# BOARD_WLAN_DEVICE := bcmdhd selects the Broadcom wifi HAL implementation.

# netlink sockets, and resolves the nl80211 family ID.  The functions are
# Broadcom-generic, not bcmdhd-specific; any nl80211-compatible adapter
# (mt7921u, rtw88, ath9k_htc, etc.) works fine.
#

# WIFI_ERROR_NOT_SUPPORTED from init_wifi_vendor_hal_func_table, causing the
# AIDL wifi HAL (com.android.hardware.wifi) to fail at startup with "Can not
