In some corner cases, the peer handing an incoming ADD_ADDR option, can
receive a retransmitted ADD_ADDR for the same address before the subflow
creation completes.
We can avoid the above issue by generating and sending the ADD_ADDR echo
before starting the MPJ subflow connection.
This slightly changes the behaviour of the packetdrill tests as the
ADD_ADDR echo packet is sent earlier.

Network drivers can call to netif_get_num_default_rss_queues to get the
default number of receive queues to use. Right now, this default number
is min(8, num_online_cpus()).
Instead, as suggested by Jakub, use the number of physical cores divided
by 2 as a way to avoid wasting CPU resources and to avoid using both CPU
threads, but still allowing to scale for high-end processors with many
cores.
As an exception, select 2 queues for processors with 2 cores, because
otherwise it won't take any advantage of RSS despite being SMP capable.
Tested: Processor Intel Xeon E5-2620 (2 sockets, 6 cores/socket, 2
threads/core). NIC Broadcom NetXtreme II BCM57810 (10GBps). Ran some
tests with `perf stat iperf3 -R`, with parallelisms of 1, 8 and 24,
getting the following results:
- Number of queues: 6 (instead of 8)
- Network throughput: not affected
- CPU usage: utilized 0.05-0.12 CPUs more than before (having 24 CPUs
this is only 0.2-0.5% higher)
- Reduced the number of context switches by 7-50%, being more noticeable
when using a higher number of parallel threads.

The DSDT for the Asus TF103C specifies a IOAPIC IRQ for the HCI -> host IRQ
but this is not correct. Unlike the previous entries in the table, this
time the correct GPIO to use instead is known; and the TF103C is battery
powered making runtime-pm support more important.
Extend the bcm_broken_irq_dmi_table mechanism to allow specifying the right
GPIO instead of just always disabling runtime-pm and add an entry to it for
the Asus TF103C.

Fix the following kernel oops in btmtksdio_interrrupt

[ 14.339168] kthread+0x148/0x3ac
[ 14.339176] ret_from_fork+0x10/0x30
That happened because hdev->power_on is already called before
sdio_set_drvdata which btmtksdio_interrupt handler relies on is not
properly set up.
The details are shown as the below: hci_register_dev would run
queue_work(hdev->req_workqueue, &hdev->power_on) as WQ_HIGHPRI
workqueue_struct to complete the power-on sequeunce and thus hci_power_on
may run before sdio_set_drvdata is done in btmtksdio_probe.
The hci_dev_do_open in hci_power_on would initialize the device and enable
the interrupt and thus it is possible that btmtksdio_interrupt is being
called right before sdio_set_drvdata is filled out.
When btmtksdio_interrupt is being called and sdio_set_drvdata is not filled
, the kernel oops is going to happen because btmtksdio_interrupt access an
uninitialized pointer.

Another subset of the more recent batch of Chinese clones aren't
specs-compliant and seem to lock up whenever they receive a
HCI_OP_SET_EVENT_FLT with flt_type set to zero/HCI_FLT_CLEAR_ALL,
which on Linux (until the recent HCI state-machine refactor) happened
right at BR/EDR setup. As there are other less-straightforward ways
of reaching those operations, this patch is still relevant.
So, while all the previous efforts to wrangle the herd of fake CSRs
seem to be paying off (and these also get detected as such) we
still need to take care of this quirk; testers seem to agree
that these dongles tend to work well enough afterwards.
From some cursory USB packet capture on Windows it seems like
that driver doesn't appear to use this clear-all functionality at all.
This patch was tested on some really popular AliExpress-style
dongles, in my case marked as "V5.0". Chip markings: UG8413,

Also, changed the benign dmesg print that shows up whenever the
generic force-suspend fails from bt_dev_err to bt_dev_warn;
it's okay and done on a best-effort basis, not a problem
if that does not work.
Also, swapped the HCI subver and LMP subver numbers for the Barrot
in the comment, which I copied wrong the last time around.

Some controllers have problems with being sent a command to clear
all filtering. While the HCI code does not unconditionally
send a clear-all anymore at BR/EDR setup (after the state machine
refactor), there might be more ways of hitting these codepaths
in the future as the kernel develops.

There is a conflict between MediaTek wmt event and msft vendor extension
logic in the core layer since 145373cb1b ("Bluetooth: Add framework for
Microsoft vendor extension") was introduced because we changed the type of
mediatek wmt event to the type of msft vendor event in the driver.
But the purpose we reported mediatek event to the core layer is for the
diagnostic purpose with that we are able to see the full packet trace via
monitoring socket with btmon. Thus, it is harmless we keep the original
type of mediatek vendor event here to avoid breaking the msft extension
function especially they can be supported by Mediatek future devices.

Add test where sender sends two message, each with own
data pattern. Reader tries to read first to broken buffer:
it has three pages size, but middle page is unmapped. Then,
reader tries to read second message to valid buffer. Test
checks, that uncopied part of first message was dropped
and thus not copied as part of second message.

Again new complaints surfaced that we had broken the ABI here,
although previously all the userspace tools had agreed that it
was their mistake and fixed it. Yet now there are cases (e.g.
RHEL) that want to run old userspace with newer kernels, and
thus are broken.
Since this is a bit of a whack-a-mole thing, change the whole
extensibility scheme of rfkill to no longer just rely on the
message lengths, but instead require userspace to opt in via a
new ioctl to a given maximum event size that it is willing to
understand.
By default, set that to RFKILL_EVENT_SIZE_V1 (8), so that the
behaviour for userspace not calling the ioctl will look as if
it's just running on an older kernel.

Datapath improvements in preparation for XDP multi buffer
This series contains general improvements for the datapath that are
useful for the upcoming XDP multi buffer support:
a. Non-linear legacy RQ: validate MTU for robustness, build the linear
part of SKB over the first hardware fragment (instead of copying the
packet headers), adjust headroom calculations to allow enabling headroom
in the non-linear mode (useful for XDP multi buffer).
b. XDP: do the XDP program test before function call, optimize
parameters of mlx5e_xdp_handle.
2) From Rongwei Liu, DR, reduce steering memory usage
Currently, mlx5 driver uses mlx5_htbl/chunk/ste to organize
steering logic. However there is a little memory waste.
This update targets to reduce steering memory footprint by:
a. Adjust struct member layout.
b. Remove duplicated indicator by using simple functions call.
With 500k TX rules(3 ste) plus 500k RX rules(6 stes), these patches
can save around 17% memory.
3) Three cleanup commits at the end of this series.

Per-flow mirroring with the VCAP IS2 TCAM (in itself handled as an
offload for tc-flower) is done by setting the MIRROR_ENA bit from the
action vector of the filter. The packet is mirrored to the port mask
configured in the ANA:ANA:MIRRORPORTS register (the same port mask as
the destinations for port-based mirroring).
Functionality was tested with:
tc qdisc add dev swp3 clsact
tc filter add dev swp3 ingress protocol ip \
flower skip_sw ip_proto icmp \
action mirred egress mirror dev swp1
and pinging through swp3, while seeing that the ICMP replies are
mirrored towards swp1.
