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.

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.
Based upon a report from Stephen Rothwell.

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

This patch is int the new bnx2x_link files (C and H). The files are
still not used in this patch, only in the next one so the patch will
be small enough for the mailing list.
