Subject: Iproute2 tc pfifo_fast not work

Hi Stephen.

I've found that I can't add pfifo_fast qdisc to my tc class tree. It 
just says:
-----------
# /sbin/tc qdisc add dev eth3 parent 2:299B handle 299B: pfifo_fast
qdisc 'pfifo_fast' does not support option parsing
-----------
And nothing else happends.
strace /sbin/tc qdisc add dev eth3 parent 2:299B handle 299B: pfifo_fast 
&> tc_pfifo_strace.txt
attached.

Kernel version 2.6.31, .config attached.
tc version 2.6.31.

I do something wrong or this is a bug?

For now I've switched to PRIO QDISC which seems to work fine, but it 
would be great to use lithweigth pfifo_fast instead of prio...
