During probe, the driver is incorrectly switching the power to Vaux on
the 5717 and later devices. At this point, we are in D0 state and
drawing maximum power. We also definitely have Vmain available. It
doesn't make sense to switch to Vaux since it has a lesser maximum power
draw and we might go over the limit. On a new system, we observe that
not all ports are recognized in some of the slots with this call in
place.

After this earlier commit to simplify probing:
commit 4bd9b0fffb193d2e288f67f81821af32df8d4349
cnic, bnx2x, bnx2: Simplify cnic probing.
we can now reliably receive netdev events and we can simplify the handling
of these events. We now remove the logic that tries to handle missed
NETDEV_REGISTER events.
This change will allow cleanup to be simplified in the next patch. We can
now rely on the play back of netdev events during
unregister_netdevice_notifier() to cleanup the structures.

bgmac uses bcm47xx_nvram.h which is only available when BCM47XX was

There is no need to initialize the dump data with zeros.
data is allocated with vzalloc, so it's already zero-filled.
More importantly, the memset is harmful, because dump->len (the length

size is determined by asking the driver's .get_dump_flag method).

When the EEH error is the result of a fenced host bridge, MMIO accesses
can be very slow (milliseconds) to timeout and return all 1's,
thus causing the driver various timeout loops to take way too long and
trigger soft-lockup warnings (in addition to taking minutes to recover).
It might be worthwhile to check if for any of these cases, ffffffff is
a valid possible value, and if not, bail early since that means the HW
is either gone or isolated. In the meantime, checking that the PCI channel
is offline would be workaround of the problem.

The ath9k Kconfig conflict was a change of a Kconfig option name right

The xen-netback conflict was overlapping changes involving the
handling of the notify list in xen_netbk_rx_action().
Batman conflict resolution provided by Antonio Quartulli, basically
keep everything in both conflict hunks.
The nl80211 conflict is a little more involved. In 'net' we added a
dynamic memory allocation to nl80211_dump_wiphy() to fix a race that
Linus reported. Meanwhile in 'net-next' the handlers were converted
to use pre and post doit handlers which use a flag to determine
whether to hold the RTNL mutex around the operation.
However, the dump handlers to not use this logic. Instead they have
to explicitly do the locking. There were apparent bugs in the
conversion of nl80211_dump_wiphy() in that we were not dropping the
RTNL mutex in all the return paths, and it seems we very much should
be doing so. So I fixed that whilst handling the overlapping changes.
To simplify the initial returns, I take the RTNL mutex after we try
to allocate 'tb'.

The current tg3 code assumes the pci_error_handlers to be always called
in sequence. In particular, during ->error_detected(), NAPI is disabled
and the device is shutdown. The device is later reset and NAPI
re-enabled in ->slot_reset() and ->resume().
In EEH, if more than 6 errors are detected in a hour, only
->error_detected() will be called. This will leave the driver in an
inconsistent state as NAPI is disabled but netif_running state is still
true. When the device is later closed, we'll try to disable NAPI again
and it will loop forever.
We fix this by closing the device if we encounter any error conditions
during the normal sequence of the pci_error_handlers.

This patch adds support for the Broadcom BCM6345 SoC Ethernet. BCM6345
has a slightly different and older DMA engine which requires the
following modifications:
- the width of the DMA channels on BCM6345 is 64 bytes vs 16 bytes,
which means that the helpers enet_dma{c,s} need to account for this
channel width and we can no longer use macros
- BCM6345 DMA engine does not have any internal SRAM for transfering
buffers
- BCM6345 buffer allocation and flow control is not per-channel but
global (done in RSET_ENETDMA)
- the DMA engine bits are right-shifted by 3 compared to other DMA
generations
- the DMA enable/interrupt masks are a little different (we need to
enabled more bits for 6345)
- some register have the same meaning but are offsetted in the ENET_DMAC
space so a lookup table is required to return the proper offset
The MAC itself is identical and requires no modifications to work.

Some systems that don't need wake-on-lan may choose to power down the
chip on system standby. Upon resume, the power on causes the boot code
to startup and initialize the hardware. On one new platform, this is
causing the device to go into a bad state due to a race between the
driver and boot code, once every several hundred resumes. The same race
exists on open since we come up from a power on.
This patch adds a wait for boot code signature at the beginning of
tg3_init_hw() which is common to both cases. If there has not been a
power-off or the boot code has already completed, the signature will be
present and poll_fw() returns immediately. Also return immediately if
the device does not have firmware.

Newer Broadcom BCM63xx SoCs: 6328, 6362 and 6368 have an integrated switch
which needs to be driven slightly differently from the traditional
external switches. This patch introduces changes in arch/mips/bcm63xx in order
to:
- register a bcm63xx_enetsw driver instead of bcm63xx_enet driver
- update DMA channels configuration & state RAM base addresses
- add a new platform data configuration knob to define the number of
ports per switch/device and force link on some ports
- define the required switch registers
On the driver side, the following changes are required:
- the switch ports need to be polled to ensure the link is up and
running and RX/TX can properly work
- basic switch configuration needs to be performed for the switch to
forward packets to the CPU
- update the MIB counters since the integrated

The current bcm63xx_enet driver always uses bcmenet_shared_base whenever
it needs to access DMA channel configuration space or access the DMA
channel state RAM. Split these register in 3 parts to be more accurate:
- global DMA configuration
- per DMA channel configuration space
- per DMA channel state RAM space
This is preliminary to support new chips where the global DMA
configuration remains the same, but there is a varying number of DMA
channels located at a different memory offset.

It was recently found out that GSO on 57710/57711 was broken, due to packets
being sent without a valid IP checksum.
Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this
issue, but failed to set the correct IP checksum when receiving GSO packets
via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed
to calculate IP checksum were erroneously set in the incorrect
buffer descriptor.
This patch re-enables GSO in said scenario for 57710/57711 chips.

FW was initialized with data from wrong header, this caused TSO packets
have wrong IP csum.

Pci_enable_device() will set device pm state to D0, so
it's no need to do it again in tg3_init_one().

If PCIe supports PM capabilities, bnx2x will always claim eeprom is accessible
as PCI_D0 is zero.

This patch includes a few changes that change the driver's flow without truly
changing anything in its functionality - use usleep_range for short sleeps
instead of msleep and initialize Tx consumer during initialization for better
information during errors.

This patch revises many bnx2x prints - mainly fixing print typos and
adding some new debug prints (mostly for parity issues).

This patch introduces several small changes to the driver, none which actually
change any flow:
1. Removes prototypes of unexisting functions and unused defines.
2. Fixes alignment and spacing issues.
3. Changes numeric usage into constants.
4. Remove unnecessary parenthesis.

The bnx2x_select_queue() was using __skb_tx_hash() to select the
transmit queue, totally ignoring XPS settings, while XPS can help
performance quite significantly, so change the bnx2x_select_queue()
to use __dev_pick_tx() instead which will use XPS if configured.
