/**
* enum qca_wlan_concurrent_sta_policy_config - Concurrent STA policies
*
* @QCA_WLAN_CONCURRENT_STA_POLICY_PREFER_PRIMARY: Preference to the primary
* STA interface has to be given while selecting the connection policies
* (e.g., BSSID, band, TX/RX chains, etc.) for the subsequent STA interface.
* An interface is set as primary through the attribute
* QCA_WLAN_VENDOR_ATTR_CONFIG_CONCURRENT_STA_PRIMARY. This policy is not
* applicable if the primary interface has not been set earlier.
*
* The intention is not to downgrade the primary STA performance, such as:
* - Do not reduce the number of TX/RX chains of primary connection.
* - Do not optimize DBS vs. MCC/SCC, if DBS ends up reducing the number of
* chains.
* - If using MCC, should set the MCC duty cycle of the primary connection to
* be higher than the secondary connection.
*
* @QCA_WLAN_CONCURRENT_STA_POLICY_UNBIASED: The connection policies for the
* subsequent STA connection shall be chosen to balance with the existing
* concurrent STA's performance.
* Such as
* - Can choose MCC or DBS mode depending on the MCC efficiency and hardware
* capability.
* - If using MCC, set the MCC duty cycle of the primary connection to be equal
* to the secondary.
* - Prefer BSSID candidates which will help provide the best "overall"
* performance for all the STA connections.
