skb_put_padto() will free the skb if it fails to add the requested
padding to the skb. Drop the packet if we are unable to allocate a new
skb with the requested padding.

Print error logs in the callback by using pr_err_ratelimited
so that watchdog bark will not occur due to excessive logging
when the callback is triggered before probe is completed.

The qrtr driver can guarantee that the packet gets queued to the socket
but cannot guarantee the client process will get time to run if auto
sleep is enabled. This config will help mitigate missed packets on
systems where auto sleep is too aggressive.
Use the pm_wakeup_ws_event() api so a hard wakeup can be specified.
This will ensure a resume occurs if the data coming in happens while
the device is going into suspend.

In some cases system enters into suspend state before handling
incoming packets and cause delay in communication.
Add pm_wakup_event() to abort the suspend when a packet is received.
Force a wakeup when queueing packets to a socket. This is needed to
give userspace clients a chance to run if the device is going into
system suspend. The wakeup event should force the device to abort
suspend.
The only node that should not behave this way is the SLPI node because
sensor stream race conditions cause suspend issues and power drain
issues.
There was an update to add a device parameter into
wakeup_source_register().

Add a pool of SKBs that can be used when the system is in low memory
conditions. This pool will be shared between all nodes and replenished
by a worker function.

Add support to configure the node id through defconfig. This is useful
for targets that are unable to configure the node id through qrtr-ns
because of security reasons. The local node id can still be overridden
by the ns if it is capable.

Node ref count decrement and test is performed inside ept
sem lock while node lookup is done inside node spin lock.
This can sometime cause node lookup to succeed while parallely
node can be freed in node release function. This will further
use of node and will result in use after free.
Additionally hold ept smem lock before performing node lookup.
