Thank you, Edward !
oops, it was blind copy-paste from ctl.conf(5) 

Now I can use native iscsi target/initiator on my fresh laptop and
desktop, thanks :)

Also I have  another machine (oooold HEAD, r239646) 
current# cat /etc/iscsi.conf
tiger {
        TargetAddress=192.168.9.98
        TargetName=iqn.desktop:target0
}
current# kldload iscsi_initiator
current# iscontrol -dt 192.168.9.98
TargetName=iqn.desktop:target0
current# iscontrol -n tiger
current# iscontrol[43727]: running
iscontrol[43727]: (pass1:iscsi0:0:0:0):  tagged openings now 0
dmesg:
