In Striding RQ, each WQE serves multiple packets
(hence called Multi-Packet WQE, MPWQE).
The size of a MPWQE is constant (currently 256KB).
Upon a ringparam set operation, we calculate the number of
MPWQEs per RQ. For this, first it is needed to determine the
number of packets that can reside within a single MPWQE.
In this patch we use the actual MTU size instead of ETH_DATA_LEN
for this calculation.
This implies that a change in MTU might require a change
in Striding RQ ring size.
In addition, this obsoletes some WQEs-to-packets translation
functions and helps delete ~60 LOC.

Knowing the MTU is required for RQ creation flow.
By our design, channels creation flow is totally isolated
from priv/netdev, and can be completed with access to
channels params and mdev.
Adding the MTU to the channels params helps preserving that.
In addition, we save it in RQ to make its access faster in
datapath checks.

Commit eed85ff4c0da ("PCI/DPC: Enable DPC only if AER is available") made
DPC control dependent whether AER is enabled in the OS. However, it does
not take into account situations where BIOS has not given OS control of
AER:
acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM Segments MSI]
acpi PNP0A08:00: _OSC: platform does not support [AER]
acpi PNP0A08:00: _OSC: OS now controls [PCIeHotplug PME PCIeCapability]
I think here it is better not to enable DPC even if the capability is
available because then it would be against what "Determination of DPC
Control" note in PCIe 4.0 sec 6.1.10 recommends.

The primary interface for the touchpad device in Thinkpad L570 is SMBus,
so ALPS overlooked PS2 interface Firmware setting of TrackStick, and
shipped with TrackStick otp bit is disabled.
The address 0xD7 contains device number information, so we can identify
the device by checking this value, but to access it we need to enable
Command mode, and then re-enable the device. Devices shipped in Thinkpad
L570 report either 0x0C or 0x1D as device numbers, if we see them we assume
that the devices are DualPoints.
The same issue exists on Dell Latitude 7370.

The platform may restrict the OS's use of PCIe services, e.g., via the ACPI
_OSC method. The user may use "pcie_ports=native" to force the port driver
to use PCIe services even if the platform asked us not to.
The "pcie_ports=native" parameter determines the setting of
pcie_ports_auto. Rename this to pcie_ports_native and reverse the
sense to simplify the code.

7570a333d8b0 ("PCI: Add pcie_hp=nomsi to disable MSI/MSI-X for pciehp
driver") added the "pcie_hp=nomsi" kernel parameter to work around this
error on shutdown:
irq 16: nobody cared (try booting with the "irqpoll" option)
Pid: 1081, comm: reboot Not tainted 3.2.0 #1
...
Disabling IRQ #16
This happened on an unspecified system (possibly involving the Integrated
Device Technology, Inc. Device 807f bridge) where "an un-wanted interrupt
is generated when PCI driver switches from MSI/MSI-X to INTx while shutting
down the device."
The implication was that the device was buggy, but it is normal for a
device to use INTx after MSI/MSI-X have been disabled. The only problem
was that the driver was still attached and it wasn't prepared for INTx
interrupts. Prarit Bhargava fixed this issue with fda78d7a0ead ("PCI/MSI:
Stop disabling MSI/MSI-X in pci_device_shutdown()").
There is no automated way to set this parameter, so it's not very useful
for distributions or end users. It's really only useful for debugging, and
we have "pci=nomsi" for that purpose.
Revert 7570a333d8b0 to remove the "pcie_hp=nomsi" parameter.

Some PCIe features (AER, DPC, hotplug, PME) can be managed by either the
platform firmware or the OS, so the host bridge driver may have to request
permission from the platform before using them. On ACPI systems, this is
done by negotiate_os_control() in acpi_pci_root_add().
The PCIe port driver later uses pcie_port_platform_notify() and
pcie_port_acpi_setup() to figure out whether it can use these features.
But all we need is a single bit for each service, so these interfaces are
needlessly complicated.
Simplify this by adding bits in the struct pci_host_bridge to show when the
OS has permission to use each feature:
+ unsigned int native_aer:1; /* OS may use PCIe AER */
+ unsigned int native_hotplug:1; /* OS may use PCIe hotplug */
+ unsigned int native_pme:1; /* OS may use PCIe PME */
These are set when we create a host bridge, and the host bridge driver can
clear the bits corresponding to any feature the platform doesn't want us to
use.

No driver registers for PCIE_PORT_SERVICE_VC, so remove it.
This removes the VC "service" files from /sys/bus/pci_express/devices,
e.g., 0000:07:00.0:pcie108, 0000:08:04.0:pcie208 (all the files that
contained "8" as the last digit of the "pcieXXX" part). The port driver
created these files for PCIe port devices that have a VC Capability.
Since this reduces PCIE_PORT_DEVICE_MAXSERVICES and moves DPC down into the
spot where VC used to be, the DPC sysfs files will now be named "pcieXX8".
I don't think there's anything useful userspace can do with those files, so
I hope nobody cares about these filenames.
There is no VC driver that calls pcie_port_service_register(), so there
never was a /sys/bus/pci_express/drivers/vc directory.

The pcie_port_bus_type must be registered before drivers that depend on it
can be registered. Those drivers include:
pcied_init() # PCIe native hotplug driver
aer_service_init() # AER driver
dpc_service_init() # DPC driver
pcie_pme_service_init() # PME driver
Previously we registered pcie_port_bus_type from pcie_portdrv_init(), a
device_initcall. The callers of pcie_port_service_register() (above) are
also device_initcalls. This is fragile because the device_initcall
ordering depends on link order, which is not explicit.
Register pcie_port_bus_type from pci_driver_init() along with pci_bus_type.
This removes the link order dependency between portdrv and the pciehp, AER,
DPC, and PCIe PME drivers.

The "pcie_ports=compat" kernel parameter sets pcie_ports_disabled, which is
intended to disable the PCIe port driver. But even when it was disabled,
we registered pcie_portdriver so we could work around a BIOS PME issue (see
fe31e69740ed ("PCI/PCIe: Clear Root PME Status bits early during system
resume")).
Registering the driver meant that the pcie_portdrv_probe() path called
pci_enable_device(), pci_save_state(), pm_runtime_set_autosuspend_delay(),
pm_runtime_use_autosuspend(), etc., even when the driver was disabled.
We've since moved the BIOS PME workaround from the port driver to the core,
so stop registering the PCIe port driver in compat mode.
This means "pcie_ports=compat" will now be basically the same as turning
off CONFIG_PCIEPORTBUS completely.

Per PCIe r4.0, sec 6.1.6, Root Complex Event Collectors can generate PME
interrupts on behalf of Root Complex Integrated Endpoints.
Linux does not currently enable PME interrupts from RC Event Collectors,
but fe31e69740ed ("PCI/PCIe: Clear Root PME Status bits early during system
resume") suggests PME interrupts may be enabled by the platform for ACPI-
based runtime wakeup.
Clear the PCIe PME Status bit for Root Complex Event Collectors during
resume, just like we already do for Root Ports.
If the BIOS enables PME interrupts for an event collector and neglects to
clear the status bit on resume, this change should fix the same bug as
fe31e69740ed (PMEs not working after waking from a sleep state), but for
Root Complex Integrated Endpoints.

Add pcie_bandwidth_capable() to compute the max link bandwidth supported by
a device, based on the max link speed and width, adjusted by the encoding
overhead.
The maximum bandwidth of the link is computed as:
max_link_width * max_link_speed * (1 - encoding_overhead)
2.5 and 5.0 GT/s links use 8b/10b encoding, which reduces the raw bandwidth
available by 20%; 8.0 GT/s and faster links use 128b/130b encoding, which
reduces it by about 1.5%.
The result is in Mb/s, i.e., megabits/second, of raw bandwidth.

This commit has fix for RX traffic issues when we stress test the driver
with continuous ifconfig up/down under very high traffic conditions.
Reason for the issue is that, in existing liquidio_stop function NAPI is
disabled even before actual FW/HW interface is brought down via
send_rx_ctrl_cmd(lio, 0). Between time frame of NAPI disable and actual
interface down in firmware, firmware continuously enqueues rx traffic to
host. When interrupt happens for new packets, host irq handler fails in
scheduling NAPI as the NAPI is already disabled.
After "ifconfig <iface> up", Host re-enables NAPI but cannot schedule it
until it receives another Rx interrupt. Host never receives Rx interrupt as
it never cleared the Rx interrupt it received during interface down
operation. NIC Rx interrupt gets cleared only when Host processes queue and
clears the queue counts. Above anomaly leads to other issues like packet
overflow in FW/HW queues, backpressure.
Fix:
This commit fixes this issue by disabling NAPI only after informing
firmware to stop queueing packets to host via send_rx_ctrl_cmd(lio, 0).
send_rx_ctrl_cmd is not visible in the patch as it is already there in the
code. The DOWN command also waits for any pending packets to be processed
by NAPI so that the deadlock will not occur.
