| help |
| This option allows to configure the priority of the RX thread that |
| handles incoming Ethernet packets. |
| Switching between preemptive and cooperative scheduling can be done by |
| NET_TC_THREAD_PREEMPTIVE. |
| Preemptive scheduling can lead to more responsive handling of network traffic, |

| other multicast is dropped by the MAC. If disabled then all |
| multicast is received by the MAC. |
