Phase 6.2: the MLD driver logic is now Rust, not C. The legacy C
linux_mld.c remains only as a thin transport-level helper (init/parse
functions for C structs used by linux_port.c); all MLD state management,
notification dispatch, TX/scan/sta management, and MLO RX parsing is
now in proper Rust.
src/mld.rs (744 lines):
- Complete firmware command ID table: all 7 command groups with
WIDE_ID encoding, 50+ command/notification IDs from Linux fw/api
- OpMode selection: BZ→iwlmld, others→iwlmvm (Linux iwl-drv.c)
- MldState: fw_running, radio_kill, scan, TX queue array[512],
notification counters (AtomicU32)
- NotifResult: decoded notification (handled/is_rx_frame/signal/rate/
wide_id/group/cmd/kind)
- handle_notification(): full WIDE_ID dispatch — all legacy + grouped
notifications, RX MPDU via parse_rx_mpdu, counted by type
- parse_rx_mpdu(): MLO RX MPDU parser — link_id from mac_phy_band,
AMSDU flags, signal/rate via FFI to legacy C Mini-MVM parser
(no duplicate parser per upstream-first rule)
- MldState::firmware_init(): records init sequence
- MldState::start/stop_scan(): scan state management
- MldState::add/remove_sta(): station ID validation
- MldState::alloc/free_txq(): TVQM queue allocation
- FFI to C: rb_iwl_mvm_detect_signal/rate_to_mcs via unsafe extern
- 11 unit tests covering: opmode selection, WIDE_ID encoding, state
init, firmware init, TXQ alloc/free, scan management, station
management, legacy + grouped + unknown notification dispatch,
notif_kind coverage
All 19 tests pass (11 MLD + 7 existing + 1 integration). The module
is integrated via 'mod mld;' in main.rs.
