The ionic_wait_on_bit_lock() was a open-coded mutex knock-off
used only for protecting the queue reset operations, and there
was no reason not to use the real thing. We can use the lock
more correctly and to better protect the queue stop and start
operations from cross threading. We can also remove a useless
and expensive bit operation from the Rx path.
This fixes a case found where the link_status_check from a link
flap could run into an MTU change and cause a crash.

This patch adds u64_stats_update_* usage to protect access to 64-bit stats,
where necessary.
This is necessary for per-ring stats, because they are updated by the
driver directly, so there is a possibility for a partial read.
Other stats require no additional protection, e.g.:
* all MACSec stats are fetched directly from HW (under semaphore);
* nic/ndev stats (aq_stats_s) are fetched directly from FW (under mutex).

Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.
With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.
This driver makes use of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(),
pci_set_power_state() and pci_set_master() to do required operations. In
generic mode, they are no longer needed.
Change function parameter in both .suspend() and .resume() to
"struct device*" type. Use to_pci_dev() and dev_get_drvdata() to get
"struct pci_dev*" variable and drv data.

and this doesn't allow to add and support more speeds.
Convert custom link mode to generic Ethtool bitmap and definitions
(convenient Phylink shorthands are used for elegance and readability).
This allowed us to drop all conversions/mappings between the driver
and Ethtool.
This involves changes in qede and qedf as well, as they used definitions

wireless-drivers-next patches for v5.9
First set of patches for v5.9. This comes later than usual as I was
offline for two weeks. The biggest change here is moving Microchip
wilc1000 driver from staging. There was an immutable topic branch with
one commit moving the whole driver and the topic branch was pulled
both to staging-next and wireless-drivers-next. At the moment the only
reported conflict is in MAINTAINERS file, so I'm hoping the move
should go smoothly.
Other notable changes are ath11k getting 6 GHz band support and rtw88
supporting RTL8821CE. And there's also the usual fixes, API changes
and cleanups all over.
Major changes:
wilc1000
* move from drivers/staging to drivers/net/wireless/microchip
ath11k
* add 6G band support
* add spectral scan support
iwlwifi
* make FW reconfiguration quieter by not using warn level
rtw88
* add support for RTL8821CE

Adapt the Wake-on-Lan feature to the Cadence GEM Ethernet controller.
This controller has different register layout and cannot be handled by
previous code.
We disable completely interrupts on all the queues but the queue 0.
Handling of WoL interrupt is done in another interrupt handler
positioned depending on the controller version used, just between
suspend() and resume() calls.
It allows to lower pressure on the generic interrupt hot path by
removing the need to handle 2 tests for each IRQ: the first figuring out
the controller revision, the second for actually knowing if the WoL bit
is set.
Queue management in suspend()/resume() functions inspired from RFC patch
