CONSTANTS

NameValueTypeDescription
CCMP_128_MIC_LEN 8 uint32
CCMP_256_MIC_LEN 16 uint32
CCMP_HDR_LEN 8 uint32

IEEE Std 802.11-2016 12.5.3.2
CCMP_PN_LEN 6 uint32
MAC_ADDR_LEN 6 uint8
MAX_MESH_ID_BYTE_LEN 32 uint8

IEEE Std 802.11-2016, 9.4.2.99
MAX_MGMT_FRAME_MAC_HEADER_BYTE_LEN 28 uint8

IEEE Std 802.11-2016, 9.3.3.2
MAX_MMPDU_BYTE_LEN 2304 uint16

IEEE Std 802.11-2016, 9.2.4.7
MAX_SSID_BYTE_LEN 32 uint8

IEEE Std 802.11-2016, 9.4.2.2 The maximum length of an SSID is 32 bytes, even when the SSID should be interpreted using UTF-8 encoding (see Table 9-135). While every length in the 802.11 standard is byte oriented, the word BYTE is included in the name of this constant to emphasize the importance that it not be applied to the length of a UTF-8 encoded string.
MAX_UNIQUE_CHANNEL_NUMBERS 256 uint16

The limit on the number of channels in a list of unique channel numbers is 256 since a channel number in IEEE 802.11-2016 cannot exceed one octet. See IEEE 802.11-2016 9.4.2.18 Supported Channels element for an example element that assumes a channel number does not exceed one octet.
MAX_VHT_MPDU_BYTE_LEN_0 3895 uint16
MAX_VHT_MPDU_BYTE_LEN_1 7991 uint16
MAX_VHT_MPDU_BYTE_LEN_2 11454 uint16
SSID_LIST_MAX 84 uint8

The limit on the number of SSIDs is 84 because an SSID List IE can contain no more than 84 one byte SSIDs. (Specifying a zero byte SSID in an SSID List with more than one SSID is valid but unnecessary since it is the wildcard SSID.)
TIDS_MAX 16 uint32

IEEE Std 802.11-2016, 9.2.4.5
WLAN_IE_BODY_MAX_LEN 255 uint32
WLAN_IE_MAX_LEN 257 uint32

IEEE Std 802.11-2016, 9.4.2.25.1 IEEE mentions that an element body maximum length is 255 octets in the RSN element section, but not in a dedicated section. Since the IE header is two octets, the whole IE max length is 257 octets.
WLAN_MSDU_MAX_LEN 2304 uint32

IEEE Std 802.11-2016, Table 9-19
