That's right, such configuration happens by using VLAN_CTL in the context of SF2, by default only Port <N> and CPU can talk to each other. Bridging ports involving putting them in the same domain, e.g: updating the VLAN_CTL bitmask to include all bridge members. -- Florian -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
