When HCI_QUIRK_NON_PERSISTENT_SETUP is set by drivers,
it indicates that BT SoC will be completely powered OFF
during BT OFF. On next BT ON firmware must be downloaded
again. Holding UART port open during BT OFF is draining
the battery. Now during BT OFF, UART port is closed if
qurik HCI_QUIRK_NON_PERSISTENT_SETUP is set by clearing
HCI_UART_PROTO_READY proto flag. On next BT ON, UART
port is opened if HCI_UART_PROTO_READY proto flag is cleared.

On new Intel platform the device is provided with INT33E3 ID.
Append it to the list.
This will require ACPI_GPIO_QUIRK_ONLY_GPIOIO to be enabled because
the relevant ASL looks like:
UartSerialBusV2 ( ... )
GpioInt ( ... ) { ... }
GpioIo ( ... ) { ... }
which means that first GPIO resource is an interrupt, while we are expecting it
to be reset one (output). Do the same for host-wake because in case of
GpioInt() the platform_get_irq() will do the job and should return correct
Linux IRQ number. That said, host-wake GPIO can only be GpioIo() resource.
While here, drop commas in terminator lines.

Nowadays output function has a 'synack_type' argument that tells us when
the syn/ack is emitted via syncookies.
The request already tells us when timestamps are supported, so check
both to detect special timestamp for tcp option encoding is needed.
We could remove cookie_ts altogether, but a followup patch would
otherwise need to adjust function signatures to pass 'want_cookie' to
mptcp core.
This way, the 'existing' bit can be used.

Running a RX refill outside of NAPI context is inherently racy, even
though the worker is only started for an entirely idle RX ring.
>From the moment that the worker has replenished parts of the RX ring,
the HW can use those RX buffers, raise an IRQ and cause our NAPI code to
run concurrently to the RX refill worker.
Instead let the worker schedule our NAPI instance, and refill the RX
ring from there. Keeping accurate count of how many buffers still need
to be refilled also removes some quirky arithmetic from the low-level
code.

When preparing a buffer for RX refill, tolerate that it already has a
pool_entry attached. Otherwise we could easily leak such a pool_entry
when re-driving the RX refill after an error (from eg. do_qdio()).
This needs some minor adjustment in the code that drains RX buffer(s)
prior to RX refill and during teardown, so that ->pool_entry is NULLed
accordingly.

This is in fact 'disabled' in the spec, but there it's in a
place where that actually makes sense. In our internal data
structures, it doesn't really make sense, and in fact the
previous commit just fixed a bug in that area.
Make this safer by inverting the polarity from 'disabled' to
'enabled'.

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

With legacy PM hooks, it was the responsibility of a driver to manage PCI
states and also the device's power state. The generic approach is to let
PCI core handle the work.
e100_suspend() calls __e100_shutdown() to perform intermediate tasks.
__e100_shutdown() calls pci_save_state() which is not recommended.
e100_suspend() also calls __e100_power_off() which is calling PCI helper
functions, pci_prepare_to_sleep(), pci_set_power_state(), along with
pci_wake_from_d3(...,false). Hence, the functin call is removed and wol is
disabled as earlier using device_wakeup_disable().

states and also the device's power state. The generic approach is to let
PCI core handle the work.
ixgbe_suspend() calls __ixgbe_shutdown() to perform intermediate tasks.
__ixgbe_shutdown() modifies the value of "wake" (device should be wakeup
enabled or not), responsible for controlling the flow of legacy PM.
Since, PCI core has no idea about the value of "wake", new code for generic
PM may produce unexpected results. Thus, use "device_set_wakeup_enable()"
to wakeup-enable the device accordingly.

Remove legacy PM callbacks and use generic operations. With legacy code,
drivers were responsible for handling PCI PM operations like
pci_save_state(). In generic code, all these are handled by PCI core.
The generic suspend() and resume() are called at the same point the legacy
ones were called. Thus, it does not affect the normal functioning of the
driver.
__maybe_unused attribute is used with .resume() but not with .suspend(), as
.suspend() is called by .shutdown().
