Add QCA vendor subcommand to request audio transport switch
Add a new sub command QCA_NL80211_VENDOR_SUBCMD_AUDIO_TRANSPORT_SWITCH to request the audio data transport switch in both the command and event path. This is used when two or more audio data transports are available between peers. Signed-off-by: Purushottam Kushwaha <quic_pkushwah@quicinc.com>

* @QCA_NL80211_VENDOR_SUBCMD_AUDIO_TRANSPORT_SWITCH: This vendor subcommand is
|

* used to configure and indicate the audio transport switch in both

* command and event paths. This is used when two or more audio transports
|
||||
* (e.g., WLAN and Bluetooth) are available between peers.
|
||||
*
|
||||
* If the driver needs to perform operations like scan, connection,
|
||||
* roaming, RoC, etc. and AP concurrency policy is set to either
|
||||
* QCA_WLAN_CONCURRENT_AP_POLICY_GAMING_AUDIO or
|
||||
* QCA_WLAN_CONCURRENT_AP_POLICY_LOSSLESS_AUDIO_STREAMING, the driver sends
|
||||
* audio transport switch event to userspace. Userspace application upon
|
||||
* receiving the event, can try to switch to the requested audio transport.
|
||||
* The userspace uses this command to send the status of transport
|
||||
* switching (either confirm or reject) to the driver using this
|
||||
* subcommand. The driver continues with the pending operation either upon
|
||||
* receiving the command from userspace or after waiting for a timeout from
|
||||
* sending the event to userspace. The driver can request userspace to
|
||||
* switch to WLAN upon availability of WLAN audio transport once after the
|
||||
* concurrent operations are completed.
|
||||
*
|
||||
* Userspace can also request audio transport switch from non-WLAN to WLAN
|
||||
* using this subcommand to the driver. The driver can accept or reject
|
||||
* depending on other concurrent operations in progress. The driver returns
|
||||
* success if it can allow audio transport when it receives the command or
|
||||
* appropriate kernel error code otherwise. Userspace indicates the audio
|
||||
* transport switch from WLAN to non-WLAN using this subcommand and the
|
||||
* driver can do other concurrent operations without needing to send any
|
||||
* event to userspace. This subcommand is used by userspace only when the
|
||||
* driver advertises support for
|
||||
* QCA_WLAN_VENDOR_FEATURE_ENHANCED_AUDIO_EXPERIENCE_OVER_WLAN.
|
||||
*
|
||||
* The attributes used with this command are defined in enum
|
||||
* qca_wlan_vendor_attr_audio_transport_switch.
