Fix the current driver mgmt frame is not respecting the basic rates field
provided by the AP and then unconditionally is using the lowest (1 or 6
Mbps) rate.
For example, if the AP only supported basic rate {24, 36, 48, 54} Mbps,
mt7921 cannot send mgmt frame with the rate not in the group. So,
instead, we pick up the lowest basic rate the AP can support to send.

mt7921 is mainly used in NB, CE and IoT application where battery life is
much concerned so the patch enabled PCIe ASPM by default to shut off the
clocks related PCIe as much as possible when MT7921 is either in suspend
state or in runtime pm to lower power consumption.
We still leave disable aspm as an option with module_param for users to
disable ASPM if necessary.

The spi-altera driver has two flavors: platform and dfl. I'm seeing
a case where I have both device types in the same machine, and they
are conflicting on the SPI ID:
... kernel: couldn't get idr
... kernel: WARNING: CPU: 28 PID: 912 at drivers/spi/spi.c:2920 spi_register_controller.cold+0x84/0xc0a
Both the platform and dfl drivers use the parent's driver ID as the SPI
ID. In the error case, the parent devices are dfl_dev.4 and
subdev_spi_altera.4.auto. When the second spi-master is created, the
failure occurs because the SPI ID of 4 has already been allocated.
Change the ID allocation to dynamic (by initializing bus_num to -1) to
avoid duplicate SPI IDs.

The current blk_mq_quiesce_queue() and blk_mq_unquiesce_queue() always
stops and starts the queue unconditionally. And there can be concurrent
quiesce/unquiesce coming from different unrelated code paths, so
unquiesce may come unexpectedly and start queue too early.
Prepare for supporting concurrent quiesce/unquiesce from multiple
contexts, so that we can address the above issue.
NVMe has very complicated quiesce/unquiesce use pattern, add one atomic
bit for makeiing sure that blk-mq quiece/unquiesce is always called in
pair.

When irdma_ws_add fails, irdma_ws_remove is used to cleanup the leaf node.
This lead to holding the qos mutex twice in the QP resume path. Fix this

irdma_ws_add. This skips the call to irdma_tc_in_use function which is not
needed in the error unwind cases.

and a perf diff with this patch:
0.92% +4.40% [nvme_core] [k] nvme_setup_cmd

This patch improves a few things:
- it fixes issue where ethtool -i reports that PR supports
priv-flags and tests when in fact it does not support them
- instead of using the same functions for both PF and PR ethtool ops,
this patch introduces separate ops for both cases and internal
functions with core logic.
- prevent accessing VF VSI while VF is not ready by calling
ice_check_vf_ready_for_cfg
- all PR specific functions in ethtool.c were moved to one place in
file
- instead overwriting n_priv_flags in ice_repr_get_drvinfo,
priv-flags code was moved from __ice_get_drvinfo to ice_get_drvinfo

Currently it is not possible to set/unset lb_en and lan_en flags
for advanced rules during their creation. Both flags are enabled
by default. In case of switchdev offloads for egress traffic we
need lb_en to be disabled. Because of that, we work around it by
updating the rule immediately after its creation.
This change allows us to set/unset those flags right away and it
gets rid of old workaround as well. Using ice_adv_rule_flags_info
structure we can pass info about flags we want to be set for
a given advanced rule. Flags are stored in flags_info.act.
Values from act would be used only if act_valid was set to true,
otherwise default values would be used.

Merge issues caused the check for switchdev mode has been inserted
in wrong place. It should be in ice_set_vf_trust not in ice_set_vf_mac.
Trusted VFs are forbidden in switchdev mode because they should
be configured only from the host side.
Fixes: 1c54c839935b ("ice: enable/disable switchdev when managing VFs")

The driver tried to work around missing completion events that occurred
while interrupts are disabled, by triggering a software interrupt
whenever we exit polling (but we had to have polled at least once).
This was causing a *lot* of extra interrupts for some workloads like
NVMe over TCP, which resulted in regressions in performance. It was also
visible when polling didn't prevent interrupts when busy_poll was
enabled.
Fix the extra interrupts by utilizing our previously unused 3rd ITR
(interrupt throttle) index and set it to 20K interrupts per second, and
then trigger a software interrupt within that rate limit.
While here, slightly refactor the code to avoid an overwrite of a local
variable in the case of wb_en = true.
