Does tgt-admin supports bs-type sheepdog?

Hello all!

I've got installed tgt-1.0.60, iI'm trying to define sheepdog store in
targets.conf file. Content of targets.conf is:
# cat /etc/tgt/targets.conf
default-driver iscsi

<target iqn.backup.sheep:usun>
        bs-type sheepdog
        backing-store tcp:127.0.0.1:7000:usun
</target>

but tgt-admin throws:
# tgt-admin -p -e
# Adding target: iqn.backup.sheep:usun
tgtadm -C 0 --lld iscsi --op new --mode target --tid 1 -T
iqn.backup.sheep:usun
# Skipping device: tcp:127.0.0.1:7000:usun
# tcp:127.0.0.1:7000:usun does not exist - please check the
configuration file
tgtadm -C 0 --lld iscsi --op bind --mode target --tid 1 -I ALL


Does tgt-admin supports sheepdog or I made a mistake in targets.conf?
