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.

These are now defined in linux/mii.h and the bnx2x driver
defines different values which are shared with hardware
data structures.

So add a "BNX2X_" prefix to these macro names.

Minor code improvements
Small changes to make the code a little bit more efficient and mostly
more readable:
- Using unified macros for EMAC_RD/WR which looks like normal REG_RD/WR
- Removing the NIG_WR since it did nothing and was only confusing
- On bnx2x_panic_dump, print only the used parts of the rings
- define parameters only on the branch they are needed and not at the
  beginning of the function
- using NETIF_MSG_INTR and not private BNX2X_MSG_SP for debug prints

8073 PHY changes
The initial support we had for this PHY needs some serious changing. The
major change is that this PHY should be initialized only when the first
function is loaded and not for each function. The official SPI-ROM of
this PHY was released and it requires some changes in the initialization
code as well

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

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.

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
