Add QCA vendor interface to support Unsynchronized Service Discovery
Add a new QCA command QCA_NL80211_VENDOR_SUBCMD_USD and related attributes to support Unsynchronized Service Discovery (USD). Device in active subscriber role sends SDF frames with service information to find devices that advertise or publish the required services. Device address, operation type, instance id, service_id, channel info, service specific info, element container attribute, and timeout are sent to the driver to initiate USD publish or USD subscribe operation. The driver sends QCA_NL80211_VENDOR_SUBCMD_USD event with instance_id and the USD operation status. QCA_NL80211_VENDOR_SUBCMD_USD is also used to update publish operation and to cancel the publish or subscribe operation for a service. It also allows all the operations to be terminated using the USD flush command. Signed-off-by: Vinay Gannevaram <quic_vganneva@quicinc.com>
