I'm not sure if this will work. I think random-detect in this
situation will get FE's bandiwdth as reference and it will start
dropping packets when closing to 100Mb. While you can not apply
random-detect on subif, it is useless if you rate-limit on subif,
especialy if you have many subintterfaces with different limits.
