+ * enum qca_wlan_vendor_attr_roaming_config_params: Attributes for data used by
+ * QCA_NL80211_VENDOR_SUBCMD_ROAM sub command.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_SUBCMD: Unsigned 32-bit value.
+ * Represents the different roam sub commands referred by
+ * enum qca_wlan_vendor_attr_roam_subcmd.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_REQ_ID: Unsigned 32-bit value.
+ * Represents the Request ID for the specific set of commands.
+ * This also helps to map specific set of commands to the respective
+ * ID / client. e.g., helps to identify the user entity configuring the
+ * Blacklist BSSID and accordingly clear the respective ones with the
+ * matching ID.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_WHITE_LIST_SSID_NUM_NETWORKS: Unsigned
+ * 32-bit value.Represents the number of whitelist SSIDs configured.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_WHITE_LIST_SSID_LIST: Nested attribute
+ * to carry the list of Whitelist SSIDs.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_WHITE_LIST_SSID: SSID (binary attribute,
+ * 0..32 octets). Represents the white list SSID. Whitelist SSIDs
+ * represent the list of SSIDs to which the firmware/driver can consider
+ * to roam to.
+ *
+ * The following PARAM_A_BAND_XX attributes are applied to 5GHz BSSIDs when
+ * comparing with a 2.4GHz BSSID. They are not applied when comparing two
+ * 5GHz BSSIDs.The following attributes are set through the Roaming SUBCMD -
+ * QCA_WLAN_VENDOR_ATTR_ROAM_SUBCMD_SET_GSCAN_ROAM_PARAMS.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_A_BAND_BOOST_THRESHOLD: Signed 32-bit
+ * value, RSSI threshold above which 5GHz RSSI is favored.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_A_BAND_PENALTY_THRESHOLD: Signed 32-bit
+ * value, RSSI threshold below which 5GHz RSSI is penalized.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_A_BAND_BOOST_FACTOR: Unsigned 32-bit
+ * value, factor by which 5GHz RSSI is boosted.
+ * boost=(RSSI_measured-5GHz_boost_threshold)*5GHz_boost_factor
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_A_BAND_PENALTY_FACTOR: Unsigned 32-bit
+ * value, factor by which 5GHz RSSI is penalized.
+ * penalty=(5GHz_penalty_threshold-RSSI_measured)*5GHz_penalty_factor
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_A_BAND_MAX_BOOST: Unsigned 32-bit
+ * value, maximum boost that can be applied to a 5GHz RSSI.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_LAZY_ROAM_HISTERESYS: Unsigned 32-bit
+ * value, boost applied to current BSSID to ensure the currently
+ * associated BSSID is favored so as to prevent ping-pong situations.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_ALERT_ROAM_RSSI_TRIGGER: Signed 32-bit
+ * value, RSSI below which "Alert" roam is enabled.
+ * "Alert" mode roaming - firmware is "urgently" hunting for another BSSID
+ * because the RSSI is low, or because many successive beacons have been
+ * lost or other bad link conditions.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_SET_LAZY_ROAM_ENABLE: Unsigned 32-bit
+ * value. 1-Enable, 0-Disable. Represents "Lazy" mode, where
+ * firmware is hunting for a better BSSID or white listed SSID even though
+ * the RSSI of the link is good. The parameters enabling the roaming are
+ * configured through the PARAM_A_BAND_XX attrbutes.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_SET_BSSID_PREFS: Nested attribute,
+ * represents the BSSIDs preferred over others while evaluating them
+ * for the roaming.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_SET_LAZY_ROAM_NUM_BSSID: Unsigned
+ * 32-bit value. Represents the number of preferred BSSIDs set.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_SET_LAZY_ROAM_BSSID: 6-byte MAC
+ * address representing the BSSID to be preferred.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_SET_LAZY_ROAM_RSSI_MODIFIER: Signed
+ * 32-bit value, representing the modifier to be applied to the RSSI of
+ * the BSSID for the purpose of comparing it with other roam candidate.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_SET_BSSID_PARAMS: Nested attribute,
+ * represents the BSSIDs to get blacklisted for roaming.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_SET_BSSID_PARAMS_NUM_BSSID: Unsigned
+ * 32-bit value, represents the number of blacklisted BSSIDs.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_SET_BSSID_PARAMS_BSSID: 6-byte MAC
+ * address representing the Blacklisted BSSID.
+ *
+ * @QCA_WLAN_VENDOR_ATTR_ROAMING_PARAM_SET_BSSID_PARAMS_HINT: Flag attribute,
+ * indicates this BSSID blacklist as a hint to the driver. The driver can
+ * select this BSSID in the worst case (when no other BSSIDs are better).
