No, I use something like tcpdump -i eth0 -w fq -c 300 after the netperf
start.

tc -s -d qdisc
qdisc fq 8001: dev eth0 root refcnt 2 [Unknown qdisc, optlen=64]
Sent 6680760347 bytes 4431855 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
btw, is the fq support for tc merged into iproute2? Looks like I can't
