Currently, IPA driver asserts if IPA FW loading
fails. Some environments do not have IPA FW
integrated and we should not crash at these cases.

Split the joint LAN_WAN producer pipe to two
pipes, one for LAN and one for WAN.
Use event based completion for the WAN pipe
instead of status based to improve UL performance.

SSR logic is executed during device shutdown. During device
shutdown the Linux tasks (processes) are moving to SIGKILL
state. If a DMA allocation from the kernel happens
in a context of a process in SIGKILL state and page migration
is needed, the allocation will fail.
Use GFP_ATOMIC allocation flag during SSR. This will
utilize the atomic memory pool and will not require page
migration.

On pipe setup, enable data path should happen for after
all pipe resources are allocated.
This change prevents a race condition where the pipe is enabled
before RX buffers are submitted to IPA.
Then, when buffers are submitted to IPA there is a race between
submitting the buffers and getting RX packets.

To avoid a race condition between init_completion() and complete()
which will cause a crash use reinit_completion() which is safe.

Adapt to latest changes to IPA micro-controller (IPA uC).
For pipe SUSPEND, IPA uC will fail in case the pipe is not empty.
IPA driver needs to insure pipe is empty and then issue a SUSPEND command.
For pipe DISABLE, pipe is already empty on SUSPEND,
IPA driver does not need to do ensure anything before
issuing a DISABLE command.
