Can we please take one step back. I am not understanding how you guys
use the multiple interfaces. The multiple AP interfaces in brcmfmac are
only intended for Multiple-BSS feature as described in hostapd.conf
which changes wlan0 from STA to AP and creates additional AP interfaces,
but you seem to be creating an AP interface with iw next to a STA interface.
I actually have patches pending that correct the announced interface
combinations. I am currently on vacation as my family expanded with a
baby girl.
