This patch fixes the following warning during boot:
do not call blocking ops when !TASK_RUNNING; state=1 set at
[<(ptrval)>] qca_setup+0x194/0x750 [hci_uart]
WARNING: CPU: 2 PID: 1878 at kernel/sched/core.c:6135
__might_sleep+0x7c/0x88
In qca_set_baudrate(), the current task state is set to
TASK_UNINTERRUPTIBLE before going to sleep for 300ms. It was then
restored to TASK_INTERRUPTIBLE. This patch sets the current task state
back to TASK_RUNNING instead.

In some cases we may get from FW errored frames with
UNKNOWN security type.
This may happen in unsecured aggregation flow, where
the first packet had a CRC error in the WEP bit, which
was followed by a failure to decrypt and was dropped.
The next frames in the aggregation "inherit" the bad metadata
of the first packet.
Make sure to drop such frames since RADA and other offloads
will not operate correctly which may have unexpected results.
In case of AP it also causes to TX AMSDU frames to the peers,
resulting with assert 0x104B.

As we keep the offloaded TC rules for NIC and e-switch in two different
places, make sure to return the number of offloaded flows according
to the use-case and not blindly from the priv.

For cases where the CRTC is inactive (DPMS off), where a modeset is not
required, yet the CRTC is still in the atomic state, we should not
attempt to update anything on it.
Previously, we were relying on the modereset_required() helper to check
the above condition. However, the function returns false immediately if
a modeset is not required, ignoring the CRTC's enable/active state
flags. The correct way to filter is by looking at these flags instead.

When a GID entry is invalid EAGAIN is returned. This is an incorrect error
code, there is nothing that will make this GID entry valid again in
bounded time.
Some user space tools fail incorrectly if EAGAIN is returned here, and
this represents a small ABI change from earlier kernels.
The first patch in the Fixes list makes entries that were valid before
to become invalid, allowing this code to trigger, while the second patch
in the Fixes list introduced the wrong EAGAIN.
Therefore revert the return result to EINVAL which matches the historical
expectations of the ibv_query_gid_type() API of the libibverbs user space
library.

David Ahern says:
====================
net: Add address attribute to control metric of prefix route
For use cases such as VRR (Virtual Router Redundancy) interface managers
want efficient control over the order of prefix routes when multiple
interfaces have addresses with overlapping/duplicate subnets.
Currently, if two interfaces have addresses in the same subnet, the order
of the prefix route entries is determined by the order in which the
addresses are assigned or the links brought up. Any actions like cycling
an interface up and down changes that order. This set adds a new attribute
for addresses to allow a user to specify the metric of the prefix route
associated with an address giving interface managers better and more
efficient control of the order of prefix routes.
Patches 1-3 refactor IPv6 address add functions to pass an ifa6_config
struct. The functions currently have a long list of arguments and adding
the metric just makes it worse. Because of the overall diff size in
moving the arguments to a struct, the change is done in stages to make
it easier to review starting with the bottom function and pushing the
struct up to callers in each successive patch.
Patch 4 introduces the new attribute.
Patches 5 and 6 add support for the new attribute to IPv4 and IPv6
addresses.
Patch 7 adds a set of test cases.
Patch 8 adds support to iproute2
Changes since RFC
- collapsed patches 1 and 3 into patch 2
- simplified stack variables in fib_modify_prefix_metric in patch 5

Start the conversion to ifa6_config with ipv6_add_addr. This is an argument

addr --> cfg->pfx

====================
Signed-off-by: David S. Miller <davem@davemloft.net>

So far, the PCI BAR0 register is used for triggering FW reset. However,
that is a legacy attitude and it is recommended to use MRSR to perform
reset instead. So do that. Move the reset into init() function as
the cmd interface needs to be used. With that, IRQ initialization needs
to be moved as well. As a side effect, the reset move simplifies
the devlink reload flow.

There is an exception in command interface processing in case the MRSR
register is written to. The register triggers FW reset and during the
reset FW returns an error. So handle this by ignoring this error while
writing to MRSR register.

VLAN 1 is internally used for untagged traffic. Prevent creation of
explicit netdevice for that VLAN, because that currently isn't supported
and leads to the NULL pointer dereference cited below.
Fix by preventing creation of VLAN devices with VID of 1 over mlxsw
devices or LAG devices that involve mlxsw devices.

In commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros
1525/QCA6174") we tried to address the non-working Atheros BT devices
by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME. This made
such devices working while it turned out to break other existing chips
with the very same USB ID, hence it was reverted afterwards.
This is another attempt to tackle the issue. The essential point to
use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM-
patching. And the previous attempt failed because btusb_setup_qca()
returns -ENODEV if the ROM version doesn't match with the expected
ones. For some devices that have already the "correct" ROM versions,
we may just skip the setup procedure and continue the rest.
So, the first fix we'll need is to add a check of the ROM version in
the function to skip the setup if the ROM version looks already sane,
so that it can be applied for all ath devices.
However, the world is a bit more complex than that simple solution.
Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's
0x0001 at the beginning of probing, so the device probe always aborts
here.
In this patch, we add another check of ROM version again, and if the
device needs patching, the probe continues. For that, a slight
refactoring of btusb_qca_send_vendor_req() was required so that the
probe function can pass usb_device pointer directly before allocating
hci_dev stuff.
