c0174ee280 wlcore/wl18xx: mesh: added initial mesh support for wl8
1. Added support for interface and role of mesh type.
2. Enabled enable/start of mesh-point role,
   and opening and closing a connection with a mesh peer.
3. Added multirole combination of mesh and ap
   under the same limits of dual ap mode.
4. Add support for 'sta_rc_update' opcode for mesh IF.
   The 'sta_rc_update' opcode is being used in mesh_plink.c.
Add support in wlcore to handle this opcode correctly for mesh
(as opposed to current implementation that handles STA only).
5. Bumped the firmware version to support new Mesh functionality

8cfb86003d mwifiex: Reduce endian conversion for REG Host Commands
For multiple REG Host Commands (e.g HostCmd_CMD_802_11_EEPROM_ACCESS,
HostCmd_CMD_MAC_REG_ACCESS etc.) "cpu_to_leX"-converted values are
saved to driver. So, "leX_to_cpu" conversion is required too many
times afterwards in driver.

This patch reduces the endian: conversion without saving "cpu_to_leX"
converted values in driver. This will convert endianness in prepare
command and command response path.

d41376ca8b mwifiex: mask PCIe interrupts before removal
The PCIe driver didn't mask the host interrupts before trying to tear
down. This causes lockups at reboot or rmmod when using MSI-X on 8997,
since the MSI handler gets confused and locks up the system.

Also tested on 8897, which does not support MSI-X (and wasn't
experiencing this same bug). No regressions seen there.

a63b09872c brcmfmac: delete interface directly in code that sent fw request
So far when receiving event about in-firmware-interface removal our
event worker was notifying listener and afterwards it was removing Linux
interface.

First of all it was resulting in slightly unexpected order. The listener
(del_virtual_intf callback) was (usually) returning with success before
we even called unregister_netdev(ice).

Please note this couldn't be simply fixed by changing order of calls in
brcmf_fweh_handle_if_event as unregistering interface earlier could free
struct brcmf_if.

Another problem of current implementation are possible lockups. Focus on
the time slot between calling event handler and removing Linux
interface. During that time original caller may leave (unlocking rtnl
semaphore) *and* another call to the same code may be done (locking it
again). If that happens our event handler will stuck at removing Linux
interface, it won't handle another event and will block process holding
rtnl lock.

This can be simply solved by unregistering interface in a proper
callback, right after receiving confirmation event from firmware. This
only required modifying worker to don't unregister on its own if there
is someone waiting for the event.

7947d3e075 mac80211: Add support for beacon report radio measurement
Add the following to support beacon report radio measurement
with the measurement mode field set to passive or active:
1. Propagate the required scan duration to the device
2. Report the scan start time (in terms of TSF)
3. Report each BSS's detection time (also in terms of TSF)

TSF times refer to the BSS that the interface that requested the
scan is connected to.

1d76250bd3 nl80211: support beacon report scanning
Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.

In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.

Supporting beacon report is required for Multi Band Operation (MBO).
