You don't actually describe your interface configuration. I _guess_ you are trying to terminate IP traffic directly on an svlan(4) interface. That sounds very unusual. Do we want to support this? I can see why it might fail. Since svlan(4) encapsulation is not covered by the hardware VLAN support, it changes the offsets to the IP/TCP headers, which is something the em(4) driver doesn't handle. For bge(4), the chip probably gets confused. -- Christian "naddy" Weisgerber na...@mips.inka.de
