Added the handling for cases when a chip request is made to the
CNIC module but the hardware is not ready to accept. This would
lead to many unnecessary wait timeouts.
This code adds check in the connect establishment and destruction
path.

The code no longer needs to dynamically register and unregister
the CNIC device. The CNIC device will be kept registered until
module unload.

This is the new FW HSI blob and the relevant definitions without logic changes.
It also included code adaptation for new HSI. New features are not enabled.
New FW/HSI includes:
- Support for 57712 HW
- Future support for VF (not used)
- Improvements in FW interrupts scheme
- FW FCoE hooks (stubs for future usage)

In compliance to RFC793, a TCP graceful termination will be used
instead of an abortive termination for the case where the remote
has initiated the close of the connection.
Additionally, a TCP abortive termination will be used to close the
connection when a logout response is not received in time after a
logout request has been initiated.

Added variables to separate the fine tuned timeout values for
connection destroy and context destroy for both 1g and 10g devices.
v2: Extended the 5771X disconnect timeout from 10s to 20s as the firmware
has a retransmission timeout of 16s. This fixes one of the iscsi_endpoint
leak issues when the target is slow or non-responsive to our TCP FIN.

For cases where the iSCSI disconnection procedure times out due to
the iSCSI daemon being slow or unresponsive, the bnx2i_stop routine
will now perform hardware cleanup via bnx2i_hw_ep_disconnect on all
active endpoints so that subsequent operations will perform properly.
Also moved the mutex locks inside ep_connect and ep_disconnect so
that proper exclusivity can resolve simultaneous calls to the
ep_disconnect routine.
v2: Removed the unnecessary read lock in the bnx2i_stop

iscsi sessions
bnx2i driver has to wait and cleanup all iscsi endpoints before
returning from bnx2i_stop(). This is to make sure all chip resources
are freed before chip is reset.
As the requirements for 1G and 10G chipsets is different, added
per-device 'hba_shutdown_tmo' parameter to adapter structure
If the connections are not torn down by the daemon within this timeout
period, 'cid's will be leaked in 10G device. 1G devices are more
flexible and do not leak any resources because the whole chip ports
gets reset when MTU is changed or ethtool selftest is run
fixed a minor issue in bnx2i_ep_poll() which unnecessarily forced
error return code when driver timed out waiting for TCP connect
request to complete

This just has bnx2i use the iscsi_suspend_queue helper.
The suspend works as follows:
When ep_poll has succeeed iscsid will call conn_bind, the LLD will
then call iscsi_conn_bind which will clear the suspend bit.
When ep_disconnect is called (or if there is a conn error) we set
the suspend bit. For the ep_disconnect case I added a helper
in the previous kernel that will take the session lock to make sure
iscsi_queuecommand/xmit_task is not running and it will set
the suspend bit.

5706/5708/5709 devices allow driver/user to set page size. By default it is
set to 4096. Current drivers do not program this register based on
architecture type (e.g. x86 = 4K, IA64 = 16K) and by choice lets device use
the defaults. So while mapping connection context memory (doorebll registers),
driver has to match page size used by the device. Included change fixes the
issue we uncovered during IA64 testing
