What is etherPortStatsTxBadFifoOverrun?

This counts bad frames transmitted due to a Transmit FIFO overrun, where data arrived into the output buffer faster than it could be drained. It signals an internal hardware timing or buffering problem on the transmit path of this port. An admin troubleshooting a card producing corrupted outbound traffic would check this alongside the underrun counter.
