how to add XXXX the last 4 digits of the mac address in every device

could this be something ?

check if the SSID is OpenWRT, if it isn't, terminate, otherwise, make the changes.

Hi, modify file: package/kernel/mac80211/files/lib/wifi/mac80211.sh to generate all in /etc/config/wireless

the ssid line:
set wireless.wifi_ap${devidx}.ssid=OpenWrt_$(cat /sys/class/ieee80211/${dev}/macaddress|awk -F ":" '{print $3""$4""$5""$6 }'| tr a-z A-Z)

$3""$4""$5""$6 take the last 4 chars.
tr a-z A-Z convert it to upper case.
