/**
* nm_utils_security_valid:
* @type: the security type to check AP flags and device capabilties against,
* e.g. #NMU_SEC_STATIC_WEP
* @wifi_caps: bitfield of the capabilities of the specific WiFi device, e.g.
* #NM_WIFI_DEVICE_CAP_CIPHER_WEP40
* @have_ap: whether the @ap_flags, @ap_wpa, and @ap_rsn arguments are valid
* @adhoc: whether the capabilities being tested are from an Ad-Hoc AP (IBSS)
* @ap_flags: bitfield of AP capabilities, e.g. #NM_802_11_AP_FLAGS_PRIVACY
* @ap_wpa: bitfield of AP capabilties derived from the AP's WPA beacon,
* e.g. (#NM_802_11_AP_SEC_PAIR_TKIP | #NM_802_11_AP_SEC_KEY_MGMT_PSK)
* @ap_rsn: bitfield of AP capabilties derived from the AP's RSN/WPA2 beacon,
* e.g. (#NM_802_11_AP_SEC_PAIR_CCMP | #NM_802_11_AP_SEC_PAIR_TKIP)
*
* Given a set of device capabilities, and a desired security type to check
* against, determines whether the combination of device, desired security
* type, and AP capabilities intersect.
*
* Returns: TRUE if the device capabilities and AP capabilties intersect and are
* compatible with the desired @type, FALSE if they are not
