prioritize trafic going throught radio bridge

There is radio bridge configured as http://wiki.mikrotik.com/wiki/Transparently_Bridge_two_Networks
MT1 ↔ MT2.
After MT1 - our router (FreeBSD). After MT2 - router of ISP.
FreeBSD Router ↔ MT1 ↔ MT2 ↔ ISP router
I need to prioritize trafic going throught radio bridge MT1 ↔ MT2.
p2p - low
http,ftp - medium
games (port 27015 and some other ports) - hight
Please, help with config )
Thank you.

You should treat the bridge as a dumb wire and prioritize / manage your traffic on the devices on either side. Just my 2c
