Hi Stefan
This is probably specific to the 6097 family. It works fine without
this on other devices. Creating a bridge like above and pinging across
it is one of my standard tests. But i only test modern devices like
the 6165, 6352, 6351, 6390 families.
In fact, you might need to review all the code and look where
mv88e6xxx_6095_family(chip) is used and consider if you need to add
mv88e6xxx_6097_family(chip). e.g.
if (mv88e6xxx_6095_family(chip) || mv88e6xxx_6185_family(chip)) {
/* Set the upstream port this port should use */
reg |= dsa_upstream_port(ds);
/* enable forwarding of unknown multicast addresses to
* the upstream port
*/
if (port == dsa_upstream_port(ds))
reg |= PORT_CONTROL_2_FORWARD_UNKNOWN;
}
Maybe this is your problem?
