Add the new attribute "key_flag" which will in the following patches replace the boolean "set_tx" with something also able to handle "Extended Key ID for Individually Addressed Frames" from IEEE 802.11-2016. The following flag are defined: KEY_FLAG_MODIFY Set when an already installed key must be updated. So far the only use-case is changing RX/TX status of installed keys. Must not be set when deleting a key. KEY_FLAG_DEFAULT Set when the key is also a default key. Must not be set when deleting a key. (This is the replacement for set_tx.) KEY_FLAG_RX The key is valid for RX. Must not be set when deleting a key. KEY_FLAG_TX The key is valid for TX. Must not be set when deleting a key. KEY_FLAG_GROUP The key is a broadcast or group key. KEY_FLAG_PAIRWISE The key is a pairwise key. KEY_FLAG_PMK The key is a Pairwise Master Key (PMK). Predefined and needed flag combinations so far are: KEY_FLAG_GROUP_RX_TX WEP key not used as default key (yet). KEY_FLAG_GROUP_RX_TX_DEFAULT Default WEP or WPA-NONE key. KEY_FLAG_GROUP_RX GTK key valid for RX only. KEY_FLAG_GROUP_TX_DEFAULT GTK key valid for TX only, immediately taking over TX. KEY_FLAG_PAIRWISE_RX_TX Pairwise key immediately becoming the active pairwise key. KEY_FLAG_PAIRWISE_RX Pairwise key not yet valid for TX. (Only usable with Extended Key ID support.) KEY_FLAG_PAIRWISE_RX_TX_MODIFY Enable TX for a pairwise key installed with KEY_FLAG_PAIRWISE_RX. KEY_FLAG_RX_TX Not a valid standalone key type and can only used in combination with other flags to mark a key for RX/TX. This patch is not changing any functionality. It just adds the new key_flag to all hostapd/wpa_supplicant set_key() functions without using it, yet.
