Module dot11 

IEEE 802.11 (WiFi / Dot11) protocol layer implementation.

Provides full 802.11 frame parsing, building, and field access including:

• Frame Control field parsing (type, subtype, flags)
• Variable address fields (1-4 MAC addresses depending on frame type)
• Sequence control field
• FCS variant (Dot11FCS)
• RadioTap header support
• Management, control, and data frame subtypes
• Information elements (IEs)
• Security wrappers (WEP, TKIP, CCMP)

Modules

builder

IEEE 802.11 frame builder.

control

IEEE 802.11 control frame subtypes.

data

IEEE 802.11 data frame subtypes and QoS handling.

ie

IEEE 802.11 Information Elements (IEs).

management

IEEE 802.11 management frame subtypes.

offsets

Field offsets within the 802.11 header. NOTE: Frame Control is little-endian.

radiotap

RadioTap header implementation for IEEE 802.11 frames.

security

IEEE 802.11 security wrappers (WEP, TKIP, CCMP).

types

IEEE 802.11 constants, type codes, and name lookup functions.

Structs

Dot11FcsLayer

IEEE 802.11 FCS layer - same as Dot11Layer but includes a 4-byte FCS trailer.

Dot11Layer

IEEE 802.11 layer - a zero-copy view into the packet buffer.

Constants

DOT11_FCS_LEN

FCS field length.

DOT11_MGMT_HEADER_LEN

Standard management/data header length: FC(2) + Dur(2) + Addr1(6) + Addr2(6) + Addr3(6) + SC(2) = 24.

DOT11_MIN_HEADER_LEN

Minimum 802.11 header length: FC(2) + Duration(2) + Addr1(6) = 10 bytes. Most frames have at least 24 bytes (3 addresses + seq ctrl).

DOT11_WDS_HEADER_LEN

WDS (4 address) header length: 24 + Addr4(6) = 30.

Functions

build_frame_control

Build a Frame Control u16 value from components.

crc32_ieee

Compute IEEE CRC32 (used for FCS).
