This patch adds a shutdown routine. It fixes a bug where when be2net
and be2iscsi are both used be2iscsi was not cleaning up its resources
properly causing be2net to fail to get loaded when the system is
rebooted.

Fix be2iscsi driver to use a separate pointer for each irq action->name
field and avoid display corruption in /proc/interrupts. The be2iscsi driver
was using a single static array in a function for the irq action->name field.
This results in garbage output from /proc/interrupts
The pointer for action->name is garbage and scribbles the output on the screen.
This patch fixes the problem:

This patch is based on Prarit's patch here:

but I have fixed up the failure paths and removed
redundant check for !i suggested by Eike.

Since active_mask is first assigned in an "else" block, the compiler throws
a warning saying that the active_mask variable may be used uninitialized in
a print statement later. Initialize active_mask to 0 in the declaration to
stop the warning.

The iscsi_nopout task's TTT is defined as __be32 while the DMA
memory to the chip is CPU specific. This creates a problem for
unsolicited NOP-In responses where the TTT is not the RESERVED
tag of 0xFFs. This patch adds a call to be32_to_cpu for the TTT
specified.

In commit 6a716a8, while releasing the DDP context in case frame_send() failed,
the frame may already be freed, so we should store the pointer to fc_fcp_pkt and
release the DDP context using the locally stored fsp instead of getting fsp from
the fr_fsp(fp) on a frame.

Current fc_eh_host_reset leaves lport offline
permanently due to FLOGI response getting
handled by LOGO response from last reset as both
had same exchange id.
So fix this by having end to end exches clean-up
using exchange abort along exches reset
done from fc_eh_host_reset. This would avoid
exchanges collision between the sessions across
the reset. In this case implicit login should have
done that but no aborting support for FIP
frames, so just wait till lport->r_a_tov before
restarting next flogi to ensure all exchanges
are good to use again for next session.
Below is the trace of LOGO from older session
coming ahead of FLOGI response with same exche id

The rtnl cannot be held durrng the fcoe_interface_put.
If it is the last reference on the fcoe_interface the
fcoe_ctlr_destroy will be called as a part of the
cleanup, ultimately calling cancel_work_sync(&fip->recv_work);
If we are processing a flogi response we will be in
the recv_work context and we will lock the rtnl to
add a new unicast MAC address. This is how the deadlock
can occur.
The fix is simply to move the rtnl_lock/unlock into
fcoe_interface_cleanup so that it can be unlocked before
fcoe_interface_put is called.
Here is the lockdep report:

The Marvell Universal Message Interface (UMI) defines a messaging
interface between host and Marvell products (Plato, for example). It
considers situations of limited system resource and optimized system
performance.
UMI driver translates host request to message and sends message
to FW via UMI, FW receives message and processes it, then sends response
to UMI driver.
FW generates an interrupt when it needs to send information or
response to UMI driver

Some CD-ROMs fail to report a media change correctly. The specific
one for this patch simply fails to respond to commands, then gives a
UNIT ATTENTION after being reset which returns ASC/ASCQ 28/00. This
is out of spec behaviour, but add a check in the eat CC/UA on reset
path to catch this case so the CD-ROM will function somewhat properly.

1. Remove device database entry (ddb) state.
2. Remove device database (DDB) list building.
With open-iscsi integration the logins to the target devices are
handled by the user space. So the information of target is now
maintained in the iscsi_session object. This is handled at
libiscsi level so there is no need to maintain a list of DDBs in
the qla4xxx LLD.
3. qla4xxx: Remove add_device_dynamically.
Since autologin in FW is disabled with open-iscsi integration,
driver will never get an AEN for which driver has not requested
a DDB index. So remove the add_device_dynamically function.
4. Remove qla4xxx_tgt_dscvr
Since firmware autologin is disabled this function will not work.
Now user has the ability to do the target discovery and login to
each target individually. Firwmare will not do the login on its own.
5. Remove relogin related code
All relogin is handled by userspace now. qla4xxx just need to
notify userspace of a connection failure, this triggers the
relogin.
6. Remove add_session and alloc_session
Now qla4xxx uses iscsi_session_setup that would do the necessary
allocations for session and ddb_entry.

Add scsi_transport_iscsi hooks in qla4xxx to support
iSCSI session management using iscsiadm.
This patch is based on discussion here
http://groups.google.com/group/open-iscsi/browse_thread/thread/e89fd888baf656a0#
Now users can use iscsiadm to do target discovery and do login/logout to
individual targets using the qla4xxx iSCSI class interface.
This patch leaves some dead code, but to make it easier to review
we are leaving and in the next patch we will remove that old code.
V2 - NOTE: Added code to avoid waiting for AEN during login/logout
in the driver, instead added a kernel to user event
to notify iscsid about login status. Because of this
iscsid will not get blocked.

support offload session login.
Offload drivers like qla4xxx will offload the sending of the login/logout
pdus still, so this patch adds iscsi_conn_login_event which is
used by these types of drivers to notify userspace that the connection
has changed state.
It also adds a iscsi_is_session_online helper so the lld
can query the sessions state field.
