QLogic applications store the CHAP information in FLASH. During login,
authentication information is provided using an index into the CHAP region.
In order to support QLogic applications along with iscsiadm, updated the
LLD to not add duplicate CHAP entries in the CHAP region and preserve the
existing CHAP info in the CHAP region in FLASH.
This allows QLogic applications to pre-write the CHAP entries in the
CHAP region.
With iscsiadm, when the CHAP authentication information is sent to the LLD, the
LLD searches for the entry in CHAP region in FLASH, if exists then do not add.
If CHAP entry does not exist then add the CHAP entry in the CHAP region.

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.

FW is not able to process mbox command if FW state is failed. This will cause
mbox command to timeout and adapter reset. We have separate function to detect
FW failed state and do adapter reset. So to avoid mbox command timeout, do not

Outstanding mailbox commands, have no way to recover on f/w hung, and we
timeout on waiting for mbx response. This in turn affects the recovery process
as follows:
- We might already be in dpc while waiting for mbx to complete, so recovery for
that pci function will never get invoked. Reset Timeout (10 sec) is far less
than mbx timeout (30 sec).
- Other mbx cmds will get stuck due to serial mbx access.
Solution is to identify fw-hung scenario and handle outstanding mbx commands to
have an early-exit instead of waiting for response.
Other mbx commands waiting for access will also do an early-exit if fw-hung is
still applicable.

The included patch fixes the following issues:
1. qla3xxx/qla4xxx co-existence issue which can result in a lockup
when qla3xxx driver is unloaded, or when ifdown; ifup is performed on
one of the interfaces correponding to qla3xxx. This is because qla4xxx
HBA supports one ethernet and iscsi interfaces per port. Both iscsi
and ethernet interfaces share the same state machine. The problem has
to do with synchronizing access to the state machine in the event of a
reset
2. mutex_lock() is sometimes not followed by mutex_unlock() prior to
invoking a msleep() in qla4xxx_mailbox_command()
