The extra_args argument ($3) of isochron_recv_start is overwritten with
uds ($2), if that argument exists.

This is currently not a problem, because the only TSN selftest
(ocelot/psfp.sh) omits remote sync so it does not specify to the
receiver a UNIX domain socket for ptp4l. So $uds is currently an empty
string.
