Add trunking support to the driver. Trunking is found on more recent
asics. In general, trunking appears as a single "port" to the driver
and overall behavior doesn't differ. Link speed is reported as an
aggregate value, while link speed control is done on a per-physical
link basis with all links in the trunk symmetrical. Some commands
returning port information are updated to additionally provide
trunking information. And new ACQEs are generated to report physical
link events relative to the trunk.
This patch contains the following modifications:
- Added link speed settings of 128GB and 256GB.
- Added handling of trunk-related ACQEs, mainly logging and trapping
of physical link statuses.
- Added additional bsg interface to query trunk state by applications.
- Augment link_state sysfs attribtute to display trunk link status

Testing a point-to-point topology and a case of re-FLOGI without
intervening link bouncing, showed an odd interaction with firmware and
a resulting scenario where the driver no longer probed after accepting
the new FLOGI.
Work around the firmware issue by issuing a link bounce if a FLOGI is
received after the link is already up and FLOGI's accepted.
While debugging the issue, realized that some debug traces should be

resolution in this situation is to retry a couple of times, then drop

After a LOGO in response to an ABTS timeout, a PLOGI wasn't issued to
re-establish the login. An nlp_type check in the LOGO completion
handler failed to restart discovery for NVME targets. Revised the
nlp_type check for NVME as well as SCSI.
While reviewing the LOGO handling a few other issues were seen and
were addressed:
- Better lock synchronization around ndlp data types
- When the ABTS times out, unregister the RPI before sending the LOGO
so that all local exchange contexts are cleared and nothing received
while awaiting LOGO/PLOGI handling will be accepted.
- LOGO handling optimized to:
Wait only R_A_TOV for a response.
It doesn't need to be retried on timeout. If there wasn't a
response, a PLOGI will be sent, thus an implicit logout
applies as well when the other port sees it.
If there is a response, any kind of response is considered "good"
and the XRI quarantined for a exchange qualifier window.
- PLOGI is issued as soon a LOGO state is resolved.

Currently driver checks for Firmware state change from ISR context, and
only when there are interrupts tied with no I/O completions. We have seen
multiple cases where doorbell interrupts sent by firmware to indicate FW
state change are not processed by driver and it takes long time for driver
to trigger OCR. And if there are no IOs running, since we only check the FW
state as part of ISR code, fault goes undetected by driver and OCR will not
be triggered.
This patch introduces a separate workqueue that runs every one second to
detect Firmware FAULT state and trigger reset immediately. As an
additional gain, removing PCI reads from ISR to check FW state results in
improved performance as well.
