WMI RX event processing is very critical for WLAN driver and today
we are using kernel's shared event work queue. Shared event work
queue is used by many drivers and if any work submitted in shared
work queue takes longer time to finish then it directly impacts WLAN
control path processing.
Define a dedicated work queue for WMI RX event processing and use
it for WMI RX event handling.

In the error-path execution stream where number of tso segments
in a tso_descriptor, there was an assumption that the number would
be > 0 (normal case is 2). When it is zero, a segment at a wrong
index (-1=> (4M-1)) was being unmapped, which was a bad access.
Add code to make sure that the index in question is in the range.
Need still to understand the reason why num_segs were smaller (0)
then expected (2).

In hif_napi.c, we are calling this kernel API core_ctl_set_boost. This
API is only present in the kernel if the feature CONFIG_SCHED_CORE_CTL
is present. In case the feature is not present in the kernel, it will
result in a compilation error.
Create a new internal API hif_napi_core_ctl_set_boost as a wrapper
around the kernel API. The new API is stubbed in case the kernel feature
is not present.

The existing HIF NAPI blacklist feature uses irq_blacklist_on(off) APIs
which make a call to the userspace irq_balancer.
Replace these APIs with kernel API irq_modify_status to mark (or unmark) the
individual interrupts with IRQ_NO_BALANCING flag. Once marked, the
msm-irq-balancer will not be able to move the CE interrupts around.

Interrupt blacklisting in kernel 4.4 happens through a user-space
entity. The kernel APIs irq_blacklist_on(off) essentially send
a message to the user space service(irq balancer) and
therefore are not synchronous and do not guarantee that blacklisting
has actually taken effect. It will be granted with some latency
(userspace entity's processing delay).
Make blacklisting more robust by:
a) move irq (if it has been moved around after blacklist_on call
has been made and not yet honored) to the designated CPU
on IRQ reception
b) stop cpu_isolation in blacklisting mode boost API
c) modify NAPI stats to indicate blacklisting mode

The current implementation uses jiffies to calculate the yield time and
yields after 2 jiffies. The problem with this is that we end up yielding
anywhere between 1 - 2 jiffies as each jiffies are incremented by 10 ms
intervals. Sometimes we are taking more than 2 jiffies to yield. This
prevents the update of deferrable_timer if its being done at the same
CPU where hif_napi_poll is executing. This may result in the CPU
frequencies not being updated resulting in some fluctuations.
Use sched_clock kernel API to calculate the precise yield time.
Reduce the yield time to 10ms.

Currently the config ini "wlanLoggingFEToConsole" specifically talks
about enabling the logs to kmsg for FATAL and ERROR logs.
This cfg.ini item should not be specific to any log level, instead
it should just depict whether logging to console should be enabled
or not. Hence change wlanLoggingFEToConsole to wlanLoggingToConsole.

Intrabss forwarding logic turns around bcast (ARP) pkts on the
SAP with peer source addr. So a AST lookup on AddrY results will
route the pkt to HW and not FW which is not the design. Fix is to
enable lookup only on AddrX in SAP mode.

Fix passing NULL vdev object to object manager. Currently during unload
process, we are purging all the cmds in the cmd list. In this case
pointer vdev_id is passed as NULL since we wanted to clean up cmds
associated with all the vdevs. In wlan_serialization_purge_cmd_list()
vdev remains NULL in this scenario which results in an ASSERT in
wlan_objmgr_vdev_release_ref().
This change set will call wlan_objmgr_vdev_release_ref only if vdev is
not NULL.
