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

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

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")

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.
