* @QCA_ROAM_REASON_UNKNOWN: Any reason that do not classify under the below
* reasons.
*
* @QCA_ROAM_REASON_PER: Roam triggered when packet error rates (PER) breached
* the configured threshold.
*
* @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.
