Without BOARD_WLAN_DEVICE, libwifi-hal's fallback returns
WIFI_ERROR_NOT_SUPPORTED from init_wifi_vendor_hal_func_table, which
causes the AIDL wifi HAL (com.android.hardware.wifi) to fail at startup:
E android.hardware.wifi-service: Can not initialize the vendor
function pointer table
E android.hardware.wifi-service: Wifi HAL start failed
The bcmdhd implementation of init_wifi_vendor_hal_func_table uses
purely generic nl80211 — it scans /sys/class/net/ for phy80211
interfaces, creates netlink sockets, and resolves the nl80211 family
ID via genl_ctrl_resolve(). There are no bcmdhd-specific IOCTLs or
vendor commands in the core startup path (wifi_initialize, wifi_cleanup,
wifi_event_loop, wifi_get_ifaces, wifi_get_iface_name); the vendor
commands are only used for optional advanced features (RTT, NAN, etc.)
that this device does not use.
