_data_basic_send() and _data_basic_send_netkit_psp_assoc() currently only verify unidirectional data transmission from the test socket to psp_responder. As a result, they do not exercise the receive path for PSP-encrypted TCP data segments arriving at the test socket (such as packets redirected across a netkit interface associated via dev-assoc, which relies on SKB_EXT_PSP surviving packet scrubbing). Use the existing "data echo" command in psp_responder to verify that the test socket can also receive PSP-encrypted data from the peer in both _data_basic_send() and _data_basic_send_netkit_psp_assoc().
