- btintel.rs: run_intel_command() sends a command and waits for the
matching command-complete (opcode + status check). intel_read_version()
parses the Intel version response. intel_download_firmware() streams
the full SFI command sequence (CSS header + PKey + signature + payload
fragments), rejecting on controller NACK. intel_setup_firmware()
orchestrates bootloader detection -> enter MFG -> download -> exit MFG
-> DDC apply -> version re-read. apply_ddc_config() replays the DDC
command records. read_firmware_blob() probes scheme and /lib/firmware
(flat + intel/ layouts).
- main.rs: wire intel_setup_firmware into daemon_main for Intel CNVi
adapters (vendor 0x8087) before standard HCI init; no-op on
operational controllers, non-fatal on failure.
- 4 new tests (download ACK/NACK, opcode match/mismatch); 164 total pass.
Ported from Linux drivers/bluetooth/btintel.c.
