[sr-dev] t_relay() seems to generate error message on its own

according to t_relay() documentation:

Returns a negative value on failure--you may still want to send a negative reply upstream statelessly not to leave upstream UAC in lurch.

when t_relay cannot send request to the destination (no arp response), it seems to be generating on its own an error reply:

477 Unfortunately error sending to next hop occured

this then results in two error replies (another one from script).

is it true that the above error message is generated by t_relay()? if yes, is it somehow possible to get rid of it? in k tm module, there used to be a flag parameter to t_relay to control its error behavior.
