New FW/HSI (7.0):
- Added support to 578xx chips
- Improved HSI - much less driver's direct access to the FW internal
memory needed.
New implementation of the HSI handling layer in the bnx2x (bnx2x_sp.c):
- Introduced chip dependent objects that have chip independent interfaces
for configuration of MACs, multicast addresses, Rx mode, indirection table,
fast path queues and function initialization/cleanup.
- Objects functionality is based on the private function pointers, which
allows not only a per-chip but also PF/VF differentiation while still
preserving the same interface towards the driver.
- Objects interface is not influenced by the HSI changes which do not require
providing new parameters keeping the code outside the bnx2x_sp.c invariant
with regard to such HSI chnages.
Changes in a CNIC, bnx2fc and bnx2i modules due to the new HSI.

Moved the HSI dependent slow path code to a separate file.
Currently it contains the implementation of MACs, Rx mode,
multicast addresses, indirection table, fast path queue and function
configuration code.

This updates bnx2x to use the ethtool_cmd_speed() family of functions
(see b11f8d8c in 2.6.27-rc3 aka. "ethtool: Expand ethtool_cmd.speed to
32 bits") to get and set the link speed via ethtool. This allows to
avoid manually accessing ethtool_cmd's speed_hi field.

When physical identification of an adapter is done by toggling the
mechanism on and off through software utilizing the set_phys_id operation,
it is done with a fixed duration for both on and off states. Some drivers
may want to set a custom duration for the on/off intervals. This patch
changes the API so the return code from the driver's entry point when it
is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to
cycle the on/off states, and updates the drivers that have already been
converted to use the new set_phys_id and use the synchronous method for
identifying an adapter.
The physical identification frequency set in the updated drivers is based
on how it was done prior to the introduction of set_phys_id.
Compile tested only. Also fixes a compiler warning in sfc.
v2: drivers do not return -EINVAL for ETHOOL_ID_ACTIVE
v3: fold patchset into single patch and cleanup per Ben's feedback

Since ndo_fix_features callback is postponing features change when
bp->recovery_state != BNX2X_RECOVERY_DONE, netdev_update_features()
has to be called again when this condition changes. Previously,
ethtool_ops->set_flags callback returned -EBUSY in that case
(it's not possible in the new model).

v5: - don't delay set_features, as it's rtnl_locked - same as recovery process
v4: - complete bp->rx_csum -> NETIF_F_RXCSUM conversion
- add check for failed ndo_set_features in ndo_open callback
v3: - include NETIF_F_LRO in hw_features
- don't call netdev_update_features() if bnx2x_nic_load() failed
v2: - comment in ndo_fix_features callback

Fixes in registers dump:
- Properly calculate dump length for 57712.
- Prevent HW blocks parity attentions when dumping registers in order to
prevent false parity errors handling.
- Update the bnx2x_dump.h file: old one had a few bugs that could cause
fatal HW error as a result of a registers dump.

NIC partitioning is another flavor of multi function - having few
PCI functions share the same physical port. Unlike the currently
supported mode of multi-function which depends on the switch
configuration and uses outer-VLAN, the NPAR mode is switch independent
and uses the MAC addresses to distribute incoming packets to the different
functions. This patch adds the specific HW setting of the NPAR mode
and some distinctions between switch dependent (SD) and
switch independent (SI) multi-function (MF) modes where the configuration
is not the same.

According to Eric's suggestion:
Disable local BHes to prevent a dead-lock situation between sch_direct_xmit()
(Soft_IRQ context) and bnx2x_tx_int (called by bnx2x_run_loopback() - syscall
context), as both are taking a netif_tx_lock().
