Store the Tx data buffer of MAX_DATA_SIZE bytes as part of CE descriptor
debug information. Add sysfs API to dump the CE descriptor+data debug
information on console.
The CE descriptor and MAX_DATA_SIZE bytes are stored for Tx packets which
would be used to debug any CE related issues.

When the wlan driver is suspending, the last thing it does is check to
see if the firmware has indicated a wakeup during the suspend process.
This is done by checking the initial wakeup flag, which is set when a
specific copy engine payload is received from firmware. For the new
dedicated wake MSI, only the wake signal is received, no payload. When
the wake MSI is toggled, set the initial wakeup flag to prevent race
conditions during the suspend process.

Spinlock "lro_unloading_lock" was required to synchronize the LRO

With LRO moved to qdf and LRO is tied to hif_napi, LRO instance is

This can lead to unclocked access and followed by NOC errors.
In Rx path Interrupt Status and src/dst read index are directly

Avoid direct access to below registers if target is crashed due

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
