601-ucode_support.patch adds the first link of an AP MLD on the
existing netdev with no address, and hostapd_setup_bss() then takes the
netdev address, the MLD address, as the link address. A link on a
radio other than radio 0, whose configured BSSID hostapd.uc keeps apart
from the MLD address (bss_mld_addr()), beaconed with the MLD address,
while ubus get_status reported the configured BSSID. A subscriber that
built its BSS Transition candidates from get_status named a BSSID that
nothing transmitted.
Add a patch that keeps the configured BSSID as the link address and
takes the netdev address as the MLD address, as hostapd_driver_init()
does for the first interface. Without a configured BSSID, the link
takes a random address with the OUI of the netdev, as
hostapd_driver_init() does (pre_setup_mld), so that the link address
cannot be the MLD address: a later link that is given the MLD address
as its BSSID would fail ADD_LINK with -EALREADY. hostapd.uc always sets
a BSSID, so OpenWrt configurations take the configured address.
Have get_status and the channel-switch event report hapd->own_addr,
the address the BSS transmits with, instead of conf->bssid, which is
all zeros where the configuration names none.
