Add support for IPv6 TSO
Re-factor the Tx code with smaller functions to increase readability.
Add linearization code in case packet is too fragmented for the
microcode to handle.

The TPA stands for Transparent Packet Aggregation. When enabled, the FW
aggregate in-order TCP packets according to the 4-tuple match and sends
1 big packet to the driver. This packet is stored on an SGL in which
each SGE is 1 page. The FW also implements a timeout algorithm and it
honors all TCP flag, including the push flag as a trigger to halt
aggregation.
After receiving Ben Hutchings comments, we also added ethtool support,
so now, thanks to Ben's patch, when forwarding is enabled, our
aggregation is turned off using the LRO flags.

To avoid race conditions with link up/down and driver up/down - the
statistics handling was re-written in a form of state machine.
Also supporting statistics for 57711

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

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

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")
