[PATCH] (1/4) delay scheduler enqueue always succeeds.
If underlying fifo enqueue fails, return the status not 0.
Same patch should apply to both 2.6 and 2.4

[PATCH] (2/4) delay scheduler - retry if requeue fails
If delay scheduler decides not to send the packet right away, it requeues
it. If the requeue fails, it should go and look again rather than waking
up prematurely.

[PATCH] (3/4) delay scheduler race with device stopped

Also, if requeuing the packet fails, it is probably because the queue became full
by a racing enqueue. So the right thing to do is to go back and try again.

netem usage example
I''m trying to setup a netem delay with no luck (using iproute2-2.6.8,
compilation broke during arpd compile, so I use the
tc binary in the tc/ subdir, there''s also a q_netem.so there).
kernel is 2.6.8.1, compile with CPU cycle counter as time reference.
I was using sch_delay of 2.6.7 happily with something like:
tc qdisc add dev eth0 root 1: delay latency 1ms rate 35M
now I use:
tc qdisc add dev eth0 root netem latency 1ms
and it complain about "unknown qdisc netem"
do you have usage example with the new netem "scheduler"?
thanks

Using Token Bucket Filter to simulate a low bandwidth radio link
Hello,
I am attempting to use the LARTC traffic control to simulate a radio link that
has variable bandwidth and availability. The basic bandwidth could be as low
as 500 bits/sec but will generally be about 4000 bits/sec. If the simulated
radio link is unavailable (zero bandwidth) then packets should be queued
until a link is re-established.
i.e. Initial bandwidth is 5000bits/sec
then to 0
