+For
+.IR bridge (3)
+and
+.IR ethermultilink (8),
+the physical interface can be bypassed by writing
+.B bypass
+to the
+.B ctl
+file.
+This means that packets transmitted on the interface
+are not physically sent out but looped back to the bypass
+.B data
+file and packets
+received on the physical interface are ignored.
+Writing a packet to the bypass
+.B data
+file loops it back as if it was received
+on the physical interface.
