Udev uses the connection's persistent address/port in the
/dev/disk/by-path name. qla4xxx is not exporting this value
so its iscsi disk names have been lacking the iscsi info.
In the old driver we did not have this information but
we do now and can fix this by just setting the flags to tell
libiscsi/scsi_transport_iscsi to export this info in sysfs.Signed-off-by: Mike Christie

Userspace was sending the priority/id part of the vlan tag
and sysfs was displaying the id in the vlan file. This
renames the vlan sysfs file to vlan_id to reflect that it
was showing the id and to match the vlan_priority file.
This also adds a ISCSI_NET_PARAM_VLAN_TAG iscsi nl command
to relfect that we are sending down the vlan/priority
part of the tag.Signed-off-by: Mike Christie

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.JIRA Key: UPSISCSI-146

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.Signed-off-by: Manish Rangankar

Add scsi_transport_iscsi hooks in qla4xxx to support

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.Signed-off-by: Manish Rangankar
