+ * 	  and level conversion
+ * 	- PJ2951AC 150mA voltage regulator
+ * 	- Vishay/Temic TFDS4500	SIR IRDA front-end transceiver

Subject: [TG3]: Add new hard_start_xmit

Support 5787 hardware TSO using a new flag TG3_FLG2_HW_TSO_2.

Since the TSO interface is slightly different and these chips have
finally fixed the 4GB DMA problem and do not have the 40-bit DMA
problem, a new hard_start_xmit is used for these chips. All previous
chips will use the old hard_start_xmit that is now renamed
tg3_start_xmit_dma_bug().

Subject: [TG3]: Add new one-shot MSI handler

Support one-shot MSI on 5787.

This one-shot MSI idea is credited to David Miller. In this mode, MSI
disables itself automatically after it is generated, saving the driver
a register access to disable it for NAPI.

Subject: [TG3]: nvram cleanup

Some nvram related cleanup:

1. Add a tg3_nvram_read_swab() since swabing the data is frequently
done.

2. Add a function to convert nvram address to physical address
instead of doing it in 2 separate places.

Subject: [WAN]: fix section mismatch warning in sbni

In latest -mm sbni gives following warning: WARNING:
drivers/net/wan/sbni.o - Section mismatch: reference to \ .init.data:
from .text between 'init_module' (at offset 0x14ef) and \
'cleanup_module'

The warning is caused by init_module() calling a function declared
__init.  Declare init_module() __init too to fix warning.

Subject: [TG3]: netif_carrier_off runs too early; could still be queued when
 init fails

Move the netif_carrier_off() call from tg3_init_one()->
tg3_init_link_config() to tg3_open() as is the convention for most other
network drivers.

I was getting a panic after a tg3 device failed to initialize due to DMA
failure.  The oops pointed to the link watch queue with spinlock debugging
enabled.  Without spinlock debugging, the Oops didn't occur.

I suspect that the link event was getting queued but not executed until
after the DMA test had failed and the device was freed.  The link event was
then operating on freed memory, which could contain anything.  With this
patch applied, the Oops no longer occurs.

[ Based upon feedback from Michael Chan, we move netif_carrier_off()
  to the end of tg3_init_one() instead of moving it to tg3_open() -DaveM ]

Subject: [NET]: Replace skb_pull/skb_postpull_rcsum with skb_pull_rcsum

We're now starting to have quite a number of places that do skb_pull
followed immediately by an skb_postpull_rcsum.  We can merge these two
operations into one function with skb_pull_rcsum.  This makes sense
since most pull operations on receive skb's need to update the
checksum.

I've decided to make this out-of-line since it is fairly big and the
fast path where hardware checksums are enabled need to call
csum_partial anyway.

Since this is a brand new function we get to add an extra check on the
len argument.  As it is most callers of skb_pull ignore its return
value which essentially means that there is no check on the len
argument.
