For 4032, context reset was the same as chip reset, and any firmware
issue was recovered by performing a chip reset.
For 82xx, the iSCSI firmware runs along with FCoE and the NIC
firmware contexts, and an error encountered doesnot essentially mean
that a chip reset is necessary.Perform Chip resets only in the following cases:
1. Mailbox system error.
2. Mailbox command timeout.
3. fw_heartbeat_counter counter stops incrementing.For all other cases, only perform a context reset.
1. Command Completion with an invalid srb.
2. Other mailbox failures.Signed-off-by: Vikas Chaudhary

iscsi_conn_setup can fail so we must check for NULL being
returned.Signed-off-by: Mike Christie
Signed-off-by: James Bottomley -
When the qla4xxx_get_fwddb_entry returns QLA_ERROR
the nex_idx is not updated,
for (idx = 0; idx < max_ddbs; idx = next_idx) {
ret = qla4xxx_get_fwddb_entry(ha, idx, NULL, 0, NULL,
&next_idx, &state, &conn_err,
NULL, NULL);
if (ret == QLA_ERROR)
continue;This means there is a risk that the 'idx < max_ddbs' condition will never
met and the loop will loop forever.
Fix this by explicitly increasing the next_idx in the error condition.Maybe a break instead of continue is more appropriate, leaving the decision
on the qlogic maintainer.Signed-off-by: Tomas Henzl

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

Firmware reserves DDBs if there are entries in the FLASH.
So there are no free DDBs left when a iSCSI login is initiated
by user space tool like iscsiadm.
Since now login is not controlled by firmware, LLD need to free
up the DDBs after firmware init. This will ensure free DDBs are
available for iSCSI logins using iscsiadm.JIRA Key: UPSISCSI-151

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
