This feature is to override the default
max_sectors setting at load time, taking max_sectors as an
command line option when loading the driver. The setting is
currently hard-coded in the driver to 8192 sectors (4MB transfers).
If max_sectors is specified at load time, minimum specified
setting will be 64, and the maximum is 8192. The driver will
modify the setting to be on even boundary. If max_sectors is not
specified, the driver will default to 8192.

This memcpy:
memcpy(cmd->sense_buffer, ei->SenseInfo,
ei->SenseLen > SCSI_SENSE_BUFFERSIZE ?
SCSI_SENSE_BUFFERSIZE :
ei->SenseLen);
The ei->SenseLen field is filled in by the Smart Array. For requests to
logical drives, it will not exceed 32 bytes, so should be ok, but for physical
requests it depends on the target device, not the Smart Array. It's conceivable
that this could exceed the 32 byte size of ei->SenseInfo. In that case, the memcpy
would read past the end of ei->SenseInfo, copying data from the next command,
as if it were sense data, or, if it happened to be the very last command in the
block of allocated commands, could fall off the end of the allocated area and
crash. I'm not aware of anyone ever encountering this behavior, but it could
conceivably happen. This bug was found by Coverity.

Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone
as the physical port and shares the same LUN. This happens due to the fact that
vport destroy and unsolicited ELS are scheduled to run on the same workqueue,
and vport destroy destroys the lport and the unsolicited ELS tries to access
the invalid lport. This patch fixes this issue by maintaining a list of valid
lports and verifying if the lport is valid or not before accessing it.

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.

In certain circumstances, we can get an oops from a torn down device.
Most notably this is from CD roms trying to call scsi_ioctl. The root
cause of the problem is the fact that after scsi_remove_device() has
been called, the queue is fully torn down. This is actually wrong
since the queue can be used until the sdev release function is called.
Therefore, we add an extra reference to the queue which is released in
sdev->release, so the queue always exists.

- Reorganize CQ and EQ usage to comply with SLI4 Specification.
- Expand the driver to check the rn bit. Only detect an error if the error bit
is set and the RN bit is NOT set.
- If mailbox completion code is not success AND the mailbox status is success,
then and only then will the driver overwrite the mailbox status.
- When driver initializing device, if the device is on a PCIe bus, set
PCI's "needs fundamental reset" bit so that EEH uses fundamental reset
instead of hot reset for recovery.
- Prevent driver from using new WWN when changed in firmware (until driver
reload)
- When HBA reports maximum SGE size > 0xffffffff (infinite), override

- Fixed potential missed SLI4 device initialization failure conditions.
- Added 100ms delay before driver action following IF_TYPE_2 function reset.
- Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node.
- Add a check for the CVL received flag in the fcf inuse routine to avoid
