Port speed printing was added by commit d948e6383e ("scsi: fnic: Add port
speed stat to fnic debug stats"). As currently configured, this will cause
the port speed to be printed to syslog every 2 seconds. To prevent log
spamming, only print the vnic port speed at driver initialization and if
the speed changes. Also clean up a small typo in fnic_trace.c.

Signed-off-by: Saurav Kashyap <skashyap@marvell.com>
Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
Problem Statement:
- Driver has fc_id of 0xcc0200
- Driver gets link down (due to test) and calls fcoe_ctlr_link_down().
- At this point, the fc_id of the initiator port is zeroed out.
- Driver gets a link up 14 seconds later.
- Driver performs FIP VLAN request, gets a response from the switch.
- No change in VLAN is detected.
- Driver then notifies libfcoe via fcoe_ctlr_link_up().
- Libfcoe then issues a multicast discovery solicitation as expected.
- Cisco FCF responds to that correctly.
- Libfcoe at this point starts a 3 sec count-down to allow any other FCFs
to be discovered. However, at this point, it has been 20 seconds since
the last FKA from the driver (which would have been sent prior to
backlink toggle), which causes the CVL to be issued from Cisco CVL from
the switch is dropped by the driver as the vx_port identification
descriptor is present and has value of 0xcc0200, which does not match
the driver's value of 0. Libfcoe completes the 3 sec count down and
proceeds to issue FLOGI as per protocol. Switch rejects FLogi request.
All subsequent FLOGI requests from libfc are rejected by the switch
(possibly because it is now expecting a new solicitation). This
situation will continue until the next link toggle.
Solution:
The Vx_port descriptor in the CVL has three fields:
MAC address
Fabric ID
Port Name
Today, the code checks for both #1 and #2 above. In the case where we went
through a link down, both these will be zero until FLOGI succeeds.
We should change our code to check if any one of these 3 is valid and if
so, handle the CVL (basically switching from AND to OR). The port name
field is definitely expected to be valid always.

This patch provides a module parameter and sysfs interface to select
whether the queue depth for each device should be based on the
protocol-specific value set by the driver (the default) or the maximum
supported by the controller (can_queue).
Although we have a sysfs interface per sdev to change the queue depth
of individual scsi devices, this implementation provides a single
sysfs entry per shost to switch between the controller max and the
driver default.

Currently bits in hba->outstanding_tasks are cleared only after their

If timeout happens in a task management command, its corresponding bit in
hba->outstanding_tasks will not be cleared until next task management
command with the same tag used successfully finishes.
This is wrong and can lead to some issues, like power issue. For example,
ufshcd_release() and ufshcd_gate_work() will do nothing if
hba->outstanding_tasks is not zero even if both UFS host and devices are
actually idle.
Solution is referred from error handling of device commands: bits in

Currently, each hardware queue, typically allocated per-cpu, consists of a
WQ/CQ pair per protocol. Meaning if both SCSI and NVMe are supported 2
WQ/CQ pairs will exist for the hardware queue. Separate queues are
unnecessary. The current implementation wastes memory backing the 2nd set
of queues, and the use of double the SLI-4 WQ/CQ's means less hardware
queues can be supported which means there may not always be enough to have
a pair per cpu. If there is only 1 pair per cpu, more cpu's may get their
own WQ/CQ.
Rework the implementation to use a single WQ/CQ pair by both protocols.

FC-NVMe-2 added support for sequence level error recovery in the FC-NVME
protocol. This allows for the detection of errors and lost frames and
immediate retransmission of data to avoid exchange termination, which
escalates into NVMeoFC connection and association failures. A significant
RAS improvement.
The driver is modified to indicate support for SLER in the NVMe PRLI is
issues and to check for support in the PRLI response. When both sides
support it, the driver will set a bit in the WQE to enable the recovery
behavior on the exchange. The adapter will take care of all detection and
retransmission.

Typical SLI-4 hardware supports up to 2 4KB pages to be registered per XRI
to contain the exchanges Scatter/Gather List. This caps the number of SGL
elements that can be in the SGL. There are not extensions to extend the
list out of the 2 pages.
The G7 hardware adds a SGE type that allows the SGL to be vectored to a
different scatter/gather list segment. And that segment can contain a SGE
to go to another segment and so on. The initial segment must still be
pre-registered for the XRI, but it can be a much smaller amount (256Bytes)
as it can now be dynamically grown. This much smaller allocation can
handle the SG list for most normal I/O, and the dynamic aspect allows it to
support many MB's if needed.
The implementation creates a pool which contains "segments" and which is
initially sized to hold the initial small segment per xri. If an I/O
requires additional segments, they are allocated from the pool. If the
pool has no more segments, the pool is grown based on what is now
needed. After the I/O completes, the additional segments are returned to
the pool for use by other I/Os. Once allocated, the additional segments are
not released under the assumption of "if needed once, it will be needed
again". Pools are kept on a per-hardware queue basis, which is typically
1:1 per cpu, but may be shared by multiple cpus.
The switch to the smaller initial allocation significantly reduces the
memory footprint of the driver (which only grows if large ios are
issued). Based on the several K of XRIs for the adapter, the 8KB->256B
reduction can conserve 32MBs or more.
It has been observed with per-cpu resource pools that allocating a resource
on CPU A, may be put back on CPU B. While the get routines are distributed
evenly, only a limited subset of CPUs may be handling the put routines.
This can put a strain on the lpfc_put_cmd_rsp_buf_per_cpu routine because
all the resources are being put on a limited subset of CPUs.
