I'm not sure this is the XML file. It looks like the traffic is going
from your block to the radio block controller because the outgoing SID
is not set properly.
However, the outgoing ctrl_iface SID is derived from the incoming
packet. Have you had other blocks work in the past?
Did it stop working when you added the argument?
And does it pass `uhd_usrp_probe`?
