This patch revises many bnx2x prints - mainly fixing print typos and
adding some new debug prints (mostly for parity issues).

In latest boards, the CHIP_METAL register contains an incorrect
revision value, so the correct one needs to be obtained in a
different manner.

Self-tests following boot from SAN have failed as the
UNDI driver might leave some NIG interrupt indications.
This patch does the clean-up, clearing those indications
and allowing the test to pass.

The FLR indication arrives as an attention from the management processor.
Upon VF flr all FLRed function in the indication have already been
released by Firmware and now we basically need to free the resources
allocated to those VFs, and clean any remainders from the device
(FLR final cleanup).

The VF driver will send an 'init' request as part of its nic load
flow. This message is used by the VF to publish the GPA's of its
status blocks, slow path ring and statistics buffer.
The PF driver notes all this down in the VF database, and also uses
this message to transfer the VF to VF_INIT state internally.

When A PF determines that it may have to manage SRIOV VFs it
allocates a database for this purpose. The database is intended to
keep track of the VF state, the resources allocated for each VF
(queues, interrupt vectors, etc), the state of the VF's queues.
When the VF loads the database is updated accordingly.
When A VF closes the database is consulted to determine which
resources need to be released (close queues against device, reclaim
interrupt vectors, etc).

Generally, the VF driver cannot access the chip, except by the
narrow window its BAR allows. Care had to be taken so the VF driver
will not reach code which accesses the chip elsewhere.
Refactor the nic_load flow into parts so it would be
easier to separate the VF-only logic from the PF-only logic.

Add the 'acquire' request to VF <-> PF channel and use it at
VF probe. In the acquire request the VF driver lists the resources
it would like to have. In the response the PF either ratifies the
request, or denies it and supplies the maximum values supported.
The VF may then attempt another acquire request.
This patch adds the bnx2x_vfpf.c file which contains the
implementation of the VF to PF hardware channel.

To support probing and removing of a bnx2x virtual function
the following were added:
1. add bnx2x_vfpf.h: defines the VF to PF channel
2. add bnx2x_sriov.h: header for bnx2x SR-IOV functionality
3. enumerate VF hw types (identify VFs)
4. if driving a VF, map VF bar
5. if driving a VF, allocate Vf to PF channel
6. refactor interrupt flows to include VF

If fan failure is detected, MCP prevents PCI I/O registers from being
mapped to the bar, causing a fatal error as driver is unaware.
This patch recognizes such an event occurred and gracefully terminates

This patch replaces the BCM_CNIC define with a flag which can change at run-time
and which does not use the CONFIG_CNIC kconfig option.
For the PF/hypervisor driver cnic is always supported, however allocation of
cnic resources and configuration of the HW for offload mode is done only when
the cnic module registers bnx2x.

The flow in which the bnx2x driver starts after a previous driver
has been terminated in an 'unclean' manner has several bugs and
FW risks, which makes it possible for the driver to fail after
boot-from-SAN or kdump.
This patch contains a revised flow which performs a safer
initialization, solving the possible crash scenarios.
Notice this patch contains lines with over 80 characters, as it
keeps print-strings in a single line.

Use hardware locks to protect resources common to several Physical Functions. In
a virtualized environment the RTNL lock only protects a PF's driver against
the PFs sharing it's VMs with regard to device resources. Other PFs may reside
in other VMs under other OSs, and are not subject to the lock. Such resources
which were previously protected implicitly by the RTNL lock must now be
protected explicitly with dedicated HW locks.
