WPS with multiple BSSID

[Eliad Peller]

hi Jouni,

(i have some multiple-bssid related patches i want to upstream, and i
want to make sure i actually understand the intended operation mode
here)

can you please explain the logic behind this (ancient) commit:

commit 9290cc1

    Apply hostapd WPS commands to all interfaces on concurrent APs

    When the same hostapd process is controlling multiple interfaces,
    apply WPS commands (push button, add PIN, change AP PIN) to all
    interfaces that are configured to use WPS.

since every bssid can have its own control interface and WPS state,
why would WPS command sent to a single interface (e.g. WPS_PBC) should
affect all the other ones as well?

thanks,
Eliad.
