Currently we use a mixture of %016llx, %llx, and %16llx when printing a SAS
address.

Since the most significant nibble of the SAS address is always 5 - as per
standard - this formatting is not so important; but some fake SAS addresses
for SATA devices may not be. And we have mangled/invalid address to
consider also. And it's better to be consistent in the code, so use a fixed
format.

The SAS address is a fixed size at 64b, so we want to 0 byte extend to 16
nibbles, so use %016llx globally.

Also make some prints to be explicitly hex, and tidy some whitespace issue.

When running Cisco-MDS diagnostics which perform driver-level frame loop
back, the switch is reporting errors. Diagnostic has a limit on latency
that is not being met by the driver.

The requirement of Latency frames is that they should be responded back by
the host with a maximum delay of few hundreds of microseconds. If the
switch doesn't get response frames within this time frame, it fails the
test.

Test is failing as the lpfc-wq workqueue was overwhelmed by the packet rate
and in some cases, the work element yielded to other kernel elements.

To resolve, reduce the outstanding load allowed by the adapter. This
ensures the driver spends a reasonable amount of time doing loopback and
can do so such that latency values can be met.  Load is managed by reducing
the number of receive buffers posted such that the link can be
backpressured to reduce load.

There are reports of multiple ports on the same system displaying different
hostnames in fabric FDMI displays.

Currently, the driver registers the hostname at initialization and obtains
the hostname via init_utsname()->nodename queried at the time the FC link
comes up. Unfortunately, if the machine hostname is updated after
initialization, such as via DHCP or admin command, the value registered
initially will be incorrect.

Fix by having the driver save the hostname that was registered with FDMI.
The driver then runs a heartbeat action that will check the hostname.  If
the name changes, reregister the FMDI data.

The hostname is used in RSNN_NN, FDMI RPA and FDMI RHBA.

NVMe device re-discovery does not complete. Dev_loss_tmo messages seen on
initiator after recovery from a link disturbance.

The failing case is the following:

When the driver (as a NVME target) receives a PLOGI, the driver initiates
an "unreg rpi" mailbox command. While the mailbox command is in progress,
the driver requests that an ACC be sent to the initiator. The target's ACC
is received by the initiator and the initiator then transmits a PLOGI. The
driver receives the PLOGI prior to receiving the completion for the PLOGI
response WQE that sent the ACC. (Different delivery sources from the hw so
the race is very possible). Given the PLOGI is prior to the ACC completion
(signifying PLOGI exchange complete), the driver LS_RJT's the PRLI. The
"unreg rpi" mailbox then completes. Since PRLI has been received, the
driver transmits a PLOGI to restart discovery, which the initiator then
ACC's.  If the driver processes the (re)PLOGI ACC prior to the completing
the handling for the earlier ACC it sent the intiators original PLOGI,
there is no state change for completion of the (re)PLOGI. The ndlp remains
in "PLOGI Sent" and the initiator continues sending PRLI's which are
rejected by the target until timeout or retry is reached.

Fix by: When in target mode, defer sending an ACC for the received PLOGI
until unreg RPI completes.
