26.4.1 ENET MAC Interrupt Event Register (HW_ENET_MAC_EIR)
When an event occurs that sets a bit in HW_ENET_MAC_EIR, an interrupt occurs if the
corresponding bit in the interrupt mask register (HW_ENET_MAC_EIMR) is also set.
Writing a 1 to an HW_ENET_MAC_EIR bit clears it; writing 0 has no effect. This register
is cleared upon hardware reset.

Reserved bits. Write as 0.
Babbling receive error. This bit indicates a frame was received with length in excess of MAX_FL bytes.
Babbling transmit error. This bit indicates the transmitted frame length exceeds MAX_FL bytes. This condition
usually caused by a frame that is too long placed into the transmit data buffer(s). Truncation does not occur.
