042a53a9e4 net: skb_shared_info optimization
skb_dma_unmap() is quite expensive for small packets,
because we use two different cache lines from skb_shared_info.

One to access nr_frags, one to access dma_maps[0]

Instead of dma_maps being an array of MAX_SKB_FRAGS + 1 elements,
let dma_head alone in a new dma_head field, close to nr_frags,
to reduce cache lines misses.

Tested on my dev machine (bnx2 & tg3 adapters), nice speedup !

cdd0db058d net: dont update dev->trans_start
Second round of drivers for Gb cards (and NIU one I forgot in the 10GB round)

Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Drivers can avoid one cache miss
(on dev->trans_start) in their start_xmit() handler.

Exceptions are NETIF_F_LLTX drivers

daba2a631d tg3: Restore LAA sooner in shutdown sequence
After a shutdown reset, the LAA needs to be restored before posting the
post-reset signature in shared memory.  If the LAA is not restored
before then, the bootcode will assume the factory default MAC address
and WOL will not work with the LAA.

624f8e5082 tg3: Allow screaming interrupt detection
The tg3 driver's ISR is coded to accept interrupts as its own if the
status block tag does not equal the last tag the driver has seen.  The
last_tag field is updated from tg3_poll.  In a screaming interrupt
situation from another device sharing tg3's IRQ, tg3_poll does not get
a chance to be called, so the last_tag will always be out of sync with
the status block tag.  Consequently, the driver will continually
declare the screaming interrupts as its own, thus thwarting the
screaming interrupt detection logic.

This patch solves the problem by creating a new last_irq_tag member and
recording the status block tag in the ISR.  The ISR then checks the
last_irq_tag for interrupt ownership.

Many thanks to John Marvin for the detailed bug report and analysis and
Michael Chan for the bugfix.

0d489ffb76 tg3: fix big endian MAC address collection failure
We noticed on parisc that our broadcoms all swapped MAC addresses going
from 2.6.29 to 2.6.30-rc1:

Apr 11 07:48:24 ion kernel: eth0: Tigon3 [partno(BCM95700A6) rev 0105] (PCI:66MHz:64-bit) MAC address 00:30:6e:4b:15:59
Apr 13 07:34:34 ion kernel: eth0: Tigon3 [partno(BCM95700A6) rev 0105] (PCI:66MHz:64-bit) MAC address 00:00:59:15:4b:6e

The problem patch is:

commit 6d348f2c1e
Author: Matt Carlson <mcarlson@broadcom.com>
Date:   Wed Feb 25 14:25:52 2009 +0000

    tg3: Eliminate tg3_nvram_read_swab()

With the root cause being the use of memcpy to set the mac address:

   memcpy(&dev->dev_addr[0], ((char *)&hi) + 2, 2);
   memcpy(&dev->dev_addr[2], (char *)&lo, sizeof(lo));

This might work on little endian machines, but it can't on big endian
ones.  You have to use the original setting mechanism to be correct on
all architectures.

The attached patch fixes parisc.

6d348f2c1e tg3: Eliminate tg3_nvram_read_swab()
The remaining uses of tg3_nvram_read_swab() either intended to read the
data from NVRAM exactly as tg3_nvram_read_be32() did or hide deeper
interpretations of the data.  For the former case, a direct replacement
of tg3_nvram_read_swab() with tg3_nvram_read_be32() is in order.  For
the latter case, we remove tg3_nvram_read_swab() and document what the
code is really doing.

a9dc529dcd tg3: Correct NVRAM stream endian notations
Any software requesting NVRAM data as it exists on NVRAM is necessarily
requesting that the results be returned as a bytestream.  A bytestream
data read in from the device can also be thought to be in big endian
format.  Therefore, all the LE notations in the driver are mislabeled.
This patch converts all LE notations to BE notations, carefully
evaluating the surrounding code in the process.

This patch removes the blind byteswap of NVRAM data as it is read in.
To preserve the logic at the call sites, this patch also inverts every

confusing within tg3_nvram_read_le() (LE is a misnomer), but the reader

is still unchanged.

9e9fd12dc0 tg3: Fix firmware loading
This patch modifies how the tg3 driver handles device firmware.

The patch starts by consolidating David Woodhouse's earlier patch under
the same name.  Specifically, the patch moves the request_firmware call
into a separate tg3_request_firmware() function and calls that function
from tg3_open() rather than tg3_init_one().

The patch then goes on to limit the number of devices that will make
request_firmware calls.  The original firmware patch unnecessarily
requested TSO firmware for devices that did not need it.  This patch
reduces the set of devices making TSO firmware patches to approximately
the following device set : 5703, 5704, and 5705.

Finally, the patch reduces the effects of a request_firmware() failure.
For those devices that are requesting TSO firmware, the driver will turn
off the TSO capability.  If TSO firmware becomes available at a later
time, the device can be closed and then opened again to reacquire the
TSO capability.

69fc405318 tg3: Remove unused cfgspc device members
This patch removes the pci_bist and pci_hdr_type members from the
device structure and removes the code that references them.  They are
not really used.

The patch rounds out the changes by moving the pci_cmd member to plug
a structure hole that would have been created.  On 32-bit systems, this
movement removes a subsequent structure hole later in the structure. On
64-bit systems though, the movement merely consolidates two holes into
one larger hole.

2023276ebf tg3: WOL fixes
The first hunk of this patch inverts a flag that was accidentally
toggled as part of commit 0a459aac9d
("tg3: Allow WOL for phylib controlled Broadcom phys").

The second hunk of the patch removes the call to
device_may_wakeup() in the 5906 config detection path.  At the
point of the call, the driver shouldn't be querying for WOL
capability.  It should be detecting and setting it.

bc02ff95fe net: Refactor full duplex flow control resolution
These 4 drivers have identical full duplex flow control resolution
functions.  This patch changes them all to use one common function.

The function in question decides whether a device should enable TX and
RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this
should also be useful for other drivers.

e18ce34654 net: Move flow control definitions to mii.h
flags used within drivers for indicating tx and rx flow control are
defined in 4 drivers (and probably more), move these constants to mii.h.

The 3 SMSC drivers use the same constants (FLOW_CTRL_TX), but TG3 uses
TG3_FLOW_CTRL_TX, so this patch also renames the constants within TG3.

22435849a6 tg3: Allow GPHY powerdown on 5761
The ENABLE_APE flag tells the driver whether or not the device has an
Application Processing Engine (APE).  The APE does not need the PHY to
be powered unless it is running management firmware.  For backwards
compatibility, management firmware will still set the ENABLE_ASF bit.
Consequently, there is no reason to consider the ENABLE_APE flag when
deciding whether or not to power down the phy.

d5fe488a7b tg3: Embrace pci_ioremap_bar()
Per Dave Miller's suggestion, replace the remaining ioremap_nocache()
call with pci_ioremap_bar().  Remove the two IORESOURCE_MEM checks as
they are redundant.
