Problem: iscsid crash seen while iscsid session recovery
Solution: During session recovery the driver sent multiple
ISCSI_CONN_STATE_LOGGED_IN event from qla4xxx_conn_start() and
qla4xxx_ddb_change(). Added fix to send only one
ISCSI_CONN_STATE_LOGGED_IN event.
Introduced: Day One
Impact: HW: ISP8032
OS: RHEL 6.2, RHEL 6.3, RHEL 6.4, SLES 11 SP2
Protocol: iSCSI
Defect/Enhancement: Defect
Problem: Memory corruption issue seen in qla4xxx_get_ep_fwdb
Solution: In qla4xxx_get_ep_fwdb(), dst_addr is of type struct sockaddr.
We are copying sizeof(struct sockaddr_in6) bytes to dst_addr
which is 12 bytes larger. This caused memory corruption.
So change dst_addr to struct sockaddr_storage which is
of 128 byte, large enough to hold sizeof(struct sockaddr_in6).

----------------------
Defect/Enhancement: Defect
Problem: Loopback test failure when initiated by iSCSI protocol [ER102082]
Solution: While the driver restores the original port configuration using
set_port_config, wait for IDC completion AEN and LINK UP event
before completing the loopback iteration and giving control to
application. This ensures that events of one loopback iteration
do not intervene the next iteration.
Introduced: Driver v5.03.01.08.xx.xx-x0
Impact: HW: ISP8032
OS: All supported Linux flavors
Protocol: iSCSI

Problem: IPv6 targets do not come back online after cable pulls (LINK DOWN/UP)
Solution: Set options field of ddb_entry struct to identify IPv6 target.
After driver DDB allocation, options field of ddb_entry struct
was not populated. So IPv6 targets behaved like IPv4 targets and
