Minstrel and its 802.11n support is a rate control algorithm. Some wireless drivers might require it enabled.

), the driver won't be able to load regulatory.db from /lib/firmware resulting in broken regulatory domain support. Please set CONFIG_CFG80211=m or add regulatory.db and regulatory.db.p7s (from net-wireless/wireless-regdb) to CONFIG_EXTRA_FIRMWARE.
