* @QCA_WLAN_VENDOR_ATTR_MDNS_OFFLOAD_ENABLE: Required (flag)
* Enable mDNS offload. This attribute is mandatory to enable

* is disabled.
*
* @QCA_WLAN_VENDOR_ATTR_MDNS_OFFLOAD_TABLE: Nested attribute containing

* attribute is mandatory when enabling the feature, and not required when
* disabling the feature.
*
* @QCA_WLAN_VENDOR_ATTR_MDNS_OFFLOAD_ENTRY: Nested attribute containing
* the following attributes:
* %QCA_WLAN_VENDOR_ATTR_MDNS_OFFLOAD_FQDN
* %QCA_WLAN_VENDOR_ATTR_MDNS_OFFLOAD_ANSWER_RESOURCE_RECORDS_COUNT
* %QCA_WLAN_VENDOR_ATTR_MDNS_OFFLOAD_ANSWER_PAYLOAD
*
* @QCA_WLAN_VENDOR_ATTR_MDNS_OFFLOAD_FQDN: Required Null terminated string
* attribute. It consists of a hostname and ".local" as the domain name.
* The character set is limited to UTF-8 encoding. The maximum allowed size
* is 64 bytes. It is used to compare the domain in the "QU" query.
* Only 1 FQDN is supported per vdev.
* For example: myphone.local
*
* @QCA_WLAN_VENDOR_ATTR_MDNS_OFFLOAD_ANSWER_RESOURCE_RECORDS_COUNT: Required
* u16 attribute. It specifies the total number of resource records present
* in the answer section of the answer payload. This attribute is needed by the
* firmware to populate the mDNS response frame for mDNS queries without having
* to parse the answer payload.
*
* @QCA_WLAN_VENDOR_ATTR_MDNS_OFFLOAD_ANSWER_PAYLOAD: Required binary blob
* attribute sent by the mdnsResponder from userspace. It contains resource
* records of various types (e.g., A, AAAA, PTR, TXT) and service list. This
* payload is passed down to the firmware and is transmitted in response to
* mDNS queries.
* The maximum supported size of the answer payload is 1500 bytes.
