This was added to mitigate the effects of too much sampling on devices that

Now that the sampling algorithm is improved, this code path no longer performs

The biggest flaw in current minstrel_ht is the fact that it needs way too
many probing packets to be able to quickly find the best rate.
Depending on the wifi hardware and operating mode, this can significantly
reduce throughput when not operating at the highest available data rate.
In order to be able to significantly reduce the amount of rate sampling,
we need a much smarter selection of probing rates.
The new approach introduced by this patch maintains a limited set of
available rates to be tested during a statistics window.
They are split into distinct categories:
- MINSTREL_SAMPLE_TYPE_INC - incremental rate upgrade:
Pick the next rate group and find the first rate that is faster than
the current max. throughput rate
- MINSTREL_SAMPLE_TYPE_JUMP - random testing of higher rates:
Pick a random rate from the next group that is faster than the current
max throughput rate. This allows faster adaptation when the link changes
significantly
- MINSTREL_SAMPLE_TYPE_SLOW - test a rate between max_prob, max_tp2 and
max_tp in order to reduce the gap between them
In order to prioritize sampling, every 6 attempts are split into 3x INC,
2x JUMP, 1x SLOW.
Available rates are checked and refilled on every stats window update.
With this approach, we finally get a very small delta in throughput when
comparing setting the optimal data rate as a fixed rate vs normal rate
control operation.

In order to more gracefully be able to fall back to lower rates without too
much throughput fluctuations, initialize all untested rates below tested ones
to the maximum probabilty of higher rates.
Usually this leads to untested lower rates getting initialized with a
probability value of 100%, making them better candidates for fallback without
having to rely on random probing

Sparse started warning on this function because we can potentially
return an uninitialized value. The reason is that if the caller
passes a min_bw value that is higher then the last value in bws[], we
will not go into the loop and reg_rule will remain initialized. This
cannot happen because the only caller of this function uses either 1
or 20 in min_bw, but the function will be more robust if we
pre-initialize the value.

This patch unifies sending control port frames
over nl80211 and AF_PACKET sockets a little more.
Before this patch, EAPOL frames got QoS prioritization
only when using AF_PACKET sockets.
__ieee80211_select_queue only selects a QoS-enabled queue
for control port frames, when the control port protocol
is set correctly on the skb. For the AF_PACKET path this
works, but the nl80211 path used ETH_P_802_3.
Another check for injected frames in wme.c then prevented
the QoS TID to be copied in the frame.
In order to fix this, get rid of the frame injection marking
for nl80211 ctrl port and set the correct ethernet protocol.
Please note:
An erlier version of this path tried to prevent
frame aggregation for control port frames in order to speed up
the initial connection setup a little. This seemed to cause
issues on my older Intel dvm-based hardware, and was therefore
removed again. Future commits which try to reintroduce this
have to check carefully how hw behaves with aggregated and
non-aggregated traffic for the same TID.

Use napi to reduce overhead on rx interrupts.
Driver used to interrupt kernel for every Rx packet, this could
affect both system and network performance. NAPI is a mechanism that
uses polling when processing huge amount of traffic, by doing this
the number of interrupts can be decreased.
Network performance can also benefit from this patch. Since TCP
connection is bidirectional and acks are required for every several
packets. These ack packets occupie the PCI bus bandwidth and could
lead to performance degradation.
When napi is used, GRO receive is enabled by default in the mac80211
stack. So mac80211 won't pass every RX TCP packets to the kernel TCP
network stack immediately. Instead an aggregated large length TCP packet
will be delivered.
This reduces the tx acks sent and gains rx performance. After the patch,
the Rx throughput increases about 25Mbps in 11ac.

As of [1], we no longer want EXT4_KUNIT_TESTS and others to `select`
their deps. This means it can get harder to get all the right things
selected as we gain more tests w/ more deps over time.
This patch (and [2]) proposes we store kunitconfig fragments in-tree to
represent sets of tests. (N.B. right now we only have one ext4 test).
There's still a discussion to be had about how to have a hierarchy of
these files (e.g. if one wanted to test all of fs/, not just fs/ext4).
But this fragment would likely be a leaf node and isn't blocked on
deciding if we want `import` statements and the like.
Usage
=====
Before [2] (on its way to being merged):
$ cp fs/ext4/.kunitconfig .kunit/
$ ./tools/testing/kunit/kunit.py run
After [2]:
$ ./tools/testing/kunit/kunit.py run --kunitconfig=fs/ext4/.kunitconfig

* The bit about .gitignore exluding it by default is now a con, however.
* But there are a lot of directories with files that begin with "k" and

* This is the name kunit.py expects right now, so some people are used

methods. In addition, it is referenced from several hash tables.
The lifetime of the ct entry object was not managed which triggered race
conditions as in the following kasan dump:

Devlink reload can't be allowed on lag devices since reloading one lag
device will cause traffic on the bond to get stucked.
Users who wish to reload a lag device, need to remove the device from
the bond, and only then reload it.

In lag mode, setting roce enabled/disable of lag device have no effect.
e.g.: bond device (roce/vf_lag) roce status remain unchanged.
Therefore disable it and add an error message.

In dual port mode, setting roce enabled/disable for the slave device
have no effect. e.g.: the slave device roce status remain unchanged.
Therefore disable it and add an error message.
Enable or disable roce of the master device affect both master and slave
devices.

Devlink reload can't be allowed on a multi port slave device, because
reload of slave device doesn't take effect.
The right flow is to disable devlink reload for multi port slave
device. Hence, disabling it in mlx5_core probing.
