 /**
+ * DOC: FILS shared key authentication offload
+ *
+ * FILS shared key authentication offload can be advertized by drivers by
+ * setting @NL80211_EXT_FEATURE_FILS_SK_OFFLOAD flag. The drivers that support
+ * 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_USERNAME - used to construct keyname_nai
+ *	%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_PMKID - used to identify the PMKSA used/generated
+ *	%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
+ * %NL80211_CMD_DEL_PMKSA are enhanced to allow support for PMKSA caching based
+ * on FILS cache identifier. Additionally %NL80211_ATTR_PMK is used with
+ * %NL80211_SET_PMKSA to specify the PMK corresponding to a PMKSA for driver to
+ * use in a FILS shared key connection with PMKSA caching.
