* connection quality monitoring with multiple thresholds
  * support for FILS shared key authentication offload

* FILS shared key authentication offload should be able to construct the
* authentication and association frames for FILS shared key authentication and
* eventually do a key derivation as per IEEE 802.11ai. The below additional
* parameters should be given to driver in %NL80211_CMD_CONNECT.

* %NL80211_ATTR_FILS_ERP_REALM - used to construct keyname_nai
* %NL80211_ATTR_FILS_ERP_NEXT_SEQ_NUM - used to construct erp message
* %NL80211_ATTR_FILS_ERP_RRK - used to generate the rIK and rMSK
* rIK should be used to generate an authentication tag on the ERP message and
* rMSK should be used to derive a PMKSA.
* rIK, rMSK should be generated and keyname_nai, sequence number should be used
* as specified in IETF RFC 6696.
*
* When FILS shared key authentication is completed, driver needs to provide the
* below additional parameters to userspace.
* %NL80211_ATTR_FILS_KEK - used for key renewal
* %NL80211_ATTR_FILS_ERP_NEXT_SEQ_NUM - used in further EAP-RP exchanges

* %Nl80211_ATTR_PMK - used to update PMKSA cache in userspace
* The PMKSA can be maintained in userspace persistently so that it can be used
* later after reboots or wifi turn off/on also.
*
* %NL80211_ATTR_FILS_CACHE_ID is the cache identifier advertized by a FILS
* capable AP supporting PMK caching. It specifies the scope within which the
* PMKSAs are cached in an ESS. %NL80211_CMD_SET_PMKSA and
