Add service task schedule to set_rx_mode. In some cases there are error messages printed out in PTP application (ptp4l): ptp4l[13848.762]: port 1 (ens2f3np3): received SYNC without timestamp ptp4l[13848.825]: port 1 (ens2f3np3): received SYNC without timestamp ptp4l[13848.887]: port 1 (ens2f3np3): received SYNC without timestamp This happens when service task would not run immediately after set_rx_mode, and we need it for setup tasks. This service task checks, if PTP RX packets are hung in firmware, and propagate correct settings such as multicast address for IEEE 1588 Precision Time Protocol. RX timestamping depends on some of these filters set. Bug happens only with high PTP packets frequency incoming, and not every run since sometimes service task is being ran from a different place immediately after starting ptp4l.
