6. Aborted Transmission Due to FIFO Empty - Tx MAC Application Interface
(Gigabit Mode)
If the tx_fifoempty is asserted while the Tx MAC is in the process of reading a frame, the MAC will stop reading
the frame and assert tx_disfrm to indicate an erroneous transmission. The frame transmission is abandoned
when this occurs.
