hello marcin... current radius rfc (rfc2865) didnt say anything about tx/rx
data rate limitation radius attribute... but there is a way how to do it
with freebsd :->

since freebsd ppp supported RAD_FILTER_ID and part of the access-accept
radius packet type... just simply send the label to FILTER_ID radius
attribute and put that label into /etc/ppp/ppp.linkup file where inside that
label is doing the bandwidth management using IPFW as its bandwidth
manager... just make sure you do a cleanup (removing ipfw pipe rules) inside
/etc/ppp/ppp.linkdown file upon disconnection...

you need a pipe number for ipfw for identification for that connection...
just play with the tunnel interface number as its pipe number for easy
creating and removing pipe :->
