The documentation says this:
A packet’s ingress port and physical ingress port are identical except
for packets processed by a switch feature such as bonding or tunneling
that makes a packet appear to arrive on a ``virtual’’ port associated
with the bond or the tunnel. For such packets, the ingress port is the
virtual port and the physical ingress port is, naturally, the physical
port. Open vSwitch implements both bonding and tunneling, but its bonding
implementation does not use virtual ports and its tunnels are typically
not on the same OpenFlow switch as their physical ingress ports (which
need not be part of any switch), so the ingress port and physical ingress
port are always the same in Open vSwitch.
For bonding, OVS in_port always matches on the physical input port.
For tunneling, OVS doesn't pass along the physical input port but only
the virtual one. You might be able to set the packet mark in the
physical bridge and then match on it in the virtual one, though.
