Subject: Docs bug or argument handling error in iproute2 xt action

>From doc/actions/ifb-README in the iproute2 repo:
===================
# redirect all IP packets arriving in eth0 to ifb0
# use mark 1 --> puts them onto class 1:1
$TC filter add dev eth0 parent ffff: protocol ip prio 10 u32 \
match u32 0 0 flowid 1:1 \
action ipt -j MARK --set-mark 1 \
action mirred egress redirect dev ifb0
===================

Other documentation says 'ipt' has been replaced by 'xt',
but the passing of arguments other than the jump target doesn't seem to work at all with xt.

Running the above with s/ipt/xt/ gets me:
====
xt: unrecognized option '--set-mark'
Killed
