With a bit of code moving to rt2x00lib within the
TX and RX paths we can now remove a lot of EXPORT_SYMBOL_GPL()
statements. This cleans up the interface between rt2x00lib
and the drivers and has the additional benefit that rt2x00pci
and rt2x00usb are trimmed down in size as well since they
have less to do.

The current PCI drivers require a lot of pre-allocated DMA buffers. Reduce this
by using dynamically mapped skb's (using pci_map_single) instead of the pre-
allocated DMA buffers that are allocated at device start-up time.

At the same time move common RX path code into rt2x00lib from rt2x00pci and
rt2x00usb, as the RX paths now are now almost the same.

At the same time clean up the device administration a bit, by storing a pointer
to struct device instead of a void pointer that is dependent on the type of
device. The normal PCI and USB subsystem provided macros can be used to convert
the device pointer to the right type.

The latest trace about usage of this driver I found was an (unanswered)
request for help by a user trying to get it working reliably five years
ago with kernel 2.4 .

And even if it was still working the use cases of this driver (requiring
both the hardware and someone providing this kind of wireless network)
have become practically nonexisting.

This patch therefore removes the strip driver.

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.

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")
