Removed the individual PCI DEVICE ID checking inside bnx2i. The device
type can easily be read from the corresponding cnic->flags. This will
free bnx2i from having to get updated for every new device ID that gets
added.Signed-off-by: Eddie Wai

The netdev->base_addr parameter has been deprecated in the L2 bnx2
driver. This is used by bnx2i for the BARn iomapping.This patch will directly reference the pci_resource_start instead
of using the deprecated netdev->base_addr.This patch is actually a critical bug fix as the 1G bnx2 driver no
longer supports the netdev->base_addr in the current kernel of the scsi
tree. This means that Broadcom's 1G Linux iSCSI offload solution would
not work at all without this patch.Signed-off-by: Eddie Wai

The iscsi class currently does not support writable sysfs
attrs for LLD sysfs settings. This patch converts the
iscsi class and driver's host attrs to use the attribute
container sysfs group and the sysfs group's is_visible callout
to be able to support readable or writable sysfs attrs.Signed-off-by: Mike Christie

Bumped version from 2.6.2.3 to 2.7.0.3

This patch breaks the SCSI cmd completion into two parts:
1. The bh will allocate and queued work to the cmd specific CPU IO
completion kthread. The CPU for the cmd is from the sc->request->cpu.2. The CPU specific IO completion kthread will call the scsi_cmd_resp
routine to do the actual cmd completion.In the normal case, these IO completion kthreads should complete before
the blk IO times out at 60s. However, in the case when these kthreads
are blocked for whatever reason and exceeded the timeout, the call
to conn_destroy will have to iterate and exhaust all related work in the
percpu work list for all online CPUs. This will guarantee the protection
of the work->session and conn pointers before they get freed.Also modified the event coalescing formula to have at least the
event_coal_min outstanding cmds in the pipeline so the SCSI producer
would not get underrun.Also changed the following SCSI parameters:
- can_queue from 1024 to 2048
- cmds_per_lun from 24 to 128Signed-off-by: Eddie Wai

Modified the event coalescing code for iSCSI offload to combat both
corner cases and optimize performance as follows:1. Added mechanism to loop back a second time to process any leftover
CQEs that was generated by the hardware during the time the driver is
busy processing previous CQEs in the bh. This not only helps the
performance but also fixes the corner case when no more CQEs are being
generated in the pipeline; so those leftover CQEs will get a a chance
to be processed.2. Added ARM_CQE_FP to distinguish between fast path arming versus
slow path arming. This change will guarantee that the CQEs will
always get a chance to be re-armed during fast path completions.3. Removed the inline event coalescing division for perf optimization.
Also fixed a division-by-zero error when the event_coal_div module
param was set to 0.4. Changed the default SQ WQEs size from 256 to 128 to match chip
default.5. Changed the cmd_per_lun from 32 to 24.

The number of chip's internal command cell, which is use to generate
SCSI cmd packets to the target, was not initialized correctly by
the driver when the sq_size is changed from the default 128.
This, in turn, will create a problem where the chip's transmit pipe
will erroneously reuse an old command cell that is no longer valid.
The fix is to correctly initialize the chip's command cell upon setup.Signed-off-by: Eddie Wai
