Selecting this option, rx has priority over Tx (only for Giga

Ethernet device).

By default, the DMA arbitration scheme is based on Round-robin

Some ST SoCs (for example the stx7141 and stx7200c2) have two

Use an external timer for mitigating the number of network

to use the TMU channel 2 and the SH-RTC device.
