bb6a8a2c24 scsi: lpfc: Fix oops when NVME Target is discovered in a nonNVME environment
lpfc oops when it discovers a NVME target but is configured for SCSI
only operation. Oops is in lpfc_nvme_register_port+0x33/0x300.

The localport is not valid so it should not have been referenced.

Added validity check for localport

d2aa48761e scsi: lpfc: Fix rediscovery on switch blade pull
When the switch blade is pulled out then plugged back in, the driver
does not issue a PLOGI to the target

When the switch blade is pulled out, it does not reset the link. The
driver ends up issuing a LOGO to the target, and finally sees devloss.
Since the driver believes that a LOGO is outstanding, it does not issue
a PLOGI to the target upon link up

Correct by placing the ndlp in UNUSED state When devloss happens in
LOGO_ISSUE state.

2877cbffb7 scsi: lpfc: Fix loop mode target discovery
The driver does not discover targets when in loop mode.

The NLP type is correctly getting set when a fabric connection is
detected but, not for loop. The unknown NLP type means that the driver
does not issue a PRLI when in loop topology. Thus target discovery
fails.

Fix by checking the topology during discovery.  If it is loop, set the
NLP FC4 type to FCP.

1fe68477d2 scsi: lpfc: Fix plogi collision that causes illegal state transition
Message "0271 Illegal State Transition: node" seen in logs, all luns are
unuseable for that target.

A window exists in the rcv_plogi path where if the state is plogi issue
but the driver has not issued a plogi, then two reglogins will be sent
for the same RPI. The first one to complete will advance the state to
prli issue the second one will be detected as an illegal state, and
leave the node in an unusable state.

Correct the completion routine for the PLOGI ACC that detects the state
change when the driver starts discovery on the node again and drop the
REGLOGIN mailbox command.

d61cca60aa scsi: qla2xxx: Do not call abort handler function during chip reset
If there are IO's running and host reset or chip reset is triggered,
IO's can fail due to rport time out. During chip reset recovery process,
driver notifies the transport layer that remote port no longer exist, by
calling fc_remote_port_delete(). When this function is called, it
actually delays deletion by "blocking" it. It sets the remote port state
to "FC_PORTSTATE_BLOCKED" and sets FC_RPORT_DEVLOSS_PENDING.  When
driver tries to abort the command by calling its abort handler function,
abort handler will wait until remote port state is blocked state or wait
for dev_loss_tmo time. Due to this blocking, rport times out and results
in an IO failure. This patch adds a check for any active reset process
before calling abort handler function.
