+.B bridge
+- behave as simple bridge between different macvlan interfaces on the same
+port. Frames from one interface to another one get delivered directly and are
+not sent out externally. Broadcast frames get flooded to all other bridge
+ports and to the external interface, but when they come back from a reflective
+relay, we don't deliver them again. Since we know all the MAC addresses, the
+macvlan bridge mode does not require learning or STP like the bridge module
+does.
+.sp
+.B passthru
+- allows takeover of the underlying device and passing it to a guest using
+virtio with macvtap backend. Only one macvlan device is allowed in passthru
+mode and it inherits the mac address from the underlying device and sets it in
+promiscuous mode to receive and forward all the packets.

+- allows one to set a list of allowed mac address, which is used to match
+against source mac address from received frames on underlying interface. This
+allows creating mac based VLAN associations, instead of standard port or tag
+based. The feature is useful to deploy 802.1x mac based behavior,
