Abstraction layer for vdev subtype is added to solve
subtype mismatch and to give flexible compatibility
among different firmware revisions.
For instance, 10.2 and 10.4 firmware has different
definition of their vdev subtypes for Mesh.
10.4 defined subtype 6 for 802.11s Mesh while 10.2 uses 5.
Hence use the abstraction API to get right subtype to use.

WMI_10_4_SERVICE_MESH bit is for non IEEE802.11s Mesh.
Hence rename it to WMI_10_4_SERVICE_MESH_NON_11S.
Also add _11S as post-fix to each of WMI_SERVICE_MESH and
WMI_VDEV_SUBTYPE_MESH specifying the service is for 11s Mesh.
This will help users to distinguish 11s Mesh from non 11s Mesh.

QCA988X firmware starting from 10.2.4.70.12-2 has capability to support

Hence apply Mesh subtype according to the WMI service map.
Firmware will allows unicast, broadcast, multicast, and WDS frame
(FromDS = 1 and ToDS = 1) to be received via the interface, once Mesh
subtype is used.

Of a word in struct htt_data_tx_desc htt version >= 3.4 firmware uses
LSB 16-bit for frequency configuration which is used for offchannel tx
and MSB 16-bit is for peerid. But other firmwares using version 2.X
(10.1, 10.2.2, 10.2.4 and 10.4) are using 32-bit for peerid in htt tx
desc. So far no issue is found with the existing code setting peerid and
freq for HTT version 2.X, this could be mainly because of 0 as frequecy
(home channel) is being always passed with those firmwares. There may be
issues when non-zero freq is passed with firmware using < 3.4 htt version.
To be safe use target_version_major and target_version_minor along with
htt-op-version before configuring peer id and freq in htt tx desc. This
patch extends ath10k_mac_tx_frm_has_freq() to check for htt_op_version_tlv
and uses the helper while setting peerid in htt_tx_desc.

European Union has made it mandatory that all devices working in 2.4 GHz
has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
beginnig this year. The standard basically speaks about interferences
in 2.4Ghz band.
For example, when 802.11 device detects interference, TX must be stopped
as long as interference is present.
Adaptive CCA is a feature, when enabled the device learns from the
environment and configures CCA levels adaptively. This will improve
detecting interferences and the device can stop trasmissions till the
interference is present eventually leading to good performances in
varying interference conditions.
The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
QCA988X.

Add support for mesh to ath10k. We simply use an AP virtual interface
in the firmware in order to enable beaconing without TSF adoption, and
use the raw (802.11) transmit mode.
Due to firmware limitations, the firmware must operate in raw
(non-native 802.11) mode. As this is configured at firmware init time,
a new "rawmode" modparam is added, and mesh interfaces are available
only if rawmode=true. The firmware must advertise support for rawmode;
tested successfully with firmware 10.2.4.70.6-2.
When the module is loaded with (newly implemented) modparam rawmode=1, it
will enable operating an open mesh STA via something like the following:
ip link set wlan0 down
iw dev wlan0 set type mp
ip link set wlan0 up
iw dev wlan0 set freq 5745 80 5775
