Parallel diagnostic loopback.
This feeds back all transmitted cells into the
receiver between the parallel/serial converters.
The transmitter
operates normally.
.It Dv UTP_LOOP_TWIST (0x10)
.It Dv UTP_LOOP_TWIST Pq No 0x10
Twisted pair diagnostic loopback.
Connects the high speed receive data to the
high speed transmit data.
All received data is sent back.
The receiver
operates normally.
.It Dv UTP_LOOP_PATH (0x20)
.It Dv UTP_LOOP_PATH Pq No 0x20
Diagnostic path loopback.
This connects the receiver input to the transmitter
output just between the path overhead processor and the byte mux.
The
transmitter operates normally.
