1588 Port 0(Host MAC) TX Interrupt (1588_MII_TX_INT)
This interrupt indicates that a packet from the Host MAC to the switch fabric
matches the configured PTP packet and the 1588 clock was captured.
This interrupt indicates that a packet from the Host MAC to the switch fabric
matches the configured PTP packet and the 1588 clock was captured.
Note:
For Port 0, receive is defined as data from the switch fabric, while
transmit is to the switch fabric.
transmit is to the switch fabric.

Note:
This bit is also cleared by an active edge on GPIO[9:8] if enabled.
For the clear function, GPIO inputs are edge sensitive and must be
active for greater than 40 nS to be recognized as a clear input.
