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

In case of IPA hw version less than 3.0, only 32 bit DMA
address can be handled as it is only 32 bit compliant.
Because of this, setting DMA coherent mask of 37 when

Do IPA version based DMA coherent mask setting such that
when IPA hw version is less than 3.0, set DMA coherent mask

WLAN suspend/resume feature has tight dependency on APPS platform
suspend/resume support. On new targets APPS suspend/resume is not
supported until target is feature complete. In absence of APPS
suspend/resume support testing WLAN offload features become
difficult. Add unit test framework to test WLAN suspend/resume
features using private IOCTL command by simulating APPS
suspend/resume behaviour.
Trigger WLAN suspend:
iwpriv wlan0 wlan_suspend 0 0
To resume WLAN run a ping test from access point side and very 1st
ping request unicast packet should trigger wake up.
If FW is not waking up APPS then use below command to do a manual
wake up:
Trigger WLAN resume:
iwpriv wlan0 wlan_resume 0 0
