Set ETH_MACCR_ROD unconditionally when configuring the MAC. In half-duplex mode the MAC otherwise reflects every frame it transmits back to its own receiver, flooding the receive path with our own traffic right as a genuine reply arrives. The bit has no effect in full-duplex (confirmed on our hardware: fduplex=1), so setting it unconditionally is safe and changes nothing observable for boards already running full-duplex. The sibling stm32f7 driver has the same gap (ETH_MACCR_ROD cleared but never set) and stm32h7's equivalent ETH_MACCR_DO bit has the same issue; both are left out of scope here since only m3m4_v1 hardware was available to validate against.
