[RP-PPPoE] radattr.so cant receive values from radius

[Evgeniy Kozhuhovskiy]

You can try this one:

if cat /var/run/radattr.${IFNAME} |grep Upstream-Speed-Limit
then
  UP=`cat /var/run/radattr.${IFNAME} |grep Upstream-Speed-Limit |awk 
'{print $2}'`
  DOWN=`cat /var/run/radattr.${IFNAME} |grep Downstream-Speed-Limit |awk 
'{print $2}'`
fi

#[ -z $UP ] && UP=128
#[ -z $DOWN ] && DOWN=256

[ -z $UP ] && [ -z $DOWN ] && exit

/sbin/tc qdisc del dev $IFNAME root
/sbin/tc qdisc add dev $IFNAME root tbf rate ${DOWN}Kbit latency 10ms 
burst $[$DOWN*128]

/sbin/tc qdisc del dev $IFNAME handle ffff: ingress
/sbin/tc qdisc add dev $IFNAME handle ffff: ingress
/sbin/tc filter add dev $IFNAME parent ffff: protocol ip prio 10 u32 
match ip src 0.0.0.0/0 police rate ${UP}Kbit burst $[$DOWN*128] mtu 9k 
drop flowid :1
