Our code will ensure that hns3_clear_tx_ring is not used to cleared
RX rings and hns3_clear_rx_ring is not used to cleared TX rings. So
the ring type check is unnecessary.

RX Buffer Descriptor contains a VALID bit which indicates if the BD
is valid and has some data. This field is set by HNS3 hardware to
intimate the driver of some valid data present in the BD. nd should
be reset by the driver when BD is being used again. In the existing
code this bit was not being (re-)initialized properly and hence was
causing problems.

Before the firmware updates the crq's tail pointer, if the PF driver

which will lead to the driver read an unknown message.
This patch fixes it by checking if crq is not empty before reading the

In the latest revision of the hardware, if a packet is spanning
across multiple BDs then only VLD bit and current data size info
is valid in each BD, and rest of the information is only valid
in the last BD of the packet. In such case we should make sure
we are fetching RX packet size from the first descriptor and

SIMCOM are reusing a single device ID for many (all of their?)
different modems, based on different chipsets and firmwares. Newer
Qualcomm chipset generations require setting DTR to wake the QMI
function. The SIM7600E modem is using such a chipset, making it
fail to work with this driver despite the device ID match.
Fix by unconditionally enabling the SET_DTR quirk for all SIMCOM
modems using this specific device ID. This is similar to what
we already have done for another case of device IDs recycled over
multiple chipset generations: 14cf4a771b30 ("drivers: net: usb:
qmi_wwan: add QMI_QUIRK_SET_DTR for Telit PID 0x1201")

The netsec network controller IP can drive 64 address bits for DMA, and
the DMA mask is set accordingly in the driver. However, the SynQuacer
SoC, which is the only silicon incorporating this IP at the moment,
integrates this IP in a manner that leaves address bits [63:40]
unconnected.
Up until now, this has not resulted in any problems, given that the DDR
controller doesn't decode those bits to begin with. However, recent
firmware updates for platforms incorporating this SoC allow the IOMMU
to be enabled, which does decode address bits [47:40], and allocates
top down from the IOVA space, producing DMA addresses that have bits
set that have been left unconnected.
Both the DT and ACPI (IORT) descriptions of the platform take this into
account, and only describe a DMA address space of 40 bits (using either
dma-ranges DT properties, or DMA address limits in IORT named component
nodes). However, even though our IOMMU and bus layers may take such
limitations into account by setting a narrower DMA mask when creating
the platform device, the netsec probe() entrypoint follows the common
practice of setting the DMA mask uncondionally, according to the
capabilities of the IP block itself rather than to its integration into
the chip.
It is currently unclear what the correct fix is here. We could hack around
it by only setting the DMA mask if it deviates from its default value of
DMA_BIT_MASK(32). However, this makes it impossible for the bus layer to
use DMA_BIT_MASK(32) as the bus limit, and so it appears that a more
comprehensive approach is required to take DMA limits imposed by the
SoC as a whole into account.
In the mean time, let's limit the DMA mask to 40 bits. Given that there
is currently only one SoC that incorporates this IP, this is a reasonable
approach that can be backported to -stable and buys us some time to come
up with a proper fix going forward.

This patch enables virtio_net to switch over to a VF datapath when STANDBY
feature is enabled and a VF netdev is present with the same MAC address.
It allows live migration of a VM with a direct attached VF without the need
to setup a bond/team between a VF and virtio net device in the guest.
It uses the API that is exported by the net_failover driver to create and
and destroy a master failover netdev. When STANDBY feature is enabled, an
additional netdev(failover netdev) is created that acts as a master device
and tracks the state of the 2 lower netdevs. The original virtio_net netdev
is marked as 'standby' netdev and a passthru device with the same MAC is
registered as 'primary' netdev.
The hypervisor needs to unplug the VF device from the guest on the source
host and reset the MAC filter of the VF to initiate failover of datapath
to virtio before starting the migration. After the migration is completed,
the destination hypervisor sets the MAC filter on the VF and plugs it back
to the guest to switch over to VF datapath.
This patch is based on the discussion initiated by Jesse on this thread.

The net_failover driver provides an automated failover mechanism via APIs
to create and destroy a failover master netdev and manages a primary and
standby slave netdevs that get registered via the generic failover
infrastructure.
The failover netdev acts a master device and controls 2 slave devices. The
original paravirtual interface gets registered as 'standby' slave netdev and
a passthru/vf device with the same MAC gets registered as 'primary' slave
netdev. Both 'standby' and 'failover' netdevs are associated with the same
'pci' device. The user accesses the network interface via 'failover' netdev.
The 'failover' netdev chooses 'primary' netdev as default for transmits when
it is available with link up and running.
This can be used by paravirtual drivers to enable an alternate low latency
datapath. It also enables hypervisor controlled live migration of a VM with
direct attached VF by failing over to the paravirtual datapath when the VF
is unplugged.

The driver exits port setup after failing the lpfc_sli4_get_parameters

The older CNA adapters do not support the MBX command. In the past
the code was allowed to fail and continue on with initialization.
However a nvme change moved a closing bracket and now makes all
failures terminal.
Revise the logic so that terminal failure only occurs if the command
failed on the newer adapters. Additionally, if parameters are set
that require information from the command and the command failed,
the parameters are erroneous and port set up should fail even on

outstanding ios for an adapter. This value, by default, is set to 65536,
which exceeds the maximum exchange counts supported on an adapter. The ndlp

PHY of a port.
This is not an problem before, as we don't need to setup STP link from

In order to terminate STP reject quickly, this patch send ATA reset command

Besides, we do abort dev for each device before terminating STP reject.

We may reset the controller in many scenarios, such as SCSI EH and HW
errors. There should be no IO which returns from target when SCSI EH is
active. But for other scenarios, there may be. It is not necessary to make
such IOs fail.
This patch adds an function of trying to wait for any commands, or IO, to
complete before host reset. If no more CQ returned from host controller in
100ms, we assume no more IO can return, and then stop waiting. We wait 5s
at most.
The HW has a register CQE_SEND_CNT to indicate the total number of CQs that
has been reported to driver. We can use this register and it is reliable to
resd this register in such scenarios that require host reset.

After the controller is reset, it is possible that the disks attached still
have outstanding IO to complete.
Thus, when the PHYs come back up after controller reset, it is possible
that these IOs complete at some unknown point later.
We want to ensure that all IOs are complete after the controller reset so
that all associated IPTT and other resources can be recycled safely.
To achieve this, re-init the disks by TMF or softreset (in case of ATA
devices).
If the init fails - maybe because the device was removed or link has not
come up - then do not release the device resources, but rather rely on SCSI
EH to handle the timeout for these resources later on.
This patch also does some cleanup to hisi_sas_init_disk(), including
removing superfluous cases in the switch statement.

When a SCSI host is registered, the SCSI mid-layer takes a reference to a
module in Scsi_host.hostt.module. In doing this, we are prevented from
removing the driver module for the host in dangerous scenario, like when a
disk is mounted.
Currently there is only one scsi_host_template (sht) for all HW versions,
and this is the main.c module. So this means that we can possibly remove
the HW module in this dangerous scenario, as SCSI mid-layer is only
referencing the main.c module.
To fix this, create a sht per module, referencing that same module to
create the Scsi host.

There is much common code and functionality between the HW versions to set
the PHY linkrate.
As such, this patch factors out the common code into a generic function
hisi_sas_phy_set_linkrate().

Trivial fix to spelling mistake in pm8001_printk message text; also I
believe NOT_UNSUPPORTED should probably be NOT_SUPPORTED. Also fix the
indent of the pm8001_printk statement.

Commit 505aa4b6a883 ("scsi: sd: Defer spinning up drive while SANITIZE is
in progress") may not be sufficient, especially if the SCSI SANITIZE
command is sent via the bsg or sg pass-throughs, since they don't use the
sd driver.
Add "Sanitize in progress" plus some other recent "... in progress"
additional sense codes into the scsi mid-level so they are treated in a
similar fashion to "Format in progress".

Since an SRP remote port is attached as a child to shost->shost_gendev
and as the only child, the translation from the shost pointer into an
rport pointer must happen by looking up the shost child that is an
rport. This patch fixes the following KASAN complaint:

CineS2 V7(A) and Octopus CI S2 Pro/Advanced cards support faster TS speeds
on the card's contained stv0910 demodulator when their FPGA was updated
with a recent (>= 1.7, version number applies to all mentioned cards)
vendor firmware. Enable this faster TS speed on card port 0 (contained
demod) and parallel stv0910 connections when the card firmware is at least
1.7 or later.
Note: The mentioned cards and their demods are handled via the STV0910_PR
and STV0910_P tuner types. DuoFlex modules with such demodulators are
handled via the STV0910 (without suffix) types where such TS speed
increase doesn't technically make sense.

Add a tsspeed config option to struct stv0910_cfg which can be used by
users of the driver to set the (parallel) TS speed (higher speeds enable
support for higher bitrate transponders). If tsspeed isn't set in the
config, it'll default to a sane value.
This commit also updates the two consumers of the stv0910 driver (ngene
and ddbridge) to have a default tsspeed in their stv0910_cfg templates.
