- Because hostapd calls iv_key_set() before if_init(), make sure key_set
callback function will be executed, and that the key won't be deleted during the init process. - txmic and rxmic are written into the chip the same place regardless of opmode. - Make the hardware generate 802.11 sequence numbers.
