protocol_parity_error: (DB)
Originally used for detecting parity error on coherent interface, however, no
parity checks exist. So this logs parity errors on data from the IIO switch on
the inbound path.
13:13 ROS_V 0x0
protocol_qt_overflow_underflow: (DA)
Used for queue/table overflow or underflow in coherent Interface protocol
layer.
