Subject: hostapd: fix wpa_supplicant mac address allocation on ap+sta
X-Git-Tag: v23.05.0-rc4~2
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=02ed2b0271c5e17584884146649d7fb64a9ac35d;p=openwrt%2Fstaging%2Fhauke.git

hostapd: fix wpa_supplicant mac address allocation on ap+sta

If the full interface is restarted while bringing up an AP, it can trigger a
wpa_supplicant interface start before wpa_supplicant is notified of the
allocated mac addresses.
Fix this by moving the iface_update_supplicant_macaddr call to just after
the point where mac addresses are allocated.
