A probe response built by a P2P GO should contain:
1. CSA/eCSA IE when relevant
2. If the corresponding probe request had P2P IE, then
need to add P2P IE with NOA attributes.
However, the NOA attributes and the updated channel switch
counter are known only to the FW. The solution is that FW
will send a notification with the relevant probe response
data and the driver will save it and update the probe
response accordingly.

The tid for Non-QOS frames is set to IWL_MAX_TID_COUNT. This value
is also used for configuring the queue for non-QOS data. However, this
tid is used by the FW for management queues. As a result, the FW
does not encrypt non-QOS data frames.
Fix this by setting the tid for non-QOS data frames to zero, which
is a valid value for data frames in the FW.
This also fixes a bug in sending multicast frames, where the queues
are allocated with tid == 0, but are sent with tid == 8, which may
lead to unexpected behavior.

Upon first calling read() on a debugfs file, invoke
iwl_dbgfs_##name##_read and store the response buffer on the heap, so
subsequent read() calls don't need to invoke said function again.
This is done because cat etc will call read() repeatedly until EOF is
reached (or read() returns 0), which in the current implementation will
cause said function to be invoked multiple times.
With the current implementation this can also cause buggy behavior in
some weird edge cases where the first invocation returns a string of
length n, and the second of length m>n: The last m-n characters of
the second invocation will be printed to screen.

Fix a bug in the way we handled VF queues, by always showing stats for
the maximum number of queues, even if they aren't allocated. It is not
safe to change the number of strings reported to ethtool, as grabbing
statistics occurs over multiple ethtool ops for which the rtnl_lock()
cannot be held the entire time.
Avoid this by always reporting queue stats for the maximum number of
queues in the netdevice. Share some of the helper functionality for
adding stats with the PF code in i40e_ethtool_stats.h
This should reduce the chance of potential future bugs, and make adding
new statistics easier.
Note for the queue stats, unlike the PF driver we do not keep an array
of queue pointers, but an array of queues, so care must be taken to
avoid accessing queue memory that hasn't yet been allocated.

Use an i40e_stats array to handle the queue stats, instead of coding
similar functionality separately. Because of how the queue stats are
accessed on some kernels, we can't easily use i40e_add_ethtool_stats.
Instead, implement a separate helper, i40e_add_queue_stats, which we'll
use instead. This helper will correctly implement the
u64_stats_fetch_begin_irq logic and allow retries until successful. We
share the most complex code by re-using i40e_add_one_ethtool_stat.
This logic additionally easily supports skipping disabled rings by using
a ternary operator before calling the u64_stats_fetch_begin_irq()
function, so that we correctly zero-out the stats values without having
to perform two separate sections of code.
This significantly reduces the boiler plate code in
i40e_get_ethtool_stats, and helps keep the complex logic contained to as
few functions as possible.
With this patch, we've finally converted all the statistics to use the
helpers and the i40e_stats function.

Without a valid of_node in struct device we can't find the mvpp2 port

switch connected to the &cp1_eth2 port:
&cp1_mdio {

...
ports {
...
port@5 {
reg = <5>;

3. Add two response lists for lio_process_ordered_list to process the

the pool after their requestors have finished processing the responses.
OCTEON_ZOMBIE_SC_LIST response list keeps all sc's which have got
LIO_SC_MAX_TMO_MS timeout.
When an sc gets a hard timeout, lio_process_order_list() will recheck
its status 1 ms later. If the status has not updated by the firmware at
that time, the sc will be removed from OCTEON_DONE_SC_LIST response list
to OCTEON_ZOMBIE_SC_LIST response list. The sc's in the
OCTEON_ZOMBIE_SC_LIST response list will be freed when the driver is
