Yuval Mintz 639d65b855 bnx2x: semi-Semantic changes
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.

Yuval Mintz 3cdeec22e4 bnx2x: Semantic removal and beautification
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.

Eric Dumazet ada7c19e6d bnx2x: use XPS if possible for bnx2x_select_queue instead of pure hash
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.

Yuval Mintz 3fb43eb20a bnx2x: Change to D3hot only on removal
This changes the PCI power management scheme of the bnx2x driver to be similar
to those of most network drivers - the driver will now changes the power state
into D3hot whenever the driver will be removed, instead of whenever an
interface is unloaded.

This change enables the driver to access its eeprom via ethtool callbacks
even when interfaces are unloaded (such access requires the function to be
in D0active).

Yuval Mintz b030ed2fdc bnx2x: Implement PCI shutdown
Implement the PCI shutdown callback to support un-orderly shutdown, i.e.,
shutdowns in which the remove callback will not be called.

Due to the lack of this functionality, when an un-orderly shutdown occurred,
it was possible for wake-on-lan to remain disabled.

This is now fixed as the callback introduces the correct place in which
`system_state' can be queried and wake-on-lan be configured accordingly.

Yuval Mintz e68072ef46 bnx2x: Wait for MCP validity during AER
During PCIe advanced error recovery, the secondary bus reset will cause FW
to reset; This will cause the shared memory between it and the driver to be
invalidated.

During the driver's recovery flow, the driver should not make any assumption
on the validity of that memory and instead re-initialize it.

This also removes a redundant re-initialization of a previously
initialized mutex.

Dmitry Kravkov 178135c116 bnx2x: Link-flap avoidance in switch dependent mode
As part of the previous unload flow, probed devices will reset the chip
in order to clean the remains of the UNDI driver.
As a result, it's possible for the FW to toggle the link.

This toggling can prove fatal, as long periods without link can cause the
filesystem mount to fail as the storage protocol timeouts. This has been
observed against particular switches with long link re-establishment time.

This patch informs FW during the reset period that the link should not
be toggled - the FW will keep it alive until some interface will load and claim
the link as its own.

Nithin Sujir fb03a43f5f tg3: Ensure boot code has completed initialization before accessing hardware
After resetting the device, the driver waits for a signature to be
updated to know that firmware has completed initialization. However, the
call to tg3_poll_fw() is being done too late and we're writing to the
GRC_MODE register before it has completely initialized, causing
contention with firmware.  This logic has existed since day one but is
causing PCIE link to go down randomly at startup on one platform once
every few hundred reboots.

Move the tg3_poll_fw() up to before we write to the GRC_MODE register
after reset.

Starting with commit 91226790bb
`bnx2x: use FW 7.8.17', the bnx2x driver no longer requests the FW to perform

This behaviour needs to be revised for 57710/57711 chips -
when using GSO, if the driver will not set the IP checksum flag then packets
will be transmitted by the chip without a valid IP checksum, resulting in
a drop of all such packets on the receiver-side.

The firmware supports a maximum of 4K FCoE exchanges. In 4-port devices,
or when working in multi-function mode, this resource needs to be distributed
between the various possible FCoE functions.

This information needs to be calculated by bnx2x and propagated into bnx2fc
via cnic. bnx2fc can then use this value to calculate corresponding xid
resources instead of using global constants.

Yuval Mintz ecf01c22be bnx2x: Prevent NULL pointer dereference in kdump
In scenarios in which a previous driver was removed without proper cleanup
(e.g., kdump), it is possible for the chip to generate an interrupt without
any apparent reason once interrupts are requested.

Due to an erroneous initialization of resources, some of the bnx2x structs
which are required for interrupt handling are initialized only after an
interface's interrupt is requested from the OS.

As a result, once such a spurious interrupt occurs, it will cause a NULL
pointer dereference - the driver will access those structs in its interrupt
handling routine.

This patch change the interrupt request scheme so that bnx2x would only
request interrupts from the kernel after it has finished initializing
all the inner structs required for interrupt handling.

Yuval Mintz 70632d0afe bnx2x: Allow recovery from second slot reset
As part of PCIe Advanced Error Reporting flow, if a fatal PCI error occurs,
the AER driver will cause bnx2x's PCI-core to reset. The driver's PCI error
handlers will in turn restore the PCI configuration space values by calling
`pci_restore_state'.

However, as bnx2x does not save the PCI configuration after restoration,
An additional fatal PCI error will leave the function in an unstable state
until reboot, as the registers in the PCI configuration space will contain
reset values.

Yuval Mintz 2c2d06d512 bnx2x: prevent GRO false checksum claims
This patch introduces a more robust error handling flow in case of incorrect
behaviour by the FW when passing on GRO aggregations.

Although this should never happen (i.e., this is merely a theoretical fix),
if the bnx2x driver was to receive a GRO from FW with protocol other than
IPv4/IPv6, the driver would falsely claim to have performed partial
checksum and set various incorrect fields in the skb header.

Current behaviour of the bnx2x driver (i.e., print an error) is insufficient.
This patch remedies this by simply preventing the false claims.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN
interface changes by Patrick McHardy in net-next.

An IGB conflict existed because in 'net' the build_skb() support was
reverted, and in 'net-next' there was a comment style fix within that
code.

Several batman-adv conflicts were resolved by making sure that all
calls to batadv_is_my_mac() are changed to have a new bat_priv first
argument.

Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO

Dmitry Kravkov d46f7c4df3 bnx2x: Prevent UNDI FW illegal host access
When loading after UNDI (e.g., Boot from SAN) the UNDI does not
gracefully yield its resources; The bnx2x driver handles that release
itself.

During the manipulation required to release those resources, it's possible
for the UNDI to try and write to memory regions which are no longer accessible,
causing the PCI bus to prevent further writes from the chip.

This would in turn cause DMAE timeouts later on in the driver, as the driver
will be unable to use the chip's DMA engines.

This patch prevents the chip from actually writing through the PCI bus
in said scenario, thus allowing the release without the unfortunate by-product.

The cnic module is responsible for initializing various bnx2x structs
via callbacks provided by the bnx2x module.
One such struct is the queue object for the FCoE queue.

If a device is working in AFEX mode and its configuration allows FCoE yet
the cnic module is not loaded, it's very likely a null pointer dereference
will occur, as the bnx2x will erroneously access the FCoE's queue object.

Prevent said access until cnic properly registers itself.

Nithin Sujir fdad8de467 tg3: Pull the phy advertised speed and flow control settings on driver load
Normally on driver load, we set the default settings for speed and flow
control. However, if the default setting is not compatible with the current link
state, we would autonegotiate and cause a link flap. To avoid this, we
pull the current advertised settings into the config.

A second scenario is if a user changes the speed/duplex/fc settings when
the interface is down. In this case we must not pull the settings from
the phy and overwrite user settings. We avoid that by checking the
USER_CONFIGURED flag.

Nithin Sujir 942d1af00a tg3: Add support for link flap avoidance
This patch and the following two patches add support for link flap avoidance
by maintaining the link on power down. This feature is required for
management capable devices to have the management connection
uninterrupted on driver reload, reboot and interface up/down.

The other pros of this feature are
 - It speeds up boot up time by several seconds as DHCP addresses can be
   acquired faster.
 - It avoids lengthy Spanning Tree delay.

On powerup the hardware brings up the phy with default settings. If the
link is not up, the management software configures the phy to gigabit
and starts autonegotiate. Subsequently, as long as the link is up, the
driver and management refrain from resetting and/or changing any
configuration that the link depends on.

The LNK_FLAP_AVOID setting is an NVRAM user configurable bit and is
disabled by default.  If this setting is enabled, we skip powering down
the phy and resetting it.

A second NVRAM setting is 1G_ON_VAUX_OK (off by default). This adds
support for gigabit link speed when device is on auxiliary power.

Limit the hardware's reported firmware string length (max 255 bytes) to

truncate the formatted firmware string instead of potentially overwriting
portions of the tg3 struct.

Nithin Sujir 7c6cdead7c tg3: 5715 does not link up when autoneg off
Commit d13ba512cb ("tg3: Remove
SPEED_UNKNOWN checks") cleaned up the autoneg advertisement by
removing some dead code. One effect of this change was that the
advertisement register would not be updated if autoneg is turned off.

This exposed a bug on the 5715 device w.r.t linking. The 5715 defaults
to advertise only 10Mb Full duplex. But with autoneg disabled, it needs
the configured speed enabled in the advertisement register to link up.

This patch adds the work around to advertise all speeds on the 5715 when
autoneg is disabled.

This patch prevents said message.

Ariel Elior 005a07baa1 bnx2x: Set ethtool ops for vfs
Virtual functions don't have access to HW registers, therefore most ethtool ops
are forbidden to them. Instead of checking in each op whether the device being
driven is a virtual function or a physical function, this patch creates a
separate ethtool ops struct for virtual functions and uses it to initialize
the ethtool ops of the driver in case it is driving a virtual function device.

Nithin Sujir 84421b99ce tg3: Update link_up flag for phylib devices
Commit f4a46d1f46 introduced a bug where
the ifconfig stats would remain 0 for phylib devices. This is due to
tp->link_up flag never becoming true causing tg3_periodic_fetch_stats()
to return.

The link_up flag was being updated in tg3_test_and_report_link_chg()
after setting up the phy. This function however, is not called for
phylib devices since the driver does not do the phy setup.

This patch moves the link_up flag update into the common
tg3_link_report() function that gets called for phylib devices as well
for non phylib devices when the link state changes.

To avoid updating link_up twice, we replace tg3_carrier_...() calls that
are followed by tg3_link_report(), with netif_carrier_...(). We can then
remove the unused tg3_carrier_on() function.

Yaniv Rosner 5f3347e6e7 bnx2x: Fix intermittent long KR2 link up time
When a KR2 device is connected to a KR link-partner, sometimes it requires
disabling KR2 for the link to come up. To get a KR2 link up later, in case no
base pages are seen, the KR2 is restored. The problem was that some link
partners cleared their advertised BP/NP after around two seconds, causing the
driver to disable/enable KR2 link all the time.
The fix was to wait at least 5 seconds before checking KR2 recovery.

The current firmware header parsing is complicated due to interpreting it as a
u32 array and accessing header members via array offsets. Add tg3_firmware_hdr
structure to access the firmware fields instead of hardcoding offsets. The same
header format will be used for individual firmware fragments in the 57766.

The fw_hdr and tg3 structures have all the information required for
loading the fw. Remove the redundant fw_info structure and pass fw_hdr
instead.

Joe Perches 4153577a8d tg3: Use different macros for pci_chip_rev_id accesses
Upper case macros for various chip attributes are slightly
difficult to read and are a bit out of characterto the other
tg3_<foo> attribute functions.

Convert:

GET_ASIC_REV(tp->pci_chip_rev_id)       -> tg3_asic_rev(tp)
GET_CHIP_REV(tp->pci_chip_rev_id)       -> tg3_chip_rev(tp)

Remove:
GET_METAL_REV(tp->pci_chip_rev_id)      -> tg3_metal_rev(tp) (unused)

Add:
tg3_chip_rev_id(tp) for tp->pci_chip_rev_id so access styles
are similar to tg3_asic_rev and tg3_chip_rev.

These macros are not converted to static inline functions
because gcc (tested with 4.7.2) is currently unable to
optimize the object code it produces the same way and code
is otherwise larger.

Matt Carlson d3f677afb8 tg3: Add 57766 device support.
The patch also adds a couple of fixes

 - For the 57766 and non Ax versions of 57765, bootcode needs to setup
   the PCIE Fast Training Sequence (FTS) value to prevent transmit hangs.
   Unfortunately, it does not have enough room in the selfboot case (i.e.
   devices with no NVRAM).  The driver needs to implement this.

 - For performance reasons, the 2k DMA engine mode on the 57766 should
   be enabled and dma size limited to 2k for standard sized packets.

This core does not use a firmware or an eeprom.

Ariel Elior 4c133c39ae bnx2x: SR-IOV version compatibility bugfix
When posting a message on the bulletin board, the PF calculates crc
over the message and places the result in the message. When the VF
samples the Bulletin Board it copies the message aside and validates
this crc. The length of the message is crucial here and must be the
same in both parties. Since the PF is running in the Hypervisor and
the VF is running in a Vm, they can possibly be of different versions.
As the Bulletin Board is designed to grow forward in future versions,
in the VF the length must not be the size of the message structure
but instead it should be a field in the message itself.

In INTA mode, cnic and bnx2x share the same IRQ.  During chip reset,
for example, cnic will stop servicing IRQs after it has shutdown the
cnic hardware resources.  However, the shared IRQ is still active as
bnx2x needs to finish the reset.  There is a window when bnx2x does
not know that cnic is no longer handling IRQ and things don't always
work properly.

Add a flag to tell bnx2x that cnic is handling IRQ.  The flag is set
before the first cnic IRQ is expected and cleared when no more cnic
IRQs are expected, so there should be no race conditions.

Since submit 621b4d6 the bnx2x driver support FW GRO.
However, when using the device with GRO enabled in bridging
scenarios throughput is very low, as the bridge expects all
incoming packets to be passed with CHECKSUM_PARTIAL -
a demand which is satisfied by the SW GRO implementation,
but was missed in the bnx2x driver implementation (which returned
CHECKSUM_UNNECESSARY).

Now, given that the traffic is supported by FW GRO (TCP/IP),
the bnx2x driver calculates the pseudo checksum by itself,
passing skbs with CHECKSUM_PARTIAL and giving a much better
throughput when receiving GRO traffic.

Florian Fainelli f9a8f83b04 net: phy: remove flags argument from phy_{attach, connect, connect_direct}
The flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.

As part of the previous driver unload flow, whenever bnx2x is
loaded after the UNDI driver it closes all Rx traffic.
However, this leads to management traffic also being stopped until

Rafał Miłecki dd4544f054 bgmac: driver for GBit MAC core on BCMA bus
BCMA is a Broadcom specific bus with devices AKA cores. All recent BCMA
based SoCs have gigabit ethernet provided by the GBit MAC core. This
patch adds driver for such a cores registering itself as a netdev. It
has been tested on a BCM4706 and BCM4718 chipsets.

In the kernel tree there is already b44 driver which has some common
things with bgmac, however there are many differences that has led to
the decision or writing a new driver:
1) GBit MAC cores appear on BCMA bus (not SSB as in case of b44)
2) There is 64bit DMA engine which differs from 32bit one
3) There is no CAM (Content Addressable Memory) in GBit MAC
4) We have 4 TX queues on GBit MAC devices (instead of 1)
5) Many registers have different addresses/values
6) RX header flags are also different

The driver in it's state is functional how, however there is of course
place for improvements:
1) Supporting more net_device_ops
2) SUpporting more ethtool_ops
3) Unaligned addressing in DMA
4) Writing separated PHY driver

it would like to have. In the response the PF either ratifies the
request, or denies it and supplies the maximum values supported.
The VF may then attempt another acquire request.
This patch adds the bnx2x_vfpf.c file which contains the
implementation of the VF to PF hardware channel.

Ariel Elior 1ab4434c64 bnx2x: Support probing and removing of VF device
To support probing and removing of a bnx2x virtual function
the following were added:
1. add bnx2x_vfpf.h: defines the VF to PF channel
2. add bnx2x_sriov.h: header for bnx2x SR-IOV functionality
3. enumerate VF hw types (identify VFs)
4. if driving a VF, map VF bar
5. if driving a VF, allocate Vf to PF channel
6. refactor interrupt flows to include VF

Barak Witkowski c63da990cd bnx2x: Prevent link flaps when booting from SAN.
It is possible that the driver is configured to operate with a certain
link configuration which differs from the link's configuration during
boot from SAN - this would cause the driver to flap the link.

Said flap may be missed by specific switches, causing dcbx convergence
to be too long and boot sequence to fail. Convergence is longer because
switch ignores new dcbx packets due to counters mismatch, as only host
side reset the counters due to the link flap.

This patch causes the driver to ignore user's initial configuration during
boot from SAN, and continues with the existing link configuration.

This patch adds the ptp_caps structure, ptp api implementation,
reference clock read and register/unregister functions.  All the basic
clock operations as described in Documentation/ptp/ptp.txt are
supported.

Frequency adjustment is performed using hardware with a 24 bit
accumulator and a programmable correction value. On each clk, the
correction value gets added to the accumulator and when it overflows,
the time counter is incremented/decremented and the accumulator reset.

So conversion from ppb to correction value is
	ppb * (1 << 24) / 1000000000

Yaniv Rosner 503976e998 bnx2x: Cosmetic changes
This patch makes some cosmetic changes to the code:
1. Code alignment.
2. Merge read-modify-write into a single function (read_or_write /
read_and_write).
3. Merge several write registers into a for-loop write using a static array.
4. Remove empty lines.
5. Fix comments.

Yaniv Rosner 8203c4b6c9 bnx2x: Always take PHY lock
Taking PHY lock is not required on some older designs, but we are removing this
complication and always taking it since it is always required on newer designs
and does not worth the code complication on the older boards.

Taking PHY lock was initially required only on specific boards which had their
MDC/MDIO bus crossed, but since this lock is now always required, for example,
when NCSI is present, the PHY lock will always be taken.

Yaniv Rosner 5a1fbf4046 bnx2x: Fix SFP+ current leakage
Per measurements, the SFP+ suffered from small current leakage in two cases:
 - When no module was plugged and TX laser was disabled. The fix was to enable
   it, and when module is plugged in, check if it needs to be disabled.
 - When over-current event occurs due to invalid SFP+ module, the HW basically
   shuts down the current for this module, but the SW needs to complete this
   by issuing a power down via a GPIO.

Yaniv Rosner 55386fe883 bnx2x: Change MDIO clock settings
When drivers works on top of an old bootcode, it is theoretically subjected to
MDC/MDIO failures since the MDIO clock is set in the beginning of each sequence,
rather than per CL45 command. On rare cases an old bootcodes may change that in
the middle, so to address that, the MDIO clock is set for each CL45 access.
In addition, setting the MDIO clock is now done per EMAC base, and
not per port number, since a specific port can potentially use both EMACs for
different PHY accesses.
