Currently we do not have full support for broadcast from
a station inside a PBSS network.
We have a workaround where instead of broadcast we do a
unicast to every known station in the PBSS.
This workaround was performed only for P2P clients.
This fix will perform the broadcast workaround also for a
regular station inside a PBSS.

The code in wmi_call uses the wil->wmi_call completion
structure to wait for a reply.
In some scenarios, complete was called twice on the
completion structure. This happened mainly with a disconnect
event which can arrive both unsolicited and as a reply to
a disconnect request. In this case the completion structure
was left marked as "done" and the next wmi_call returned
immediately with a corrupted reply buffer. This caused
unexpected results including crashes.
Fix this by adding the missing call to reinit_completion.

By default, AP SME is handled by driver/FW.
In case disable_ap_sme is true, driver doesn't turn-on
WIPHY_FLAG_HAVE_AP_SME and the responsibility for
AP SME is passed to user space.
With AP SME disabled, driver reports assoc request frame
to user space which is then responsible for sending assoc
response frame and for sending NL80211_CMD_NEW_STATION.
Driver also reports disassoc frame to user space
which should then send NL80211_CMD_DEL_STATION.
NL80211_CMD_SET_STATION with NL80211_STA_FLAG_AUTHORIZED
is used by user space to allow/disallow data transmit.

8000 series adapters support filtering VXLAN, NVGRE and GENEVE traffic
based on inner fields, and when the NIC recognises such traffic, it
does not match unencapsulated traffic filters any more. So add catch-
all filters for encapsulated traffic on supporting platforms.
Although recognition of VXLAN and GENEVE is based on UDP ports, and thus
will not occur until the driver (on the primary PF) notifies the
firmware of UDP ports to use, NVGRE will always be recognised, hence
without this patch 8000 series adapters will drop all NVGRE traffic.

If the NIC is switched from full-featured to low-latency, encapsulated

The first patch by Oliver Hartkopp adds a netlink API to configure the
