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.

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.

This is the FW blob and the relevant definitions without any logic. It
also contains the minimal mandatory code changes to work with this FW
but it does not contain enabling of the new features that this FW
provides.

This FW is needed for:
- More efficient multi-queue
- per queue statistics
- Big-endian issue with MSI
- Improved pause response

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

ad8d394804 bnx2x: New init infrastructure
This new initialization code supports the 57711 HW. It also supports
the emulation and FPGA for the 57711 and 57710 initializations values
(very small amount of code which is very helpful in the lab - less
than 30 lines).

The initialization is done via DMAE after the DMAE block is ready -
before it is ready, some of the initialization is done via PCI
configuration transactions (referred to as indirect write).  A mutex
to protect the DMAE from being overlapped was added.  There are few
new registers which needs to be initialized by SW - the full comment
for those registers is added to the register file.  A place holder for
the 57711 (referred to as E1H) microcode was added- the microcode
itself is too big and it is split over the following 4 patches

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.
