.Pp
The TXCSUM capability is disabled for any interface added to the bridge, this
is restored when the interface is removed again.
+.Pp
+The bridge supports monitor mode where the packets are discarded after
+.Xr bpf 4
+processing, the bridge will not process or forward the packets further.
+This can be used to multiplex the input of two or more interfaces into a single
+bpf stream.
+This is useful for reconstructing the traffic for network taps
+that transmit the RX/TX signals out through two separate interfaces.
