iwlwifi: mvm: assign cab queue to the correct station
Currently when configuring the cab queue the scheduler is configured
without station id - which results in station id 0.
In DQA mode this causes firmware to assert later on when the actual
station 0 is added with an empty tfd_queue_mask.
Fix that by configuring the queue to the broadcast station.
This is a bit trickier since the queue should not be included in the
tfd_queue_mask of the ADD_STA since it is a multicast queue, and the
tfd_queue_mask is only unicast queue. As a result the queue should be
enabled only after the broadcast station is added.

iwlwifi: mvm: use firmware station PM notification for AP_LINK_PS
When using RSS on 9000 series devices, we can't rely on processing the
received frames for station powersave handling, since they could be
processed on different CPUs and out of order.
In order to still manage the powersave of stations, the firmware sends
a notification on sleep->wake, wake->sleep and - for U-APSD - frames
received with PM while already sleeping (with the TID.)
With this, the driver can set AP_LINK_PS, which is required for real
parallel RX. In addition, this requires checking for PS-Poll frames

ath10k: fix copy engine 5 destination ring stuck
Firmware is running watchdog timer for tracking copy engine ring index
and write index. Whenever both indices are stuck at same location for
given duration, watchdog will be trigger to assert target. While
updating copy engine destination ring write index, driver ensures that
write index will not be same as read index by finding delta between these
two indices (CE_RING_DELTA).
HTT target to host copy engine (CE5) is special case where ring buffers
will be reused and delta check is not applied while updating write index.
In rare scenario, whenever CE5 ring is full, both indices will be referring
same location and this is causing CE ring stuck issue as explained
above. This issue is originally reported on IPQ4019 during long hour stress
testing and during veriwave max clients testsuites. The same issue is
also observed in other chips as well. Fix this by ensuring that write
index is one less than read index which means that full ring is
available for receiving data.

brcmfmac: fix out of bound access on clearing wowl wake indicator
Clearing the wowl wakeindicator happens with a rather odd
construction where the string "clear" is used to set the iovar
wowl_wakeind. This was implemented incorrectly as it caused an
out of bound access. Use an intermediate variable of correct
length and copy string in that. Problem was found using coverity.

wlcore: Fix config firmware loading issues
Booting multiple wl12xx and wl18xx devices using the same rootfs is
a pain. You currently have to symlink the right nvs file depending
on the wl12xx type.
For example, with wl1271-nvs.bin being a symlink to wl127x-nvs.bin
by default and trying to bring up a wl128x based device:
wlcore: ERROR nvs size is not as expected: 1113 != 912
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR firmware boot failed despite 3 retries
Note that wl18xx uses a separate config firmware wl18xx-conf.bin
that can be generated with tools using the following two git repos:
git.ti.com/wilink8-wlan/18xx-ti-utils
git.ti.com/wilink8-wlan/wl18xx_fw
So let's not configure the nvs file for wl18xx as it's not needed
AFAIK. If it turns out that we also need the nvs file for wl18xx,
we can just add it to the config firmware data for wl18xx.

data, and make sure we produce understandable warnings if something

sta_cmdresp.c:1053 mwifiex_create_custom_regdomain() warn: possible memory leak of 'regd'
Indeed, mwifiex_create_custom_regdomain() returns NULL in the
case that channel is missing in the TLV without freeing regd.
Moreover, some other error paths in this function return ERR_PTR
values which are assigned without checking to the regd field in
the mwifiex_adapter struct. The latter is only null-checked where
used.
Fix by freeing regd in the error path, and only update
priv->adapter->regd if the returned pointer is valid.

ip_tunnel: add collect_md mode to IPv4/IPv6 tunnels
Similar to geneve, vxlan, gre tunnels implement 'collect metadata' mode
in ipip, ipip6, ip6ip6 tunnels.

samples/bpf: add comprehensive ipip, ipip6, ip6ip6 test
the test creates 3 namespaces with veth connected via bridge.
First two namespaces simulate two different hosts with the same
IPv4 and IPv6 addresses configured on the tunnel interface and they
communicate with outside world via standard tunnels.
Third namespace creates collect_md tunnel that is driven by BPF
program which selects different remote host (either first or
second namespace) based on tcp dest port number while tcp dst
ip is the same.
This scenario is rough approximation of load balancer use case.
The tests check both traditional tunnel configuration and collect_md mode.

Similar to gre, vxlan, geneve tunnels allow IPIP6 and IP6IP6 tunnels

Unlike ipv4 code here it's possible to reuse ip6_tnl_xmit() function
for both collect_md and traditional tunnels.

Similar to gre, vxlan, geneve tunnels allow IPIP tunnels to

bpf_skb_[gs]et_tunnel_key() helpers can make use of it right away.
ovs can use it as well in the future (once appropriate ovs-vport
abstractions and user apis are added).
Note that just like in other tunnels we cannot cache the dst,
since tunnel_info metadata can be different for every packet.
