+ *
+ * @QCA_ROAM_REASON_PER: Roam triggered when packet error rates (PER) breached

+ *
+ * @QCA_ROAM_REASON_BEACON_MISS: Roam triggered due to the continuous configured
+ * beacon misses from the then connected AP.
+ *
+ * @QCA_ROAM_REASON_POOR_RSSI: Roam triggered due to the poor RSSI reported
+ * by the connected AP.
+ *
+ * @QCA_ROAM_REASON_BETTER_RSSI: Roam triggered for finding a BSS with a better
+ * RSSI than the connected BSS. Here the RSSI of the current BSS is not poor.
+ *
+ * @QCA_ROAM_REASON_CONGESTION: Roam triggered considering the connected channel
+ * or environment being very noisy or congested.
+ *
+ * @QCA_ROAM_REASON_EXPLICIT_REQUEST: Roam triggered due to an explicit request
+ * from the user (user space).
+ *
+ * @QCA_ROAM_REASON_BTM: Roam triggered due to BTM Request frame received from
+ * the connected AP.
+ *
+ * @QCA_ROAM_REASON_BSS_LOAD: Roam triggered due to the channel utilization
+ * breaching out the configured threshold.
