* Uses the attributes defined in
* enum qca_wlan_vendor_attr_tdls_disc_rsp_ext.
*
* @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
* (ex: 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 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 timeout since
* 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.
