When using the firmware api it can fail simply because firmware does
not like the request or it fails due to issues in the host interface.
Currently, there is only a single error code which is confusing. So
adding a parameter to pass the firmware error separately and in case
of a firmware error always return -EBADE to user-space.

The protocol layer api defines callbacks for dongle commands.
Although not really well documented these should only return an
error code in case of an error, or 0 upon success. In the bcdc
protocol it can return value above 0 and we carry a fix in the
caller of the protocol layer api. This patch makes it adhere to
the intent of the api as described above.

Events processing requires locking of bus mutex, which is also used by
cfg80211 layer before calling several of cfg80211 callbacks. Since all
cfg80211 callbacks in qtnfmac driver also lock bus mutex, this
potentially may lead to a deadlock.
Do not use bus lock for event processing. Use RTNL lock instead to
serialize events and commands processing threads.

STA does not reconnect to the same AP after disconnect. The reason is
that STA is marked as disconnected in cfg80211 disconnect callback.
This is too early since in this case qtnfmac event handler skips
cfg80211_disconnected call when processing disconnect event from
the card. As a result, wdev is left in an inconsistent state.

Validate new interface combinations using wireless core checks when new

Update existing code handling configuration of supported interface
combinations. Current implementation is not complete since it does
not report multiple interface combinations which are incompatible
with each other. Instead current implementation packs all the
supported combinations into single entry.
In fact currently qsr10g wireless card supports the following
two distinct interface combinations:
1. STA/repeater: 1 STA and/or 1 AP
{
{ .max = 1, .types = NL80211_IFTYPE_AP},
{ .max = 1, .types = NL80211_IFTYPE_STA},
}
2. AP/mBSS
{
{ .max = 8, .types = NL80211_IFTYPE_AP},
}
The list of supported configuration is reported by firmware during
wireless card bring-up. Communication protocol between firmware
and host has been updated accordingly in order to accommodate passing
multiple interface combination entries.

Driver periodically samples all neighbors configured in device
in order to update the kernel regarding their state. When finding
an entry configured in HW that doesn't show in neigh_lookup()
driver logs an error message.
This introduces a race when removing multiple neighbors -
it's possible that a given entry would still be configured in HW
as its removal is still being processed but is already removed
from the kernel's neighbor tables.
Simply remove the error message and gracefully accept such events.

Hardware encryption seems to break encrypted unicast mgmt tx.
Unfortunately the hardware TXWI header does not have a bit to indicate
that a frame is software encrypted, so sw-encrypted frames need to use a
different WCID. For that to work, the CCMP PN needs to be generated in
software, which makes things a bit slower, so only do it for keys that
also need to tx management frames.

Centaur CPU has a constant frequency TSC and that TSC does not stop in
C-States. But because the corresponding TSC feature flags are not set for
that CPU, the TSC is treated as not constant frequency and assumed to stop
in C-States, which makes it an unreliable and unusable clock source.
Setting those flags tells the kernel that the TSC is usable, so it will
select it over HPET. The effect of this is that reading time stamps (from
kernel or user space) will be faster and more efficent.

Mike Christie reports:
Starting in 4.14 iscsi logins will fail around 50% of the time.
Problem appears to be that iscsi_target_sk_data_ready() callback may
return without doing anything in case it finds the login work queue
is still blocked in sock_recvmsg().
Nicholas Bellinger says:
It would indicate users providing their own ->sk_data_ready() callback
must be responsible for waking up a kthread context blocked on
sock_recvmsg(..., MSG_WAITALL), when a second ->sk_data_ready() is
received before the first sock_recvmsg(..., MSG_WAITALL) completes.
So, do this and invoke the original data_ready() callback -- in
case of tcp sockets this takes care of waking the thread.
Disclaimer: I do not understand why this problem did not show up before
tcp prequeue removal.

This patch prevents the thinkpad_acpi driver from warning about 2 event
codes returned for keyboard palm-detection. No behavioral changes,
other than suppressing the warning in the kernel log. The events are
still forwarded via acpi-netlink channels.
We could, optionally, decide to forward the event through a
input-switch on the tpacpi input device. However, so far no suitable
input-code exists, and no similar drivers report such events. Hence,
leave it an acpi event for now.
Note that the event-codes are named based on empirical studies. On the
ThinkPad X1 5th Gen the sensor can be found underneath the arrow key.
