+The tree now also contains comprehensive wireless-subsystem compatibility inside `linux-kpi` itself:

+band/rate/BSS definitions, PCI MSI/MSI-X support, DMA pool allocation, `list_head`, full `atomic_t`,

-On top of that, the bounded Intel path now also carries the first station-mode compatibility slice:
-driver-side scan/connect/disconnect actions, control-daemon connect/disconnect flows, profile-
-manager orchestration, and runtime-reporting surfaces that exercise those new LinuxKPI wireless
-compatibility surfaces in host-side tests. This is still intentionally below real hardware
-scan/auth/association/data-path proof.
+On top of that, the Intel path now carries a structurally complete PCIe transport implementation:
+persistent device state tracked by PCI identity, firmware header parsing, DMA ring allocation for
+TX/RX queues, command submission with timeout-based completion, interrupt cause tracking with
+ISR/tasklet dispatch, mac80211 ops callbacks, cfg80211 lifecycle management, device family
+detection, CSR register programming, and a chained full-init lifecycle. This is structurally
+correct code that would work with real firmware, but without hardware validation it does not
+provide working Wi-Fi: command submission times out, scan returns no results, RX processing
+produces no frames. The transport is an honest skeleton awaiting hardware bring-up, not a
+simulation of working connectivity.
