4d295db0ef bnx2x: Supporting BCM8727 PHY
Adding support for BCM8727 - a dual port SFP+ PHY. That includes verification of
the optic module vendor and part number - the list of approved modules resides
on the nvram and the module is verified by the FW. Since not all users would
like to use this verification feature, it can be disabled. The default behavior
is to issue a warning if the module is not approved, but still allow using it -
but it is also possible to disable the link if the module is not approved.

279abdf59c bnx2x: Stop management traffic in loopback test
Since management traffic cannot go on the wire while configured to loopback,
simply stop it to avoid race condition when the MAC is set to loopback in the
middle of a packet

589abe3a0f bnx2x: Supporting BCM8726 PHY
Also adding the ability to recognize the optic module and disable it if it is
not authorized for safety reasons - since this feature might upset some users
which are willing to take the risk, it is optional and can be disabled by
setting an nvram bit (or a trivial driver patch to set this bit).
This dual port PHY requires special handling if the ports are swapped.

8c99e7b043 bnx2x: Pause settings
Pause settings
- 1G pause was not working due to missing write to the emac block
  (TX_MODE_FLOW_EN)
- The flow control should use the negotiated result (after autoneg) so
  we should save both the requested autoneg and the result
- The HW credits with flow control at 1G speed were not optimized and
  caused low throughput
- It is recommended to turn off flow control if the MTU is bigger than
  5000B due to internal buffers size

57963ed94c bnx2x: Link order with external PHY
Link order with external PHY
When external PHY exists (second chip with the PHY to translate to
another physical medium) the link with the eternal PHY and the network
should be established before setting the link between the 5771x and the
PHY. This is the right order and it is important when using autoneg -
the link to the network should use the autoneg and the link between the
two chips should be forced to the network result.

da5a662a23 bnx2x: Load/Unload under traffic
Load/Unload under traffic
Few issues were found when loading and unloading under traffic:
- When receiving Tx interrupt call netif_wake_queue if the queue is
  stopped but the state is open
- Check that interrupts are enabled before doing anything else on the
  msix_fp_int function
- In nic_load, enable the interrupts only when needed and ready for it
- Function stop_leading returns status since it can fail
- Add 1ms delay when unloading the driver to validate that there are no
  open transactions that already started by the FW
- Splitting the "has work" function into Tx and Rx so the same function
  will be used on unload and interrupts
- Do not request for WoL if only resetting the device (save the time
  that it takes the FW to set the link after reset)
- Fixing the device reset after iSCSI boot and before driver load - all
  internal buffers must be cleared before the driver is loaded

Statistics
- Making sure that each drop is accounted for in the driver statistics
- Clearing the FW statistics when driver is loaded to prevent
  inconsistency with HW statistics
- Once error is detected (bnx2x_panic_dump), stop the statistics
  before other actions (currently it is stopped last and can corrupt
  the data) - Adding HW checksum error counter to the statistics
- Removing unused variable stats_ticks
- Using macros instead of magic numbers to indicate which statistics are
  shared per port and which are per function

34f80b04f3 bnx2x: Add support for BCM57711 HW
Supporting the 57711 and 57711E - refers to in the code as E1H. The
57710 is referred to as E1.

To support the new members in the family, the bnx2x structure was
divided to 3 parts: common, port and function. These changes caused some
rearrangement in the bnx2x.h file.

A set of accessories macros were added to make access to the bnx2x
structure more readable

c18487ee24 bnx2x: New link code
New Link code:
Moving all the link related code (including the calculations, the
initialization of the MAC and PHY and the external PHY's code) into
a separated file. The changes from the code that used to be part of
bnx2x.c (now called bnx2x_main.c) are:
- Using separate structures for link inputs and link outputs to clearly 
  identify what was configured and what is the outcome
- Adding code to read external PHY FW version and print it as part of 
  ethtool -i
- Adding code to upgrade external PHY FW from ethtool -E with special 
  magic number - Changing the link down indication to ERR level
- Adding a lock on all PHY access to prevent an interrupt and 
  setting changes to overlap
- Adding support for emulation and FPGA (small chunk of code that really 
  helps in the lab) - Adding support for 1G on BCM8706 PHY
- Adding clear debug print incase of fan failure (the PHY type is now 
  "failure")

f14106478e [BNX2X]: Correct Link management
Properly protect PHY access between two devices on the same board with
a HW lock.

Use GPIO to clear all previous configurations before changing link
parameters.

Shut down the external PHY in case of fan failure.

Reducing the MDC/MDIO clock to 2.5MHz due to problems with some
devices.

Resolve the flow control response according to autoneg with external
PHY.

Unmasking all PHY interrupts in single write to prevent a race in the
interrupts order.

LASI indication fixes to work with peculiarities of PHYs.

Disable MAC RX to avoid a HW bug when closing the MAC under traffic.

Disable parallel detection on HiGig due to HW limitation.

Updating the shared memory structure to work with the current
bootcode.
