Hm, so - how does this expose the CPU facing port(s), if any? ray@ is trying to figure out how to expose the arge0/arge1 interface (as he's got at least one board where the switch PHY hangs off of arge1, not arge0) so things are probed/attached "right". That discussion may be worth having here. :) Whats RTL8366RB_SGCR_EN_VLAN_4KTB do? Adrian
