We will use this Kconfig option to not only enable TAS/EST offload
but also other QoS features like Multiqueue priority descriptors
and MAC-Merge/Frame Preemption. TI_AM65_CPSW_QOS seems a more
appropriate Kconfig option name than TI_AM65_CPSW_TAS.

Some devices have errata due to which they cannot report ETH_ZLEN (60)
in the rx-min-frag-size. This was foreseen of course, and lldpad has
logic that when we request it to advertise addFragSize 0, it will round
it up to the lowest value that is _actually_ supported by the hardware.
The problem is that the selftest expects lldpad to report back to us the
same value as we requested.
Make the selftest smarter by figuring out on its own what is a
reasonable value to expect.

Add a variable RUN_IN_NETNS if the user wants to run all the selected tests
in namespace in parallel. With this, we can save a lot of testing time.
Note that some tests may not fit to run in namespace, e.g.
net/drop_monitor_tests.sh, as the dwdump needs to be run in init ns.
I also added another parameter -p to make all the logs reported separately
instead of mixing them in the stdout or output.log.
Nit: the NUM in run_one is not used, rename it to test_num.

So let's just re-define server_ns/client_ns to unique name.
At the same time update the namespace name in gro.sh and toeplitz.sh.

Sockets in bhash are also linked to bhash2, but TIME_WAIT sockets
are linked separately in tb2->deathrow.
Let's replace tb->owners iteration in inet_csk_bind_conflict() with
two iterations over tb2->owners and tb2->deathrow.
This can be done safely under bhash's lock because socket insertion/
deletion in bhash2 happens with bhash's lock held.
Note that twsk_for_each_bound_bhash() will be removed later.

bhash2 added a new member sk_bind2_node in struct sock to link
sockets to bhash2 in addition to bhash.
bhash is still needed to search conflicting sockets efficiently
from a port for the wildcard address. However, bhash itself need
not have sockets.
If we link each bhash2 bucket to the corresponding bhash bucket,
we can iterate the same set of the sockets from bhash2 via bhash.
This patch links bhash2 to bhash only, and the actual use will be
in the later patches. Finally, we will remove sk_bind2_node.

Later, we no longer link sockets to bhash. Instead, each bhash2
bucket is linked to the corresponding bhash bucket.
Then, we pass the bhash bucket to bhash2 allocation functions as
tb. However, tb is already used in inet_bind2_bucket_create() and
inet_bind2_bucket_init() as the bhash2 bucket.
To make the following diff clear, let's use tb2 for the bhash2 bucket

In bhash2, IPv4/IPv6 addresses are saved in two union members,
which complicate address checks in inet_bind2_bucket_addr_match()
and inet_bind2_bucket_match_addr_any() considering uninitialised
memory and v4-mapped-v6 conflicts.
Let's simplify that by saving IPv4 address as v4-mapped-v6 address
and defining tb2.rcv_saddr as tb2.v6_rcv_saddr.s6_addr32[3].
Then, we can compare v6 address as is, and after checking v4-mapped-v6,
we can compare v4 address easily. Also, we can remove tb2->family.
Note these functions will be further refactored in the next patch.

While checking port availability in bind() or listen(), we used only
bhash for all v4-mapped-v6 addresses. But there is no good reason not
to use bhash2 for v4-mapped-v6 non-wildcard addresses.
Let's do it by returning true in inet_use_bhash2_on_bind(). Then, we
also need to add a test in inet_bind2_bucket_match_addr_any() so that
::ffff:X.X.X.X will match with 0.0.0.0.

The atomicity violation occurs due to concurrent execution of set_min and
set_max funcs.Consider a scenario where setmin writes a new, valid 'min'
value, and concurrently, setmax writes a value that is greater than the
old 'min' but smaller than the new 'min'. In this case, setmax might check
against the old 'min' value (before acquiring the lock) but write its
value after the 'min' has been updated by setmin. This leads to a
situation where the 'max' value ends up being smaller than the 'min'
value, which is an inconsistency.
This possible bug is found by an experimental static analysis tool
developed by our team, BassCheck[1]. This tool analyzes the locking APIs
to extract function pairs that can be concurrently executed, and then
analyzes the instructions in the paired functions to identify possible
concurrency bugs including data races and atomicity violations. The above
possible bug is reported when our tool analyzes the source code of
Linux 5.17.
To resolve this issue, it is suggested to encompass the validity checks
within the locked sections in both set_min and set_max funcs. The
modification ensures that the validation of 'val' against the
current min/max values is atomic, thus maintaining the integrity of the
settings. With this patch applied, our tool no longer reports the bug,
with the kernel configuration allyesconfig for x86_64. Due to the lack of
associated hardware, we cannot test the patch in runtime testing, and just
verify it according to the code logic.

In case of an incomplete command or a command with a null identifier 2
reject packets will be sent, one with the identifier and one with 0.
Consuming the data of the command will prevent it.
This allows to send a reject packet for each corrupted command in a
multi-command packet.

when Bluetooth set the event mask and enter suspend, the controller
has hci mode change event coming, it cause controller can not enter
sleep mode. so it should to set the hci mode change event mask before
enter suspend.

Serdev recv_buf() callback is supposed to return the amount of bytes
consumed, therefore an int in between 0 and count.
Do not return negative number in case of issue, just print an error and
return count. This fixes a WARN in ttyport_receive_buf().

Serdev recv_buf() callback is supposed to return the amount of bytes
consumed, therefore an int in between 0 and count.
Do not return a negative number in case of issue, just print an error
and return count. Before this change, in case of error, the returned
negative number was internally converted to 0 in ttyport_receive_buf,
now when the receive buffer is corrupted we return the size of the whole
received data (`count`). This should allow for better recovery in case
receiver/transmitter get out of sync if some data is lost.
This fixes a WARN in ttyport_receive_buf().

For QCA2066 HFP offload, HCI_Configure_Data_Path is not required since
present HCI_Enhanced_Setup_Synchronous_Connection is enough to configure
non-HCI data transport path when set both Input_Data_Path and
Output_Data_Path parameters as 0x01, as is implemented by this change.

For some controllers such as QCA2066, it does not need to send
HCI_Configure_Data_Path to configure non-HCI data transport path to support
HFP offload, their device drivers may set hdev->get_codec_config_data as
NULL, so Explicitly add this non NULL checking before calling the function.

When a PA sync socket is closed, the associated hcon is also unlinked
and cleaned up. If there are no other hcons marked with the
HCI_CONN_PA_SYNC flag, HCI_OP_LE_PA_TERM_SYNC is sent to controller.
Between the time of the command and the moment PA sync is terminated
in controller, residual BIGInfo reports might continue to come.
This causes a new PA sync hcon to be added, and a new socket to be
notified to user space.
This commit fixs this by adding a flag on a Broadcast listening
socket to mark when the PA sync child has been closed.
This flag is checked when BIGInfo reports are indicated in
iso_connect_ind, to avoid recreating a hcon and socket if
residual reports arrive before PA sync is terminated.
