Bug fix: Protect the statistics state machine state update with a
spinlock. Otherwise there was a race condition that would cause the
statistics to stay enabled despite the fact that they were disabled in
the LINK_DOWN event handler.

This patch introduces the parity errors handling code for 57710 and 57711 chips.
HW is configured to stop all DMA transactions to the host and sending packets to the network
once parity error is detected, which is meant to prevent silent data corruption.
At the same time HW generates the attention interrupt to every function of the device where parity
has been detected so that driver can start the recovery flow.
The recovery is actually resetting the chip and restarting the driver on all active functions
of the chip where the parity error has been reported.

Moved the dmae_command from the heap to the stack. This will save 56
bytes per bnx2x structure. As a side benefit, we can also reduce the
time the dmae_mutex is held. This is because do we not need to hold
this mutex when setting up the dmae command. The memory where is dmae
command is stored is not a shared resource and doesn not need to be
protected.

When a given ring is running out of space, the FW can send pause towards the
network. When working with multi-queues, when one queue is getting out of space
it can block all other queues. The preferred scheme is to send pause frames only
when running out of the shared internal chip buffers and if a given queue cannot
place a packet on the host, it will drop it. Since some users might want to work
in drop-less mode, allowing changing the behavior as a module parameter.

The new FW improves the packets per second rate. It required a lot of change in
the FW which implies many changes in the driver to support it. It is now also
possible for the driver to use a separate MSI-X vector for Rx and Tx - this also
add some to the complicity of this change.
All things said - after this patch, practically all performance matrixes show
improvement.
Though Vladislav Zolotarov is not signed on this patch, he did most of the job
and deserves credit for that.

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.

>From now on FW will be downloaded from the binary file using request_firmware.
There will be different files for every supported chip. Currently 57710 (e1) and
57711 (e1h).
File names have the following format: bnx2x-<chip version>-<FW version>.fw.
ihex versions of current FW files are submitted in the next patch.
Each binary file has a header in the following format:
struct bnx2x_fw_file_section {
__be32 len;
__be32 offset;
}
struct bnx2x_fw_file_hdr {
struct bnx2x_fw_file_section init_ops;
struct bnx2x_fw_file_section init_ops_offsets;
struct bnx2x_fw_file_section init_data;
struct bnx2x_fw_file_section tsem_int_table_data;
struct bnx2x_fw_file_section tsem_pram_data;
struct bnx2x_fw_file_section usem_int_table_data;
struct bnx2x_fw_file_section usem_pram_data;
struct bnx2x_fw_file_section csem_int_table_data;
struct bnx2x_fw_file_section csem_pram_data;
struct bnx2x_fw_file_section xsem_int_table_data;
struct bnx2x_fw_file_section xsem_pram_data;
struct bnx2x_fw_file_section fw_version;
}
Each bnx2x_fw_file_section contains the length and the offset of the appropriate
section in the binary file. Values are stored in the big endian format.
Data types of arrays:
init_data __be32
init_ops_offsets __be16
XXsem_pram_data u8
XXsem_int_table_data u8
init_ops struct raw_op {
u8 op;
__be24 offset;
__be32 data;
}
fw_version u8
>From now boundaries of a specific initialization stage are stored in
init_ops_offsets array instead of being defined by separate macroes. The index
in init_ops_offsets is calculated by BLOCK_OPS_IDX macro:
#define BLOCK_OPS_IDX(block, stage, end) \
(2*(((block)*STAGE_IDX_MAX) + (stage)) + (end))
Security:
In addition to sanity check of array boundaries bnx2x will check a FW version.
Additional checks might be added in the future.
